blood, this eventually leads to the buildup of plaque in the walls of arteries in the body; this is what causes blockage in the blood vessels and prevents blood flow and as a result prevents oxygen flow throughout the body as well. The buildup of plaque in a patient’s blood vessels is where the real danger occurs, because this can lead to blood clots in the vessels which then can lead to heart attack or having a stroke. The symptoms for heart attack are different between the sexes. Both male and

spilling out. The Prefix ‘peri’ means around, or on the outside of the tissue. Retinal vascular sheathing is “sheathing or cuffing of blood vessels and vitreous cells”. The swelling or ‘cuffing’ of blood vessels in the retinal layer is a serious condition and is often associated with vasculitis. Finally, a retinal hemorrhage is “abnormal bleeding of the vessels in the retina”2. Retinal hemorrhages can be caused for a variety of reasons such as injuries like forceful blows or accidents and falls, as

Cardiovascular system consists of the heart and it’s associated blood vessels. “Main functions of the cardiovascular system include the supply of oxygen and nutrients to all cellular tissues in the body while also removing metabolic wastes such as carbon dioxide” (Collins, 2013 p. 169). The heart is a four-chambered organ with two superior atria and two inferior ventricles. There is four valves located in the heart each function to prevent the backflow of blood into either atria or ventricular chambers

local response consist of vascular response and cellular response. shortly after the injury has occurred there is brief construction of blood vessels which may last for five minutes. this is replaced by dilatation if the vessel occurring within thirty minutes of the injury. the dilatation of the blood vessels account for increased blood supply -(hyperaemia) and increased permeability of the venular and the capillaries. Exudation (escape) of some cells and fluid (plasma) into

almost double the risk compared to Caucasians. High blood pressure is one of the leading causes of stroke. As many as 50 million Americans have high blood pressure and only 31 % know they have it. High blood pressure puts unnecessary strain on blood vessel walls causing them to thicken and deteriorate. Smoking almost doubles your risk of ischemic stroke and increases your risk of hemorrhagic stroke by 3.5 percent (AHA). High alcohol content can lead to stroke. Stroke 4 While studies show that a small

Haemodynamics of large vessels by Phase Contrast MRI Cardiovascular diseases The cardiovascular system is the network of blood vessels with the major role in transportation of oxygen and nutrition to the tissues and the waste products from organs and tissues. The diseases of the cardiovascular system, either acquired or congenital, may result in ischemia or undersupply of major organs, which would be a threat to the overall health of an individual. Events caused by cardiovascular diseases are the

formation of new blood vessels. Our body exactly filled with blood vessels. End to end, they would circle the earth twice. The smallest ones are capilleries. Usually, they save our lives but sometimes they cause dead. Blood vessels don't normally grow in adults. We get most of them in the womb, except in some special conditions like after injury. When we get an injury, blood vessels must to grow under the scab to heal wound. Endotelial cells line the inside of the blood vessels and they begin to migrate

Chapter 19 The Cardiovascular System: Blood Vessels: Part A Blood Vessels Delivery system of dynamic structures that begins and ends at heart Arteries: carry blood away from heart; oxygenated except for pulmonary circulation and umbilical vessels of fetus Capillaries: contact tissue cells; directly serve cellular needs Veins: carry blood toward heart Structure of Blood Vessel Walls Lumen Central blood-containing space

• Capillaries, which are numerous fine vessels with thin walls that provide a large surface area where the exchange of substances occurs which connects the arteries and the veins. Blood – Which is the circulating fluid and is highly specialised for transport and immune defence. Stroke, also called Apoplexy – Disease A sudden impairment of brain function which is the result from a vast reduction in blood flow to some parts of the brain or from intracranial bleeding. Causes of a Stroke Ischemic

and other animals, which pumps blood through a 60,000 mile of blood vessels of the circulatory system. Blood moves through many tubes called arteries and veins which together are called blood vessels. It weighs between about 280 to 340 grams in men and 230 to 280 grams in women. Size of the heart is about your fist. Pumping of the heart relies on a complicate system of muscle which is called myocardium, valves, coronary vessels, the conduction
