Atherosclerosis is a cardiovascular disease of the walls of the artery that comes as a result of accumulation of fatty deposits on walls of the artery leading to an impairment of the flow of blood (Weber & Soehnlein, 2013). With in mind that cardiovascular diseases cause deaths and morbidity in several countries, atherosclerosis can be viewed as a serious disease particularly with regards to the ever increasing cases of obesity.
Notably, there is an apparent relationship between atherosclerosis and heart attack; atherosclerosis most commonly leads to heart attack. The understanding of the relationship between atherosclerosis and heart attack can be best understood ...

The cardiovascular system consists of blood, the heart, and the circulatory system, which includes veins, arteries, and capillaries. The function of these organs is to transport oxygen from the lungs to cells throughout the body. Each organ system in the body is essential in providing homeostasis in the human body. However, the actions of the cardiovascular system are critical to human life. Many physicians, scientists, and other professionals dedicate their life to the understanding of the cardiovascular system and its diseases so that people can live longer and more productive lives. This paper will discuss the general anatomy of ...

Introduction

The body is on an ongoing and continuous quest to maintain an environment characterized with equilibrium. Scientifically, this state is called homeostasis. It is the body’s internal mechanism that is meant to make the person survive, despite the numerous internal and external changes it may encounter. The body of a person who was acutely exposed to a colder than usual environment would, for example, react by preserving the heat that is currently stored in and generated by the body—something which can be done in a lot of ways such as, but may not be limited to vasoconstriction, ...

The cardiovascular system (both the heart and the circulatory system) is defined as “the network that delivers blood, oxygen, and nutrients to the body's tissues in conjunction with the respiratory system” (Anonymous, 2012). The circulatory system consists of a vast network of tubes that carries the blood to and from all parts of the body. The heart, lungs, arteries, arterioles (small arteries), and capillaries (very tiny blood arteries, also called vessels) carry oxygen- and nutrient-rich blood away from the heart to the rest of the body. The veins and venules (small veins) carry oxygen- and nutrient-depleted blood back to the ...

Cardiovascular system

The cardiovascular system is also known as the circulatory system, and it is the body’s transportation system that comprises the heart, blood vessels, and blood. The system does the work of transporting oxygen, hormones, cellular waste products and nutrients to all the parts of the body. The use of blood transports all the products, and it is approximated that the body of an adult makes use of five liters of blood to transport the products from one part to the other. Blood is pumped from the heart through the arteries then gets into body tissues through capillaries (Inner ...

Absorption

Absorption is the process through which biomolecules traverse through the GI tract into the circulatory system. Digested food gets absorbed in the small intestinal lumen through four processes, which include active transport, passive transport, endocytosis and facilitative diffusion. The efficiency of absorption of nutrients may be attributed to the large surface area lined up with hair like projections and microvilli cells .

Excretory System

Excretion is the mechanism through which waste products and eliminated from the body and osmotic pressure and homeostasis is achieved in the body . The process of excretion in the body takes place in three stages: filtration, reabsorption and ...

Oxygen is essential to the survival of all body cells. The supply of oxygen to those cells is maintained via the circulatory system. The circulatory system is an integral part of the cardiovascular system which is maintained by the heart, blood vessels and blood. The three main subtypes of circulatory systems that occur in humans are the systemic circulation, pulmonary circulation and coronary circulation. All the three types of circulation are dependent on one another to maintain the supply of oxygen to and removal of carbon dioxide from the body tissues.

Pulmonary circulation serves as the link between the ...

Cardiovascular diseases are the illnesses of heart and blood vessels (arteries and veins) (World Health Organization). In fact, there are many different diseases of the cardiovascular system, but I would like to highlight the most common.

Arrhythmia

Arrhythmia is a condition in which the frequency, rhythm and sequence of heart contractions are violated. The symptoms occur because of various congenital anomalies, acquired diseases of the cardiovascular system, as well as under the influence of vegetative, hormonal or electrolyte disturbances and as a result of the adverse drug action.
Violated heartbeat, weakness and fainting are frequent companions of arrhythmia. The diagnosis ...

