The human body cells need oxygen in order to function and the respiratory system allows this to happen. Consisting of air passages‚ pulmonary vessels‚ the lungs and breathing muscles‚ it supplies fresh oxygen to the blood which can be fed to other parts of the body. The ribs‚ rib muscles and diaphragm all play a part in allowing air into and out of the lungs‚ (oxygen going into the body and carbon dioxide leaving the body). This is known as ventilation. When we breathe in we inhale and when we

A.1 (1) Higher plants possess xylem which is associated with the transport of water. (2) Water absorbed by the root from the soil is transported to stem‚ branches‚ leaves and flowers. (3) The main structural components of the xylem responsible for the transport of water are tracheids and vessels. (4) As the root cells are directly in contact with soil‚they take up

Types of heart diseases include coronary artery disease‚ cardiomyopath‚ valvular heart disease‚ pericardial disease‚ and congenital heart disease. The most common type of heart disease is coronary artery disease. Coronary artery disease (CAD) is when the arteries that supplies blood for the heart muscle gradually hardens and thickens (artherosclorosis) because of the buildup

Health Problem Coronary heart disease is a chronic disease in which plaque‚ fatty deposits‚ builds up inside the coronary arteries which supply blood to the heart. The build up of plaque is called atherosclerosis and can develop for many years undetected. Some common symptoms of coronary heart disease are chest pain‚ shortness of breath‚ and extreme fatigue with exertion‚ in turn increasing the risk of other health issues such as angina pectoris and eventually heart attacks. Today‚ coronary heart disease

Coronary artery bypass graft surgery (CABG) is an advance surgical method meant for treating coronary heart diseases or CHD. In coronary artery bypass surgery‚ healthy veins or arteries from different parts of the body are grafted around the heart or onto the blocked aorta. These grafted portions bypass the blocked areas of the artery and thus create a new route for the blood to reach the heart. Coronary artery bypass graft surgery or CABG is one of the most popular open heart surgery methods performed

Introduction For the last decades‚ the number of fatalities from coronary heart disease (CHD) in Australia has steadily declined‚ however it remains one of the leading causes of all deaths and the number one cause of cardiovascular deaths among Australian population (Australian Institute of Health and Welfare [AIHW]‚ 2011). Coronary heart disease refers to the conditions that affect the blood vessels that supply the heart muscle with nutrients and oxygen (Craft‚ Gordon‚ & Tiziani‚ 2011). There

Hypertension (HTN) is a risk factor for coronary heart disease and account the single most important risk factors for stroke‚ affecting more than 1 billion people worldwide and is considered as one of the top global risk factor for mortality (Kearney et al 2005). The incidence of HTN rises with increasing age; indeed‚ the greater of elderly people have high blood pressure (BP) (Franklin 2006). Suggesting that an individual with normal BP older than 50 years of age‚ the probability during the next

Coronary Artery Disease 10/31/2005 This paper will serve as a case study for the condition known as coronary artery disease (CAD). CAD occurs when the coronary arteries become hardened and narrowed; this is due to the buildup of plaque on the inner lining of the arteries. Blood flow to the heart is reduced as plaque narrows the coronary arteries‚ thereby decreasing the oxygen supply to the heart muscle. This loss of oxygen in the blood can lead to ischemia and later‚ myocardial infarction

1. Procedure Coronary Artery Bypass Graft (CABG) is performed when a patient has disease of the coronary arteries. This is usually caused by atherosclerosis which is clogging of the arteries or hardening by cholesterol of plaque. Coronary Artery Bypass is done to improve the blood flow of the heart. The surgeon bypasses the obstructed artery using a healthy artery that is harvested from another part of the body and placed in the heart to reroute the blood flow around the blocked area. Usually the
