Hypertension Hypertension is high blood pressure. Blood pressure is the force of blood pushing against the walls of arteries as it flows through them. Description As blood flows through arteries it pushes against the inside of the artery walls. The more pressure the blood exerts on the artery walls, the higher the blood pressure will be. The size of small arteries also affects the blood pressure. When the muscular walls of arteries are relaxed, or dilated, the pressure of the blood

Blood Pressure Homeostasis Homeostasis in the ability of the body to keep an internal environment that is constant, regardless of outside influences. Blood pressure remains within normal limits through the utilization of both rapid and slow mechanisms. Working together, the mechanisms strive to maintain an approximate blood pressure of 120/80 mm Hg. The baroreceptor reflex is one of the most important fast acting homeostatic mechanisms involved in regulating blood pressure. This contains receptors

project – Essay Supporting the article: According to the popular science theory of cholesterol, foods that are rich in animal fat and cholesterol can cause the artery walls to thicken, thus impairing blood flow. This condition is called atherosclerosis. But the question is, is it the high cholesterol that causes the artery walls to thicken, thus creating the potential for a heart attack? LDL is a lipoprotein that enables transport of lipids through the bloodstream. LDL has been regarded as a

ischaemic and haemorrhagic. An ischaemic stroke happens when there is a blood clot which stops blood and oxygen from travelling to the brain. The blood clots are created when plaque narrows your arteries and reduces blood flow which is called atherosclerosis. Another cause is by irregular heartbeats as it can lead to the blood clots leave the heart and block the blood supply which leads to the brain which stops the oxygen. Haemorrhagic strokes are less common than ischaemic strokes. They happen when

Disease. Cardiovascular disease is a condition that affects the vascular system which is the blood vessels as well as the heart. To understand the cardiovascular system it is consists of many different illnesses such as coronary heart disease, atherosclerosis, and congestive heart disease. There is three main causes to cardiovascular disease are heart attacks and heart disease. The third is an individual that has high blood pressure. When arteries become narrower as the person becomes older, the

Review the basics of cardiovascular disease and atherosclerosis. Be ready to identify the risk factors for cardiovascular disease (especially diet-related risk factors!)

Heart Disease. Overview. Heart disease (also called cardiovascular disease) is a class of diseases that involve the heart, the blood vessels (includes arteries, capillaries and veins) or both. The accumulation of plaque causes the blood vessels (veins) to narrow, which reduces the ability of blood to flow in and out of the heart. Cardiovascular disease is a general term that includes many types of heart disease, such as heart attack and stroke. Cardiovascular disease is the leading cause

women and men. (Medline Plus, 2014). CAD is known to happen when the arteries that supply the blood to the heart can become hardened and narrow. The build up is due to cholesterol and plaque that gets caught on the inner walls and it is called atherosclerosis. This makes it hard for the blood to flow through the arteries. When this happen it a person can have chest pain or lead to a heart attack from a blood clot. (Medline Plus, 2014). CAD affects both men and women and it can be hereditary. This
