Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Tissue Staining

Q.7 Epithelium covers body surfaces, lines hollow organs and also forms gland. They serve as protective covers to the underlying tissues and prevents harm caused by physical, chemical and biological agents, to a significant extent. In addition, they also act as barriers, allowing the selected entry and exit of substances across the epithelium. The glandular epithelium has secretory function. Example: Epithelium of the pancreas, stomach, intestine, kidney. The epithelium lining the stomach and intestine help to absorb nutrients. (Henrikson, Kaye and Mazurkiewicz,1997) Q1. Micrograph A : Simple cuboidal epithelium. The cube shape of the cells and the centrally ...

People working in manufacturing and chemical industries are more prone to health hazards as they are exposed to dangerous substances that have adverse health effects on them. Frequent exposure to synthetic substances causes nausea, vomiting, and headaches, which, if not treated at earlier stages turn into life threatening diseases. These substances directly or indirectly exert toxic elements through biological, chemical, physical, genetic or psychological agents on living organisms and other biological systems, and this study is known as toxicology. In an organism these toxic elements are absorbed systematically through the skin, lungs, or gastro-intestinal tracts. The effect of these ...

Introduction

Cystic Fibrosis (CF) is the most prevalent genetic disorder in the Caucasian population, with an incidence of 1 in 2500 births. CF is a disease that affects many organs including the upper and lower respiratory tracts, pancreas, intestines and reproductive system. Over the past 20 years, our understanding of the manifestation and management of the disease has progressed dramatically. CF was once considered a condition of childhood and there was very little expectation that children would enter adult life. However, CF has become a multisystem adult disease with the increased survival attributable to advancements in standardized treatment, introduction of ...

Brief information, risk factors and symptoms

Colon cancer, that is also known as colorectal, is a type of cancer that starts from rectum or colon. As any other type of cancer, colon cancer is characterized by uncontrolled growing cells of the body. This type of cancer usually starts with a polyp – a kind of growth on the inner lining of the rectum or colon. However, it is important to know that not all polyps change into cancer, though some of them might do it after several years. The chances that a polyp will become cancer after some, depends on the type of polyps. There are ...

Diverticular is a disease that involves the appearance of pockets or small bulges in the intestine walls (NHS, 2016). The pockets may become infected or inflamed resulting into diverticulitis. Some of the symptoms of diverticular include bloating; and pain in the lower abdomen. Many people who suffer from diverticular do not exhibit any symptoms. In such a case the condition is referred to as diverticulosis. On the other hand, diverticulitis has some serious symptoms that include fever; diarrhea; and severe pain in the abdomen. The diverticular disease occurs on the walls of the colon. The responsibility of the colon ...

Magnesium is an essential nutrient

Magnesium is a mineral which is of great abundance in the human body. Along with enzymes, it is important for protein synthesis, muscle regulation and a host of other important cellular factors such as oxidative phosporylation, energy production which involves production and utilization of ATP and glycolysis. Additionally, Magnesium is required to assist in different cellular processes such as DNA replication and transcription and RNA translation(Barbagallo, 2012). Magnesium is found usually in the bones and or in the soft tissues of humans. Next to Potassium, it is the most abundant ion in the body. The plasma actually contains ...

Food Safety

Escherichia Coli commonly called E. coli is a variety of bacteria that is seen in the human intestine, and in the intestine of animals including big mammals. Even though many varieties of E. coli will not harm humans, certain varieties can lead to diseases. The most notorious version of E. coli is the E. coli O157: H7. This variety of E. coli leads to acute diarrhea in humans, and can even lead to serious medical conditions that cause harm to the kidneys. This variety of the bacteria produces a hazardous toxic compound called the Shiga toxin. Hence, this strand ...

Urinary diversions are ways of releasing urine from a patient’s body when they cannot urinate following a malfunction in the urinary system. The two general forms of diversions include incontinent and continent urinary diversions. The following is a further explanation as well as the advantages and disadvantages of each procedure. Incontinent Urinary Diversion is an old form of tract reconstruction. Blake et al. (2010) present it as the quickest and simplest form of urinary diversions due to its familiarity across many urologists and other physicians. In this procedure, urologists harvest a section of the small intestine, attach a ...