Red blood cells take approximately 120 days to be produced. The process of its production is called erythropoiesis and the place of production is myeloid tissue. For the formation of red blood cells, the haemocytoblast must be present. The existence of Multi-CSF causes the haemocytoblast to progress into progenitor cells. The progenitor cells, on the other hand, will form other cells. This cell may also develop into proerythroblast when EPO is present. Proerythroblast forms basophilic erythroblast which will in turn develop into polychromatophilic erythroblast, followed by normoblast which develops into reticulocyte which eventually becomes erythrocyte. All these developments must ...

The term martial art is used to mean traditions or coded systems used in combat. There are many forms of martial arts such as Karate, kung fu, muay Thai, aikido, judo, taekwondo, hapkido, krav maga and jujutsu. Traditionally, martial arts originated from eastern Asian countries. The communities in the eastern Asian nations considered some of the arts to be part of their culture, background and religion. However, martial arts have spread all over the world and are practiced for a wide range of objectives. Some people practice martial arts for commercial purposes, competition, personal fitness, self defense or physical and ...

Abstract

Traumatic brain injury is an acquired injury to the brain that results from an external blunt or penetrating force to the head while; intentional hypoxia is the loss of oxygen supply to the brain which leads to a continuum of injury severity. A review of current literature on this topic suggests that comparisons can be readily drawn between traumatic brain injury and hypoxic brain injury in a rehabilitation setting. Even so, diagnosis of hypoxic brain injury and traumatic brain injury is essential in providing guidance on decisions of treatment. Treating intentional hypoxia, however, involves an establishment of the desired ...

The functioning of the cardiorespiratory system

When one breathes in air via the nose and mouth, this air travels to the lungs. Oxygen that is contained within the air gets absorbed into the bloodstream through the lungs. The heart then pumps oxygenated (oxygen-rich) blood via the network of arteries (blood vessels) to the body tissues everywhere around the body. These tissues include organs (such as kidneys and livers), nerves and muscles. Upon arrival at the various tissues, blood releases the carried oxygen. This oxygen is required by body cells to function. Cells dispatch waste products like water and carbon dioxide, which are then absorbed and ...

The cardiovascular and respiratory systems are largely responsible for the transportation of oxygen and carbon dioxide through the body. Respiration consists of both inspiration and expiration. These actions are the methods by which essential oxygen is exchanged with harmful carbon dioxide. While oxygen is brought into the lungs during inhalation to be processed throughout the body, carbon dioxide is brought during exhalation to be removed from the system entirely. Once the oxygen has reached the lungs it is taken up by the bloodstream in order to be distributed to the various cells that require a constant exchange of nutrients ...

The Women’s Health Initiative is a long-term national health study that started in April 1991. WHI is a result of a growing scientific interest and an urgent need for better understanding of the nature of women’s diseases. The entire project employed 161, 808 women of 50-79 years of age, and therefore, became one of the most far reaching women’s health experiments that have ever been taken in the U.S. The clinical trial consisted of three parts such as hormone therapy, dietary modification and calcium/vitamin D supplements. They were dedicated to the issue of preventing cancer, osteoporosis ...

Cadburyoma: A chocoholoma syndrome

Maria suffers from a rare syndrome termed Cadburyoma. It is a disease caused by consumtion of cadburo disease. It initially affects the cardiovascular and gastrointestinal system of the body. Further on when the disease reaches its peak level, neuronal problems arise. Cadburyoma is seen in both males and females and is more prevalent in urban lifestyle.

History

It was first coined by a Lyndon F, a scientist working in the Ohio state university. He observed that patients with Cadburyoma had various cardiovascular problems. He noticed that these patients suffered from varied ailments in the cardiovascular system which included: arrhythmia, angina pectoris, hematoma, valvulitis and ...

