An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries. Pulmonary arteries carry blood from the heart to the lungs where the blood picks up oxygen. The oxygen rich blood is then returned to the heart via the pulmonary veins. Systemic arteries deliver blood to the rest of the body. The aorta is the main systemic artery and the largest artery of the body. It originates from the heart and branches
up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. Atherosclerosis can lead to serious problems, including heart attack, stroke, or even death. When atherosclerosis affects the arteries of the heart it
Peripheral artery disease is usually caused by atherosclerosis, which is when fatty deposits accumulate in the arteries of, most likely, limbs. This does affect all arteries throughout the body, then in turn, slowing the blood flow. PAD may also be due to inflammation of the blood vessels, injury to the extremities, or even exposure to radiation. “Peripheral arterial disease (PAD) affects approximately 10% of the American population” (Gurbir Dhaliwal; Peripheral arterial disease: Epidemiology, natural
Coronary Artery Disease can be very deadly. It is actually listed as the number 1 killer in America. It is documented that Coronary Artery Disease has affected over 13 million Americans. Coronary Artery Disease can also be known as Heart Disease. CAD happens when plaque builds up in the arteries, resulting in blood flow being blocked. This can have deadly consequences such as strokes and heart attacks. This happens when the walls of the arteries change from being smooth and elastic, to hard and rigid
Coronary Artery disease is when plaque builds up in the arteries around the heart, which can cause a heart attack. Coronary Artery disease is also one of the leading causes of death of in the United States. Many different medical places are trying to come up with a resolution to this disease, however there are only temporary fixes. The United States is spending a major amount of money to try and find a solution. There are many different symptoms include chest pressure or pain, shortness of breath
Coronary artery disease (CAD) is one of the most common types of heart diseases. In the United States, CAD is the leading cause of death in both men and women. The disease occurs when a waxy substance called plaque builds up inside the coronary artery. The coronary arteries supply oxygen-rich blood to your heart muscles. Both of my grandfathers suffer from coronary artery disease and I want to learn more about the disease to better understand how it affects them both mentally and physically. Although
Coronary Artery Disease is a type of heart disease that is the leading cause of heart attacks. It is the most common type of heart disease in the United States. It is also the leading cause of death for both women and men. I have chosen to write about this disease because my grandfather has coronary artery disease. In 2011 he had a procedure done called coronary angioplasty and in the process had three stents placed inside his arteries. A little over a year later, he ended up having a triple bypass
veins or arteries in your extremities preventing blood from reaching them. (as shown in figure 1.3) Because blood cannot reach it, and therefore no oxygen either, the affected area will lose feeling and eventually die. This can affect almost anyone but primarily affects Asian and Middle Eastern men in there 40’s and 50’s, due to heavy Tabaco consumption, as well it can be transferred genetically. Symptoms for
1. The three differences between arteries and veins are which veins they have few layers of smooth muscles and connective tissue unlike arteries which have many layers of smooth muscle tissues. The difference in the two is also veins have very little elastic as well as a wide lumen and arteries have several layers elastic and a regular lumen. Last but not least veins carry oxygenated poor blood to the heart and arteries carry oxygenated blood away from the heart. 2. Blood pressure, flow and resistance

My father suffers with this disease and had a heart attack three years ago this is why I have decided to understand and learn more about Coronary Artery Disease. This disease has been in my family for three generations. The main reason why this occurred in my family was the unhealthy foods they were consuming along with stress. These were the factors that interrupted the distribution of blood to the
The Structure and Function Of Arteries, Veins and Capillaries In its route from the heart to the tissues, the blood passes through channels of six foremost types: elastic arteries, muscular arteries, arterioles, capillaries, venules and veins. I intend to explore the structure and function of arteries, veins and capillaries. When an artery branches into smaller and smaller vessels, eventually the blood vessel is too small to see with the naked eye. At that point, it is called an arteriole

Juliet Anosike Medical Terminology 178 ISCHEMIC HEART DISEASE Ischemic Heart Disease, also known as Coronary Artery Disease, is a condition that affects the supply of blood to the heart. Coronary artery disease may show no signs of symptoms, or chest pain before you know heart attack. The blood vessels are narrowed or blocked due to the deposition of cholesterol on their walls. This reduces the supply of oxygen and nutrients to the heart muscles, which is essential for proper functioning of the heart
Introduction Coronary artery disease (CAD) is caused by reduced blood flow in the coronary arteries. This subsequently leads to reduced oxygenation to the myocardium, resulting in transient ischemia or angina. CAD may cause permanent damage to myocardial cells or infarction. The left ventricle of the heart is most susceptible to CAD. The causes of CAD include atherosclerosis, congenital defects, coronary artery spasm, dissecting aneurysm, infectious vasculitis and syphilis. Atherosclerosis and vasospasm
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. Cholesterol containing deposits or plaque on your arteries are usually to blame for coronary artery disease. When plaques build up, they narrow your coronary arteries, causing your heart to receive less blood. Eventually, the decreased blood flow may cause chest pain, shortness of breath, or other coronary artery disease signs and
Introduction Coronary artery disease is a heart disease characterized by narrow arteries and restricted blood flow in arteries and is the major cause of morbidity and mortality globally.[1] According to WHO estimation, 6.8% in men and 5.3% in women are affected globally.[2-4] Cardiovascular disease account for 29% of all deaths in Canada; of all the cardiovascular death, 54% and 23% was due to ischemic heart disease and heart attack, respectively. The total costs for heart disease and stroke were
and hypogenetic lung syndrome (scimitar syndrome). In 1946, Pryce introduced the term ‘sequestration’ to describe congenital abnormalities characterised by an anomalous systemic arterial supply to the lung and atresia or hypoplasia of the pulmonary artery. Sequestration was defined by Pryce as a “disconnected (dislocated, ectopic) bronchopulmonary mass or cyst with an anomalous systemic blood supply”. Since Pryce’s early description of sequestration, a wide spectrum of bronchopulmonary- vascular malformations
vessels are called coronary arteries. They originate in the aorta and supply the heart muscle with oxygen rich blood. Coronary arteries consist of Right Coronary Artery, that branches into Marginal RCA and Posterior Descending Artery, and Left Main Coronary Artery, which branches into Left Circumflex, Marginal LCA and Left Anterior Descending Artery. In order for the heart to function properly the coronary arteries should be constantly supplying oxygen, if any of these arteries becomes blocked we experience
done and makes a determination of a heart attack. The cardiologist is immediately called who takes the patient to the catheterization lab. The cardiac catheterization and the coronary angiogram is completed and a diagnosis of multivessel coronary artery stenosis is made. Patient needs cardiac surgery in the next few hours to revascularise the heart. There is no cardiac surgery facility in the hospital and the patient needs to be transferred to the regional tertiary center which is about an hour away
Atherosclerosis is a cardiovascular disorder that causes a buildup of plaque in the arteries. The plaque is made of substances found in the blood, such as calcium, cholesterol, and fat, (“What is Atherosclerosis”). This buildup can eventually lead into other serious diseases. One disease that atherosclerosis leads to is coronary heart disease, which is the number one fatal disease for males and females in the United States, (“10 Important Facts”) . Atherosclerosis is a developmental disorder, meaning