In most cases, hypolactasia (lactase deficiency) appears during the early childhood stage, and gradually increases in intensity as age increases. Note that the lactase enzyme (lactase-phlorhizin hydrolase) is an enzyme enabling the digestion and absorption of lactose, a carbohydrate found in dairy products and other food sources, which include milk and cheese. As effect, individuals with lactase deficiency experience lactose maldigestion (or malabsorption) when eating food rich in lactose. This symptom is most commonly referred to as lactose intolerance. A common characteristic of hypolactasia is that the condition first manifests as early as childhood. The condition can be diagnosed ...

Crohn’s disease is a chronic disease resulting in inflammation of the gastrointestinal tract. Usually, Crohn’s disease disturbs the small intestine as well as the starting portion of the large intestine, but it can also disturb any part of the gastrointestinal tract ranging from the mouth to the anus. Most commonly, the disease starts with less severity but with the passage of time, it becomes more serious. People in the age range of 20 to 29 years have more chances of developing the disease. Nearly 25% of new cases of Crohn’s disease are found ...

Dissertation: Are cognitive distortions the answer for the persistence of depression in treated Celiac disease patients?

Abstract The research suggests that Celiac patients are heavily influenced by their diagnosis. Anxiety, depression, and social isolation are all common features that sufferers of Celiac disease share. The disease functions in such a way that it forces the sufferer to remove him or herself from the social act of eating: he or she is no longer able to really be a part of the social gatherings that include food (Addolorato, 2001). However, this separation is largely invisible; many people do not realize that Celiac patients face any trouble at all in social situations. In this discussion, an investigation ...

HUMAN SYSTEMS

Musculoskeletal System As the name suggests, the “Musculoskeletal system” of the human body comprises of the bones and muscles mainly. Tendons and ligaments are also important parts of the system. The major function s of this particular system is to help in locomotion and to protect the delicate visceral organs.Some of the commonest diseases that we encounter as medical professionals, belonging to this particular system are Rheumatoid arthritis, Osteoarthritis, fractures of various bones of the body, tumors of the bones. Even diseases like TB may also develop in the bones but its development is always secondary to that of ...

Introduction

Cancer affects the body’s most basic unit, the cell. Normally, cells grow and divide to form new cells. When cells grow old, they die to make room for new ones and new cells grow only when the body needs them. However sometimes the old cells do not die or new cells are produced when not needed by the body they form tumors. Tumors can be either benign or malignant (National Cancer Institute, 2011). and organs.

Slide 2

Benign tumors are non-cancerous and when removed they do not grow back. Malignant tumors are cancerous and most instances life threatening. When malignant ...

Human digestive system is distinctively different from herbivores and carnivores. Herbivores normally have longer digestive system compared to human and herbivores have digestive anatomy and bacteria symbiosis that allow them to digest cellulose from plant materials. Cellulose digestion in herbivores is assisted by bacteria in the rumen (partitioned stomach) or in the cecum (hindgut fermentation) in the case of cows and horses respectively. Carnivores have shorter digestive system compared to human, as carnivore’s nutrition comes from meat that can readily be broken down by enzymes into protein and amino acids.

Human is categorized as omnivore, and human ...

The American Gastroenterological Association in 2007 defined the terms that we use to describe chronic blood loss. Occult bleeding is defined as a positive fecal occult blood sample on initial evaluation; or it is defined as iron deficiency anemia, without any signs of physical bleeding. The term obscure bleeding is defined as; bleeding that persists even after evaluation following an endoscopy, colonoscopy, and radiograph imaging. Obscure bleeding accounts for approximately 5% of all GI bleeds; 75% occur in the small intestines while the rest are associated with lesions of the upper or lower gastrointestinal tract.,, Depending on the location ...

Lipids insolubility in water is general. Lipids structure has great number of variety. There are two types of fatty acids naturally, may be saturated or unsaturated. Unsaturated acids have lesser melting point than saturated ones. There are two polyunsaturated fatty acids, linolenic and linoleic, their absence in the human diet has been associated with health problems so they designated essential. Their absence can cause scaly skin, increased dehydration and stunted growth.

- The role of the stomach is to act as the storage for food and allow its slow release into the small intestine at intervals. Also, it allows food churning which helps break the food into smaller particles for easier for digestion. It is also a site of absorption of some foods. The liver serves to regulate the amount of blood components that circulate in peripheral blood. This includes the regulation of blood concentration of glucose and lipids after digestion. It also secretes bile which is important in the digestion of fats in diet. Salivary glands produce saliva which helps ...