Question 1: Pathophysiology of Mr. Jensen’s post-operative hypovolemia

Hypovolemia is a surgical condition that indicates the rapid fluid loss that may result in organ failures. The outcomes of the hypovolemia are mostly due to insufficient circulating volume or scarce perfusion. Often hypovolemia is secondary to hemorrhage the reason of which includes severe internal or external blood loss and GI, thoracic and abdominal bleeding maladies (Devitt, 2001).
Hypovolemia involves significant fluid loss other than blood that can be further accompanied by refractory gastroenteritis and widespread burns. Hypovolemia may develop in post-surgical incidence, bone fracture, due to ...

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 ...

What explains the decline in mortality in developed countries? Are there lessons to be learned in relation to the poor in developing countries today?
I. Introduction

A. General Information

In general, the mortality level is deservedly considered to be among one of the characteristics that reveals both economic and social health of the certain state and that clearly describes the effectiveness of the policies that governments get used to adopt. In this context, the most significant particular demographic indicators are commonly the following:
1) Infant mortality rate;
2) Maternal mortality rate;
3) Mortality amid able-bodied citizens;
4) Mortality caused by external factors;

Measuring Heart Beats (ECG)

The heart rate of an individual has been defined as the number of times a heart beats every minute (Edlin and Golanty, 2016). When a heart beats, it pushes a volume of blood into the circulatory system. At some points in the circulatory system where the blood flows near the skin surface, one can feel blood flowing as a result of heartbeat. It is at these points where heart rate is measured. Usually, the heart rate of a person is measured at the carotid artery in the neck, radial artery located in the wrist just below the thumb, or ...

What is the Pathophysiological Effect of Stress on the Immune System?

Stress is a feeling of anxiety and pressure, which the body feels in response to any external demand that cannot be easily coped with. It can develop out of both positive as well as negative experiences. Stress can be emotional or psychological, such as the loss of a dear one or after losing one’s job or anything that affects a person sentimentally. Fatigue and getting overworked are also stressful situations that cause worry, and a person feels ‘stressed.’ Stress can affect the body in many ways, and it can lead to sickness, tired, distract a person and inhibit ...

The Body as a Complex Problem

The body harbours all the characteristics of a complex problem. For example, it is a complex system made up of many interconnected components; the legs, the arms, the ears, eyes, the head, the mouth and the waist are some of the distinct parts of the body. The enormity of body parts creates the idea of chaos; all these parts perform different functions, and it is difficult to determine the long-term behaviour of each one of them. However, it is puzzling to note that with so many parts performing different functions, the body appears well-coordinated unless problems arise within any of the ...

Comparison of flight mechanic propeller driven air planes and birds

Both birds and airplanes have a requirement that they must overcome the force of gravity in order to make flights. Due their weight difference, airplanes and birds differ in power requirement for flying. The power to bring balance between the lift and gravity, drag and thrust such that any flying object can fly comfortably varies as power the weight of these objects. Depending on the power capability of birds and airplanes there are limits for weight requirements for these objects. Airplanes require powerful engines to fly their heavy weight. Most commonly heavy airplanes use jet engines to fly the heavy ...

Hypertension, or high blood pressure is a measurement of the force of your blood against your arteries as your heart pumps it through your body. It is generally indicated by two numbers; the systolic and the diastolic blood pressures. Normal blood pressure is less than 120 over 80 (120/80 mmHg). Pre-hypertension is when blood pressure falls between 120/80 mmHg but less than 140/90 mmHg. Blood pressure levels of more than 140/90 mmHg is considered Hypertension. . Some contributing factors that increase the risk the risk of developing high blood pressure are age, ethnicity and family history. These factors are not preventable ...

Lymphatic System

The lymphatic system is an extensive one way drainage system, which is made up of lymphatic vessels, lymph nodes, the spleen and the thymus. It is part of the circulatory system. The lymphatic vessels have three main functions. Lymphatic vessels drain water and plasma protein that leaks from the capillaries and return them to the circulatory system, they carry fats absorbed in the small intestines to the blood, and transport cellular remains, pathogens, and foreign cells to the lymphoid tissues where white blood cells annihilate them (Starr. C, Targgat, Vers & Starr. L, 2012). Lymph nodes act as sites for ...
