and right ventricles. Venous and arterial compliances are modeled by air and water tanks, while tygon tubes are used to model flow resistance of the venous, arterial flows. The variation in system resistance characteristics under different cardiac pressure and flow conditions are modeled by a tuning clamp. The mock circulatory loop was tuned to simulate several pathological and normal cardiovascular activity state of a person unlike the older mock circulatory loops. Different human activity rates like

blood vessels are three kinds of blood vessels: arteries, veins and capillaries. The heart is the most important organ of the cardiovascular system, it is the most vital organ in the human body, and its function is to circulate the blood acting as a pump. The arteries are blood vessels that leave the heart and carry the blood to the different organs of the body. The veins are larger microscopic blood vessels than the arteries that run superficially to the skin. The capillaries are thin vessels that

percent of deaths. Hemorrhagic strokes are either brain aneurisms that have busted, or perhaps a weak blood vessel that has leaked. The blood from these bursts or leaks usually spills into or around the brain creating

class of diseases that affect the heart and the blood vessels. The blood vessels are the arteries, capillaries, and the veins. The various diseases that fall under the term cardiovascular disease include coronary artery disease, heart attack, heart failure, high blood pressure and stroke. The more common form of cardiovascular disease is Coronary Heart Disease or Coronary Artery Disease. The Coronary Artery

Unit 1 - Assignment 2: Cardiorespiratory System The Cardiovascular System The cardiovascular system is an extremely complicated network of three main parts the blood, the heart and the blood vessels. Basically the job of the cardiovascular system can be explained in two parts, the first is to remove by products from tissues and the second is to deliver nutrients to the body. The heart is situated right in the very centre of the cardiovascular system, the heart summed up is simply a four chambered

Coronary artery disease Coronary arteries are blood vessels that carry blood to the heart muscle. The coronary artery disease (also called CAD, for its acronym in English) or coronary heart disease is caused by a thickening of the inner walls of the coronary arteries. This thickening is called atherosclerosis. A fatty substance called plaque builds up inside the thickened walls of the arteries and obstructs or delays the flow of blood. If the heart muscle does not receive enough blood to function

Carry Oxygenated Blood (except for Pulmonary Artery) Smallest blood vessel Have a relatively wide lumen Have a relatively narrow lumen Exchanges oxygen and carbon dioxide Have relatively less smooth muscle and elastic fibres Have relatively more smooth muscle and elastic fibres So small that Red Blood Cells can only travel through in single file Transports blood under a lower pressure (than arteries) Transports blood under high pressure (compared to veins) Walls are only one cell layer thick (allowing

Hypertension is a common health problem especially among people over age of 60 years. This disease is diagnostic when a patient blood pressure is more than 140 to 159 over 90 to 99. Blood pressure refers to the pressure that blood applies to the inner walls of the Diabetes is an endocrine system disorder that occurs when the body is unable to control or balance the amount of sugar in blood and within bodily tissues. You know that the human body is like a machine, with organ systems that are specialized

heart into the periphery resulting in the pressure of the blood in the arteries being high. Where as, the veins transfer blood towards the heart. Arteries carry oxygenated blood distributing it in the periphery as the pulmonary artery moves deoxygenated blood into the lungs for purification. The wall of an artery consists of three layers machining it thicker than veins. The elasticity within the layers of the muscle allows arteries to handle great pressures of blood within it. The thickest layer is

system. They have one of the most powerful hearts of all mammals and there blood pressure is double the amount of most mammals! Since the Glamingos neck is so long the heart must work very hard to pump blood from the neck to the brain. In the upper part of the neck there is a complex pressure regulating system that maintains blood flow when they bend down to drink water. In their brain there is an elastic blood vessel that connects one way valves in the neck to prevent the head from swelling when
