High or Low Blood Pressure? Purpose: The purpose of this experiment is to compare blood pressure as related to gender and athletic status. Hypothesis: I predict that males have a higher blood pressure than women and athletes have a higher blood pressure than non athletes Background Info: Blood pressure is the amount of force that blood pushes against the inside walls of blood vessels as it passes through. This pressure

Coronary Heart Disease (CHD) is a disease in which waxy substance called plaque builds up inside the coronary arteries. These arteries are used to supply oxygen-rich blood to your heart‚ so if they’re continuously blocked up‚ it can be very dangerous. If the flow of this oxygen-rich blood is reduced or blocked‚ a heart attack can occur. It is the number one cause of death in the United States for both men and women and although this type of disease mainly happens at an older age‚ it can happen

such as chest pain and pain in the left arm. Heart failure’s definition is obvious from its term. Heart stops working due to lack of oxygen(1). Lack of oxygen in the artery that is coming from lung to the heart. This artery called coronary artery. The lack of oxygen in this artery is due to blocking of this artery. In this case‚ heart starts to adapt this condition by many ways. First‚ heart champers enlarge‚ heart contracting cells get bigger‚ and heart pumps faster. All these adaptive

increased blood pressure which in turn‚ leads to risk of damage to the artery walls. This is because damaged artery walls have an increased risk of atheroma formation‚ which‚ as a result‚ causes a further increase in blood pressure. Atheroma leads to an increase in the formation of aneurysms. As a result of high blood pressure‚ aneurysms plaques damage and weaken arteries‚ which means that blood flow pushes the inner layers of the artery through the outer elastic layer to form a balloon-like swelling.

meal‚ exposure to extreme temperatures‚ and smoking may trigger angina attacks. Unstable angina is often caused by blood clots that partially or totally block an artery. Larger blockages may lead to heart attacks. As blood clots form‚ dissolve‚ and form again‚ angina can occur with each blockage. Variant angina occurs when an artery experiences a spasm that causes it to tighten and narrow‚ disrupting blood supply to the heart. This can be triggered by exposure to cold‚ stress‚ medicines‚ smoking

Introduction Some 7 million Americans suffer from coronary heart disease (CHD)‚ the most common form of heart disease. This type of heart disease is caused by a narrowing of the coronary arteries that feed the heart. CHD is the number one killer of both men and women in the U.S. Each year‚ more than 500‚000 Americans die of heart attacks caused by CHD. Many of these deaths could be prevented because CHD is related to certain aspects of lifestyle. Risk factors for CHD include high blood pressure

lack of physical activity‚ and smoking. Here‚ we will discuss those risk factors‚ and discuss ways to diminish those risk factors. Heart disease or coronary artery disease is caused by a blockage in the blood vessels that supply the heart. The blockages are caused by plaque which contains cholesterol in large amounts that adhere to the artery walls‚ and build up until the flow of blood is impeded. That impairment causes a heart attack which causes portions of the heart to die. If the blockage‚ or

Angioplasty: A stent is a mess tube used to treat narrow or weak arteries (blood vessels that carry blood away from the heart to other parts of the body). The stent is placed in the artery as part of an Angioplasty procedure. Angioplasty restores blood flow into narrow or blocked arteries. The stent helps to support the inner wall of the artery after the angioplasty. Doctors also place stents in weak arteries to improve blood flow and prevent arteries from bursting. Valve Replacement If one or more of

Atherosclerosis This is an ailment connected to the arteries. The arteries are blocked by deposits of cholesterol and fat-absorbing cells. When this happens‚ the blood supply to the different parts of the body is affected. The worst comes when an artery supplying blood to the brain is blocked because it causes stoke and may result to permanent disability or death. Studies show that atherosclerosis is caused by a lot of factors such as cigarette smoking‚ obesity‚ high blood pressure‚ high cholesterol