- The differences between the cardiovascular diseases and the coronary heart diseases

The major differences between these two types of diseases relates to the vascular components of the cardiovascular system. This simply means that the cardiovascular diseases do not only involve the heart alone but also involves all the heart linked vessels. i.e all arteries, veins and lymphatics found to be associated with the heart and blood passes to and from the heart. However, the coronary heart diseases only relate to the vessels that are within the heart itself and supply the heart itself and also the muscles of ...

Glycosylated Hemoglobin: HgA1c

Glycosylated hemoglobin is formed by the irreversible, non-enzymatic binding of circulating glucose to the amino groups of lysine and valine residues in hemoglobin. It is measured as a ratio of glycosylated hemoglobin to non-glycosylated hemoglobin. The level of HgA1c in erythrocytes depends on the concentration of glucose in blood. When level of blood glucose is high, the rate of glycation is increased, hence more glycosylated hemoglobin. Glycation occurs slowly and over the entire lifespan of the red blood cell, i.e. 90-120 days. Therefore, HbA1c reflects the average level of blood glucose exposed to the red blood cell over the past ...

Diarrhea and Constipation

There are a lot of pathologies and pathogens that could affect the normal flow of food and absorption in the digestive tract. Two common digestive problems, very common that it could be acquired by almost anyone, are diarrhea and constipation. These two digestive disorders are less severe compared to several cancers that could exist in the digestive system like colon cancer and liver cancer. Thus, diarrhea and constipation are easier to treat—these two are also very much easy to acquire.

As a brief background, Diarrhea is a bowel disorder wherein the classic symptom is an increase in the frequency of bowel ...

Crohn's Disease (CD): A Historical Background

Crohn’s disease is a persistent inflammatory bowel disease (IBD) that may impact any part of the gastrointestinal path, however, normally impacts the ileum (Yamada, 2009). It usually occurs to individuals of age 21 or under (Wilson et al., 2010). The CD may affect the quality of life (Baumgart & Sandborn, 2007; Morrison et al., 2009). It may need surgery (Pihl-Lesnovska et al., 2010). There is a steady global rise in the occurrence of Crohn’s Disease and it represents an increased hospitalization (Gibson, 2009; Morrison et al., 2009; Wilson et al., 2010). In 2009, the CD cases in Australia were ...

Introduction

Dietary fiber is a combined term for a diversity of plant matters that are resistant to digestion by human gastrointestinal enzymes. Dietary fibers can be categorized into two major groups according to their solubility in water. In humans, natural gel-forming fibers (gums, pectins, mucilage, and the remains of the hemicelluloses) are soluble. Whereas the matrix fibers or the structural (lignins, some hemicelluloses, and cellulose,) are insoluble, Dietary fiber and whole grains are among the best sources of nutrients including minerals, a slowly digestive energy and vitamins. (Byrne, 2011). They also contain phytochemicals such as carotenoids, lignans, inulin, beta-glucan and phenolic. These chemicals ...

Introduction:

In Pancreatitis, there is a disturbance in enzymatic secretion of pancreas. Usually trypsin that is used in digestion of food these are actuated in the pancreas. In normal condition, trypsin is activated in the small intestine; it acts as a central role in digestion of nutrient. When it is triggered in the pancreas, it causes inflammation of the pancreas ...

Abstract

Cystic fibrosis is an autosomal recessive genetic problem with major infections to lungs, pancres, intestine and liver. The main characteristic of the disease is abnormal transport of chloride, and sodium in the epithelium leading to thick secretions. It usually results from mutation in the gene for a protein known as cystic fibrosis trans-membrane conductance regulator (CFTR). This is a hormone which is usually involved in various body excretion processes. The main method of transmission of the disease is through genes. However, research has proved that it can be still transferred among people with no DNA connection The disease is ...

Colorectal cancer, which is also commonly known as colon cancer is the second leading cause of cancer related deaths in the US. According to statistics retrieved from the centers for disease control, approximately 100,000 new cases of colon cancer are detected every year. The incidence of colon cancer is observed more commonly in patients that belong to higher socioeconomic background. Furthermore, colon cancer is most commonly detected in patients who are 50 years or older (CDC.gov). It was observed that approximately 49000 deaths occur annually on account of colon cancer. The death rate for colon cancer has been ...

