  • Coronary Arteries

    2083 Words  | 9 Pages

    heart’s main function is to keep blood continually circulating throughout the body. Arteries are the vessels that supply the body with oxygen rich blood; on the contrary the vessels that return blood to the heart are called veins. Like any other muscle in the body, the heart depends on a steady supply of oxygen rich blood. The arteries that carry this blood supply to the heart muscle are called coronary arteries. Sometimes these blood vessels can narrow or become block by deposits of fat, cholesterol

  • Explain The Function Of The Pulmonary Artery

    515 Words  | 3 Pages

    pulmonary artery is to pump deoxygenated blood to the lungs from the heart to become oxygenated. The pressure inside the pulmonary artery is very low, although blood here is at a slightly higher pressure than the blood in the pulmonary vein, and this is reflected as the walls of the artery are significantly thinner than the walls of a corresponding artery, for example, the aorta. The walls of the pulmonary artery contain a large amount of elastic fibres in order to maintain the shape of the artery. The

    modality is the most accurate in vertebral artery dissection diagnosis? Pei Wen Tammy Kwa, Sarah Moore, Paul Ryan, Kate Somers Introduction An arterial dissection is said to occur when the structural integrity of an arterial wall is compromised, permitting blood to collect between layers of the vessel wall to form an intramural haematoma. Arterial dissection is a common cause of stroke in the young, although it may occur at any age. Vertebral artery dissection (VAD) most often occurs in the cervical

    Explain the function of the heart, and the structure of the arteries veins and capillaries The heart is a key muscular organ, and is controlled by the autonomic nervous system. It transports blood to the body’s tissues via the circulatory system; blood provides the body with oxygen, nutrients and also assists in the removal of carbon dioxide and metabolic wastes, hormones are transported throughout the body by plasma. Arteries, arterioles, veins, capillaries and valves, are the blood vessels

  • Artery Disease Research Paper

    1904 Words  | 8 Pages

    Coronary Artery Disease is a condition that is caused by a thickening of the inside walls of the coronary arteries. It is disease is also known as CAD, Arteriosclerotic or Coronary Heart Disease. Coronary heart disease is one of the most common heart diseases in the United States. The risk of this disease increases with increased age. The coronary arteries are major blood vessels that supply our hearts with blood oxygen, and the nutrients we need to survive. An artery has a smooth inner lining

  • Essay On Coronary Artery Disease

    922 Words  | 4 Pages

    Coronary artery disease is usually caused by atherosclerosis. Cholesterol and other fatty substances accumulate on the inner wall of the arteries. This attracts fibrous tissue, blood components, and calcium, which harden into flow-obstructing plaques. If a blood clot suddenly forms on one of these plaques it can convert a partial obstruction to a total occlusion. When the blockage is temporary or partial, angina (chest pain or pressure) may occur. When the blockage completely and suddenly cuts off

  • Essay On Peripheral Artery Disease

    845 Words  | 4 Pages

    What are the symptoms of peripheral artery disease? Snippet: Peripheral arterial disease (PAD) is a condition, in which a build-up of fatty deposits (atherosclerosis) in the arteries leads to the narrowing of the peripheral arteries and reduce blood flow to the legs, stomach, arms, and head. According to statistics, both men and women are affected equally by this condition. However, the prevalence increases as one age. The characteristic symptoms of PAD include-fatigue, heaviness, tiredness, or

  • Splenic Artery Aneurysm Case Study

    763 Words  | 4 Pages

    Splenic Artery Aneurysm Splenic artery aneurysm is the third most common aneurysm in the abdomen and the most common type to affect the internal organs. The spleen is an abdominal organ that forms part of the immune system. It has a large artery that supplies blood to it. When a portion of this artery balloons or widens because of weakness in its walls, an aneurysm develops. Other more common intra-abdominal aneurysms affect the aorta and the iliac arteries. Part 1: Are There Any Symptoms of Splenic

    1. Coronary Artery Disease: Coronary artery disease develops when your coronary arteries — the major blood vessels that supply your heart with blood, oxygen and nutrients — become damaged or diseased. It is a result of plaque buildup in your coronary arteries -- a condition called atherosclerosis -- that leads to blockages. The arteries, which start out smooth and elastic, become narrow and rigid, restricting blood flow to the heart. The heart becomes starved of oxygen and the vital nutrients it

  • Coronary Artery Disease Case Study

    Coronary artery disease (CAD) is the leading cause of death worldwide ( Reddy 1993; Lloyd-Jones et al. 2009). According to WHO, 23.6 million deaths each year by 2030 are caused by cardiovascular disease. In Malaysia, diseases of the circulatory system are the leading cause of death in Ministry of Health (MoH) Hospitals in 2012. 40, 000 new cases per year for 28 million people in this country while for number of CAD cases for young people which is below 45 years old is increased every year. 95 %

    The presence of any risk factor is thought to double the relative risk for developing atherosclerosis/coronary artery disease and acute myocardial infarction. These risk factors include: • High Blood Cholesterol – An elevated lipid level is major component of atherosclerotic plaque buildup which causes the development of an infarction. • Diabetes Mellitus – Patients

  • Aortic Arches In Vertebrate Analysis

    Aortic arches are also called as pharyngeal arteries. They are vascular structures that emerge from the ventricle of the heart. There are 6 pairs of these arches in embryonic stages which give rise to several major arteries later. They arise from the aortic sac and are present on the ventral and dorsal aorta. As discussed earlier that there are 6 pairs of aortic arches present in embryonic stages giving rise to several arteries are as follows: Arch 1st and 2nd: The first and second arches

    placement is surgery to place a small metal tube (stent) into a blood vessel in the thigh. The stent is placed in a blood vessel that moves blood from the heart to the leg (iliac artery). The purpose of the stent is to keep the artery open. You may need this procedure if you have a narrow, blocked, or damaged iliac artery that does not provide enough blood flow to the leg.

    blockage of one of the small arteries deep in the brain. When one of these arteries is blocked, parts of the brain do not get enough oxygen and die. Lacunar stroke is a medical emergency that must be treated right away. A lacunar stroke is a type of ischemic stroke. An ischemic stroke is caused by a blood clot blocking an artery. What are the causes? A lacunar stroke is caused by a blood clot blocking blood flow in an artery in the brain. The blockage is the result of the arteries becoming more narrow due

    Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are; lumen, endothelium, smooth muscle and connective tissue. LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure. ENDOTHELIUM=forms the inner layer of an artery wall, also

    you body correctly. WHAT IS THE ISCHEMIA DISEASE Ischemia Heart Disease or Coronary Heart Disease is the narrowing of the blood vessels that supply the heart with blood and oxygen. These Arteries Include: 1. Left Anterior Descending Artery 2. Left Circumflex Artery 3. Right Coronary Artery. When these arteries are narrowed, the blood flow and oxygen circulation is forced to stop causing your body to have less movement. This is a very dangerous disease due to the fact that when the blood clot occurs
