A patient Mr. Johan is admitted in a hospital. His major problem is pancreatitis. He is in severe form of pancreatitis. We have to manage his electrolyte imbalance, and there is a need to look after the food and electrolyte effect of the patient.

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 ...

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 ...

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 ...

A Journey through the Digestive, Circulatory and Urinary Systems

My Fantastic Voyage: A Journey through the Digestive, Circulatory and Urinary Systems
My journey begins with the ingestion of a cheeseburger, fries, and root beer by a 55 year old man. I begin my trip in the gastrointestinal tract. While in the mouth, the food is masticated by the teeth and combined with saliva to moisten the bolus and begin digestion. Salivary amylase begins the breakdown of starches into smaller sugars and salivary lipase begins breaking down the fats (“Saliva,” 2013). We are then swallowed and peristalsis moves us down the esophagus towards the stomach (University of Leicester, 2001).

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 ...

Digestion in human beings and other animals is overly dependent on the action of enzymes; in their basic form, enzymes are protein materials that act as catalysts with the ability to produce certain chemical changes. Digestion of food substances usually begin in the mouth. The glands in the mouth produce enzyme salivary amylase (which acts on starch changing it into sugar) and lingual lipase (which kicks off the digestion of lipids) (Chiras 109). The stomach n its part, produces two enzymes, pepsin that breaks down proteins into peptides (Chiras 109). While there are no enzymes produced in the large ...

Trace elements refer to chemicals that form parts of important enzymes found in the body of a living organism occurring in minute amounts, less than 0.1% by volume (Anonymous, 2015). Trace elements are available in the natural environment and play a critical role in the survival of all living organism. Individual elements attract molecules from the environment and convert them to various products needed by the organism. Examples of trace elements are iron, copper, zinc, manganese, boron, molybdenum, iodine, cobalt among others. However, the following paper analyzes only three of these trace elements namely, copper, iron, and zinc.

The cardiovascular system consists of the heart and blood vessels that get bifurcated further into veins, capillaries, and arteries. Lungs and airways make the most of the respiratory system; these, coupled with other structures help in the inhalation and exhalation process. Muscles are the other part of the system that helps the lungs to expand and contract in sync with inhalation and exhalation.
Absorption starts in the body after the food is broken down into its building blocks. The process of absorption starts in the abdomen with the direct consumption of simple substances( e.g. water and alcohol) into the ...

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 ...

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 ...

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 ...

Biomolecules serve different functions in a cell. The three major classes of biomolecules in the cell are: proteins, nuclei acids and carbohydrates. These molecular structures serve nearly similar functions in most organisms. Though the function of protein in forming cell architecture, signaling and communication is well known, little is known about the role of carbohydrate in communication. Nevertheless, it goes un-denying that carbohydrates are indispensable for cellular communication and signaling, just like proteins and nucleic acids. The paper titled, Carbohydrates in Cell Recognition, by the authors Nathan Sharon and Halina Lis, is a good review that elucidates the significance ...

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 ...

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 ...

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 ...

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 ...

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 ...

Abstract

Colon is the part of the large intestine and its cancer is one of the important problems of modern society. Several factors can result in the development of colonic cancer. These factors may include non-modifiable types of risk factors as for example growing age, gender, race or ethnicity, and hereditary factors, and modifiable types of risk factors as for example obesity, poor diets, tobacco use, alcohol intake, reduced physical activity and sedentary life. Sedentary behavior is an important risk factor for modern life. It can result in obesity, insulin problems, and diabetes, which are found to be involved ...

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 ...

Background information on Giardia

Giardia is luminal intestinal flagellated protozoan parasite. Giardia lamblia( also known as G. intestinalis or G. duodenalis) is the most common species that usually exhibits a typical fecal-oral lifecycle. Giardia lamblia) colonizes the upper portions of the small intestine and is the most common protozoan isolated from human stools. The prevalence is estimated at 200 million clinical cases per year [ CITATION Annd3 \l 1033 ].
Giardia lamblia exists in two forms, an active form called a trophozoite, and an inactive form called a cyst. The active trophozoite attaches to the lining of the small intestine with a "sucker" and is responsible for causing ...