Digestion occurs in the gastrointestinal system, which is composed of the gastrointestinal tract (GI tract) and the associated accessory organs.The process of digestion occurs through six steps, namely ingestion, secretion, mixing,digestion, absorption and defecation. (Tortora&Derrickson, 2008).

Anatomy of the digestive system

The GI tract or the alimentary canal is a long winding tube that measures approximately 30 feet (9 meters) in length. The mouth, esophagus, pharynx, stomach, small intestine, large intestine and the anus make up the GI tract.The salivary glands, tongue, teeth, gallbladder, pancreas and the liver make up the associated accessory organs (Tortora&Derrickson, 2008). The mouth. The mouth starts with the ...

Psoriasis and Inflammatory Bowel Disease are two of the most prevalent types of immune disorders. Being diseases of the immune system, both diseases have similarities and, of course, striking differences. Reviewing both of their pathophysiology, incidences of occurrence and maladaptive responses may help us understand how these two immune disorders manifest their symptoms and affect the human body. Psoriasis is considered as the most prevalent autoimmune disorder, particularly the psoriasis vulgaris type (Krueger and Bowcock, 2005). Additionally, the prevalence of psoriasis considerably varies worldwide (Langley, Krueger, and Griffiths, 2005). In USA, an estimated 2% of the population is ...

Prior to the discovery of insulin, diabetes was dreaded as a disease leading to death. It was known that a rise in the sugar level in the body worsened the condition of diabetic individuals and that the sole treatment of diabetes known to people was to restrict the dietary intake of sugars (‘’The discovery of insulin”, n.d., para. 1). During the nineteenth century, examination of patients who succumbed to diabetes revealed that the pancreas was damaged. In 1869, Paul Langerhans discovered that a group of cells called beta cells, whose function was unidentified, existed within the pancreatic tissue and were eventually ...

2. How does exercise affect diabetes mellitus? During exercise, the whole-body oxygen consumption usually increases 20-fold. However, greater increases have been reported in the working muscles (American Diabetes Association). Under such circumstances, the skeletal muscles increase the utilization of stored triglycerides and glycogen, as well as the free fatty acids. Consequently, exercise maintains appropriate glucose levels in order to preserve the function of the central nervous system. In patients with diabetes mellitus, therefore, exercise ameliorates insulin sensitivity and helps to lower the elevated levels of blood glucose to the normal range (American Diabetes Association). 3. How does ...

Millions of animals undergo distressing scientific procedures, and some of these can be very painful. Does the Legislation of animal experimentation under modern societies make the issue ethically acceptable? The “3Rs” concept focuses on the efforts to replace, reduce and refine the animal testing and experiments. There is a continuing debate going on ethical issues of the use of animal in scientific experiments (Kolar111-22). Animal testing is nothing new in the society, and it has been done since centuries. The animals have been used in different researchers working in the areas of health and food. Earlier, the animals have been ...

Inflammatory bowel disease (IBD) is a chronic disease that refers to both the Crohn’s disease and ulcerative colitis. These two conditions are variants of IBD that often share some pathophysiological similarities and differences. The incidence of Crohn’s disease and ulcerative colitis may be influenced by familial or hereditary predisposition (Brant, 2007) that may be relevant in the case of the 38-year old male patient suffering from ulcerative colitis and whose aunt was previously diagnosed with a Crohn’s disease. According to Baumgart (2012), a heritability studies of IBD revealed a prominent genetic component. This hereditary disposition is about 75 to 80 ...

Introduction

Composition of Dietary Fiber Dietary fiber is an essential component in nutrition and health (Mora et al., 2013; Klosterbuer, Roughead, & Slavin, 2011). Thus, the present study will explore the effect of particle size and source of fiber on the level of cholesterol in the human digestion system. Primarily, dietary fiber is a constituent of plant foods and includes materials that have diverse morphological and chemical structure. Such materials resist enzymatic action in the human digestion system (Dhingra et al. 2012). In the gastrointestinal tracts, the dietary fiber forms a matrix that has both amorphous and fibrous characteristics. The matrix’s ...

The analysis is based on the report detailing my nutrient intake recorded for two days starting from September 4, 2014 to September 6, 2014. According to the analysis, my diet during the two-day period predisposes me to cardiovascular disease since it is high in saturated fats. According to the food guidelines given by USDA, saturated fats should contribute less than 10 percent of the total daily calories. However, my nutrient report indicates that saturated fats contribute 12 percent of my total daily calorie intake. Consequently, ...

