disease is commonly caused by a buildup of plaque which narrows the arteries and reduces blood flow causing platelets‚ red and white blood cells in the artery to clump together forming a blockage (DeSilva‚ 2013). Atherosclerosis is defined as ‘disease of the arteries characterized by the deposition of fatty material on their inner walls’ ("Oxford Dictionaries"‚ 2016) which eventually completely blocks the blood supply from the artery to the heart leading to a myocardial infarction and damaging the heart

to identify the blood in the brain of these postmortem apoplexy patients he also was the first to discover that some had blockages in their main arteries. These findings led to the renaming of apoplexy to cerebrovascular disease." (AHA) There are basically two types of strokes‚ ischemic stroke and hemorrhagic stroke. Ischemic stroke occurs when an artery supplying blood to the brain becomes blocked and suddenly stops or decreases the amount of blood to the brain which ultimately causes an infarction

Blood pressure refers to the force of blood pushing against artery walls as it courses through the body .Although many of you may not think that pressure of the blood system is not such a fascinating concept‚ it does play a very important role when taking vitals. Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats‚ it pumps out blood into the arteries.

known as blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA]‚ 2008‚ para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA‚ 2008‚ para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through your arteries at a higher pressure than normal” (AHA‚ 2006‚ para. 1).High blood pressure

common form of heart disease is Coronary disease (CHD)‚ and so this is the disease I will investigate. CHD refers to the build up of plaque in the arteries supplying oxygenated blood to the heart‚ also known as Atherosclerosis. The plaque is made up of cholesterol‚ fat and other substances found in the blood. When this build up of plaque occurs‚ the artery narrows‚ as shown in Figure. This will restrict blood flow to the heart‚ and so the heart will be deprived of oxygen and other essential minerals
