  • 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

  • Vertebral Artery Dissection Essay

    1558 Words  | 7 Pages

    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

  • Coronary Artery Disease Continuum

    432 Words  | 2 Pages

    The pumping ability of the heart is compromised by a continuum between coronary artery disease, myocardial ischemia, and myocardial infarction. This paradox deprives the heart of blood-borne oxygen and nutrients. Coronary artery disease (CAD) is the earliest of the continuum and consists of any disorder that narrows or blocks the coronary arteries. Atherosclerosis is the most common cause of CAD, which diminishes the myocardial blood supply until the blood flow to the heart is limited causing the

    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

  • Coronary Artery Disease Research Paper

    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 (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

    841 Words  | 4 Pages

    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.

    blood vessels: arteries, capillaries, and veins, and they all differ in their histological features. Arteries are the thickest blood vessels of the three. They have a tunica intima which has an internal elastic lamina and endothelium (simple squamous epithelium), a tunica media, an external elastic lamina, and a tunica externa or adventitia. Because arteries are built to withstand pressure and stretching, they could be elastic or muscular arteries. It depends on the type of artery which tells us

By expanding the arteries they help reduce the symptoms of chest pains and help treat

  • Essay On Coronary Heart Disease

    540 Words  | 3 Pages

    Coronary heart disease is when plaque builds up inside the coronary arteries. The heart is a muscular pump located in the mediastinum that keeps blood flowing through the vessels. Coronary heart disease can develop because of hereditary or old age. Another way it develops is because of obesity, smoking, lack of exercise, anxiety, stress, and aggression. The pulmonary and systemic circuits carry blood to the organs in the body. The pulmonary circuit is on the right half of the heart. The pulmonary