Key concepts of a Gluten-free diet

The word gluten refers to the general term that describes the storage of proteins, or prolamins, that is found in wheat or “gliadin”, rye, barley and other derivatives that comes from these types of grains. The “gliadin” is that kind of protein that is involved in the pathophysiology of celiac disease (Guandalini 3). The people who are suffering from celiac diseases are prohibited to eat foods that contain gluten. The effect of gluten when eaten by people with celiac diseases is that their immune system of responds by damaging the small intestine. The lining in the small intestines ...

Impact of Technology on Animal Testing Issues

Introduction The use of animals in drug and medical testing has always been a controversial issue. Animal activists have faulted medical researchers for using animals as test subjects for new drugs. Animal testing is currently a multi- billion dollar industry that encompasses chemical and pharmaceutical industries, government bodies as well as university research centers. Millions of animals are subjected to intensive pains and stress in the course of experimental procedures and are exposed to very harsh environments for medical and drug research purposes (Kolar 112). The most common animals used animal testing include rats, mice, primates, rabbits, dogs and cats ...

Introduction

Symbiosis is the interaction two or more different organisms that generally live in close physical relationship. More often, these organisms are living for both of their advantages. Part of the normal lives of these organisms naturally depends to one another. On the other hand, other interaction between the biotic components of our ecosystem is the antibiosis. This interaction is an antagonistic relationship between two or more organisms in which commonly happens to microorganisms. In tis relationship, only one may be adversely affected. Also, the ecosystem’s biotic components interactions are normally controlled by various biotic and abiotic factors, which ...

Diabetes Facts

What is diabetes? It is a chronic condition, characterized by excessive amounts of blood sugar or glucose. Its full name is diabetes mellitus, although for the remainder of this paper the commonly used name diabetes will be used. When there is too much glucose in the blood – a condition known as hyperglycemia – glucose finds its way into the urine, which gave rise to the term “sweet urine.” (Stöppler and Shiel (Ed.), 2012). Glucose – in addition to being a simple sugar contained in various foods – is also a nutrient essential to the normal functioning of cells in the body. Carbohydrates in food ...

1. Diagnosis of the disease and justification (1 paragraph) The patient is suffering from constipation. Constipation mostly refers to having bowel movement less than three times per week. Constipation is usually accompanied by hard stools or passing of the stool is difficult. Furthermore, the patient suffering from constipation is experiencing pain while passing stools or he/she may not be able to have a bowel movement after straining for more than 10 minutes. The symptoms of constipation may also be, as a result, of the condition of the feces that changes from the normal or usual feces. Constipation is, therefore, refer ...

Research shows that around 30, 000 Americans have Cystic Fibrosis with over 1000 new cases diagnosed every year. Analysts suggest that it occurs evenly to both the females and males and affects generally every race. This condition is more common among the white babies. One in every 3,200 live white births in comparison to one in every 3,900 live births amongst all Americans appear to be suffering from the condition. At the age of three, most patients are diagnosed and only ten percent of the most recent cases are usually by age eighteen and above (Children’s ...

The Diverticular disease has three conditions that involve small sacks or pocket development in the lining of the intestine, formation of numerous tiny pockets, and the final condition is Diverticular bleeding. The disease has two clinical forms which are diveticlusis where there is the presence of Diverticular, but there are no symptoms and diverticulitis in which the diverticula have been inflamed and can cause fatal obstruction. The disease is common to those members of the society who are ageing ( ...

Introduction

There are a number of reasons that suggest people to choose vegetarianism. These reasons are mainly related to health, morality and environment, but there are several other reasons that argue in favor of vegetarianism. A huge number of people, on the other hand, do not accept that vegetarianism is the best food. This paper intends to discuss the vegetarianism and its health, moral and environmental benefits, along with discussing other aspects and benefits of the area under discussion.

Background

Traditionally, people believed that a vegetarian diets are low in nutrition and cannot supply the required amount of nutrition to the human body. ...

Exercise 1

- The columnar epithelium from the stomach resembles the columnar epithelium from the duodenum in many aspects. The columnar nature of the epithelium in both instances serves for increased protection of the underlying organs and organelles. The simple columnar epithelia found in the stomach and duodenum also contains the largest cytoplasmic volumes in comparison to all the other epithelia, housing organelle density and energy reserves suitable in the engagement of the most complex of secretory and absorption functions. The duodenum epithelia however, posses an extra microvillus which aids in increasing the surface area for absorption. The epithelia in the ...

