If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery. The clot or clump can block the artery which can lead to heart attack. There are several risk factors associated with CAD and could possibly build up on each other and make CAD an even greater risk. First, Men have a greater risk of CAD than women, although women’s risk of getting CAD increase after they go through menopause. As you get older, your age increases the risk of narrowed and damaged arteries, which of course leads to CAD.
What is High Blood Pressure? Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body. It’s normal for blood pressure to go up and down throughout the day, but if it stays up, you have high blood pressure. Another name for high blood pressure is hypertension. When blood pressure is high, it starts to damage the blood vessels, heart, and kidneys.
P5 describe physical and psychological changes due to the ageing process. In this assessment I will show how a human body has physical and psychological changes due to ageing process. Physical changes Cardiovascular System Atherosclerosis occurs when fats lays down in the wall of blood vessels and develop a narrowing of the arteries in older people. It can affect older people with high blood pressure, giving them stroke and heart attack. When the fats lays in the blood vessels, it increases the size and cause a blockage in the artery which can make a person get low breathing and chest pain.
Coronary artery disease is the leading cause of death for both men and women in the U.S. When the coronary arteries become partially blocked or clogged the result becomes coronary artery disease. Therefore this blockage limits the flow of blood from the coronary arteries, which are the major arteries supplying oxygen-rich blood to the heart. When the heart is working harder and needs more oxygen the coronary arteries expand. Here are a few examples of when the arteries expand, when a person is climbing stairs, exercising, or having sex.
1) Coronary artery disease occurs when fatty deposits called plaque build up inside the coronary arteries. The coronary arteries wrap around the heart and supply it with blood and oxygen. When plaque builds up, it narrows the arteries and reduces the amount of blood that gets to your heart. This can lead to serious problems, including heart attack. 2) Coronary artery disease is usually caused by a build-up of fatty deposits on the walls of the coronary arteries.
Another short term side effect is increased heart rate. When your heart beat increases it usually indicates that it is requiring more oxygen and therefore the heart has to work extremely hard. Your cardiac muscles blood flow is reduced due to that. Increased heart rate is your body panic mechanism. This is also the reason many marijuana users tend to be paranoid.
What Causes CHD?CHD is commonly caused by atherosclerosis, a condition which occurs when materials such as fat form a plaque build-up on artery walls, causing the arteries to grow narrow, and blood and oxygen flow lessen. As this occurs, blood and oxygen flow to the heart can drastically slow or even stop. This can cause shortness of breath, stable angina (chest pain), and heart attacks, especially when strenuously active (e.g. playing sports). There are certain factors that can increase the risk of getting CHD, including: Men in their 40's have a higher risk of getting CHD than woman, however, once women reach menopause, the risk is even across both genders.
The cardiovascular systems causes accumulation of fatty material in the heart muscle and arteries, and can contribute to high blood pressure. The respiratory system causes the lungs to have lower capacity for inhaling and exhaling air as the muscles that help to expand and contract the chest weakens. The digestive system weakens due to dietary practices and the aging process causing common problems like constipation. The genitourinary system causes urinary incontinence due to the decrease in the blood flow through kidney, and decreased efficiency to remove wastes from the blood as they age. The central nervous systems slower down the reaction time in elderly, and affects the perception and memory of elderly.
Blood Pressure Blood pressure is the force created by the heart as it pushes blood into the arteries and the circulatory system. When the heart pumps, it causes blood to flow through the arteries and into the arterioles. As the blood goes through the arterioles, the arterioles either contract or expand altering both the amount of blood flow and the resistance to blood flow. If the arterioles remain in a contracted form, they create high blood pressure. The heart must then pump harder because the arterioles are exerting a greater resistance to blood flow.
The invading organism causes symptoms, in part, by provoking a large immune response in the lungs. The capillaries become leaky, and protein-rich fluid seeps into the alveoli. This results in a less functional area for oxygen-carbon dioxide exchange. The patient becomes relatively oxygen deprived, while at the same time retaining large amounts of carbon dioxide. During this process, mucus production is increased.
