Coronary Heart Disease Coronary heart disease (CHD) is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. When plaque builds up in the arteries‚ the condition is called atherosclerosis (ATH-er-o-skler-O-sis). The buildup of plaque occurs over many years. (nhlbi.nih.gov) CHD AND TREATMENTS: CHD is the most common type of heart disease. In the United States‚ CHD is the #1 cause of

old Caucasian female who had a partial obstruction in the carotid artery on the right side for over two years and had a stroke in the right hemisphere 6 months ago. The main common carotid artery splits into the external carotid artery and the internal carotid artery. The external carotid artery supplies blood to the exterior features outside of the skull‚ primarily the exterior of the face and the neck. The internal carotid artery supplies blood to the interior of the skull‚ including the anterior

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.

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

08/12/13 1. MEDICAL TERMINOLOGY Aneurysm (AN-ū-rizm) A thin‚ weakened section of the wall of an artery or a vein that bulges outward‚ forming a balloonlike sac. Common causes are atherosclerosis‚ syphilis‚ congenital blood vessel defects‚ and trauma. If untreated‚ the aneurysm enlarges and the blood vessel wall becomes so thin that it bursts. The result is massive hemorrhage with shock‚ severe pain‚ stroke‚ or death. Treatment may involve surgery in which the weakened area of the blood

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

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

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

ANATOMY AND PHYSIOLOGY Chronic Kidney Disease Cardiovascular System The cardiovascular system is sometimes called the circulatory system. It consists of the heart‚ which is a muscular pumping device‚ and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body.