Q1. Anaphylaxis identification, management and prevention

Anaphylaxis is referred to as an allergic reaction encompassing anaphylactic shock as a severe manifestation of the said allergic reaction according to Sinclair (2010). The average number of the people believed to be at risk of the aforementioned condition is about 1 to 15% if exposed to certain allergens. Experts believe that the estimated figures vary depending on the definitions of reaction (allergyfacts.org.au, n.d.). During an anaphylactic attack, the patient’s body reacts badly to allergens causing by food, venom, medication, and or insect bite. The body has a natural defense mechanism that fights the allergic ...

Introduction

Osmosis refers to the net water movement across a membrane, which is selectively permeable and the movement is driven by a difference in the concentration of the solutes on the opposite sides of the membrane. A selectively permeable membrane allows water to pass through without allowing ions or solute molecules to pass through. Other small molecules that are not charged are also allowed to pass through the membrane. Diffusion, on the other hand, refers to the movement of molecules in a random motion as a result of the kinetic energy and causes the molecules to have a net movement from areas where the particles ...

Crohn’s disease overview

Crohn’s disease (also called ileitis or enteritis) is a chronic, relapsing–remitting, non-infectious form of bowel disorder that mainly causes inflammation of the digestive tract, and is the general term for diseases that cause swelling in the intestines. This term has replaced older terms that include regional or terminal ileitis and granulomatous colitis; it doesn’t just imply any cause, site, or pathological response. The terminal ileum and the right colon are two sites that are most vulnerable, a close to this pathological disability can negatively influence multiple parts of the body, but this negative effect is connected with ...

Substance that ionizes in aqueous solution to produce hydrogen ion (H+) is defined as acid. It is proton donor and electron pair acceptor. Acid tastes sour, changes litmus from blue to red. Whereas, base releases hydroxyl ion (OH-) in their aqueous solution. It is proton acceptor and electron pair donor. It tastes bitter; changes red (acidified) litmus to blue. Salt is an ionic compound produced from reaction of an acid and a base. It is formed by the incomplete or complete substitution of the hydrogen ion (H+) of an acid by a basic radical. Three examples of acid used in ...

The model of complete replacement by Christopher Stringer and Peter Andrew states that 200,000- 150,000 years ago the archaic humans evolved to the modern humans in Africa and then later migrated to other parts of the world replacing the Neanderthals around 60,000 -40,000 years ago. This theory suggests that all people have an African ancestry (Kuklik & Henrika, 28).It also argues that all other forms of Humans like Homo erectus have gone extinct. It suggests that the developments seen in humans today are recent. Regional continuity model also known as multiregional evolution model by ...

The Digestive Tract

Part I: Parts of the Digestive Tract/System Part II Section A The Mouth The digestive tract starts at the mouth. This is the first step of digestion. When one takes the first bite, food begins the digestion process through chewing. Chewing breaks down the food into more soluble pieces. This also increases the surface area for which the digestive enzymes can work on the food in the latter stages of the digestion process.

Oesophagus

The oesophagus is located in the throat near the windpipe (trachea). This is the second stage of the digestion process. This part ...

Introduction

Social determinants of health can be described as the environmental conditions in which individuals live, work, learn, age and worship that significantly affect their levels of health, life quality, functioning, risks and outcomes. Among the most essential social health determinant is a healthy and safe physical environment and a good power, money and resources distribution. Water is indeed a very important resource and thus it often pops up whenever social determinants of health are being discussed. To explore this issue in more elaborate terms, it is good that we use a case study. Mountains beyond Mountains is a book by written by American ...

Introduction

In this paper, the pathopyiology of syncope is discussed with emphasis on Mr. Peter’s medical history and factors that could have contributed to his syncope. Further, the paper discusses the colonoscopy and its findings, his right hemi colectomy and the complications arising from his fall.

Pathopysiology of Syncope

Syncope is the transient loss of memory that occurs when cerebral blood flow falls to below half the normal value resulting in a brief period of inadequate oxygen, glucose and other nutrients supply to the brain tissues (Hainsworth, 2004). Syncope occurs rapidly, lasts for a short duration and the patient almost always recovers spontaneously. Syncope ...
