Cardiovascular system It consists of the heart and blood vessels (arteries and veins). The heart It is a muscle that functions as an extremely powerful pump to drive blood through the arteries and suck the blood from the veins come. The size of the fist, weighs about 300 grams and pump 5 liters of blood per minute. The heart represents only 0.4% of total body weight but consumes 10% of the oxygen provided by breathing. Arteries These are the vessels that carry blood from the heart to all organs.

1) What are the main functions of this system? The main functions of the circulatory system are to move blood and lymph throughout the whole body, which transports nutrients and oxygen to cells of the body and removes waste products like carbon dioxide, and to keep temperature and pH levels regulated. 2) What organs are part of this system? The organs that are part of the circulatory system are the heart, the blood vessels, the arteries, the veins and the lungs, which aren't actually part of the

Studies conducted on obese children found that the left ventricle size and mass along with left atrial measurements were considerably larger than those with a normal BMI. Left ventricular mass is found by accounting for body size, including both height and weight (Sorof and Daniels, 2002). Left ventricle mass is linked with more epicardial fat in obese children. Epicardial fat is adipose tissue found around the walls of the heart and the membrane surrounding the heart which is a risk factor for CVD

HEART RHYTHMS * 0.4 sec is the PR wave (it is actually the P-Q wave but called the PR wave) and it should be ≤ 0.20 sec. If it’s ≥ than that it indicates 1° heart block. * NSR: normal sinus rhythm, contraction originates from SA node and beats at 60-100 bpm * Sinus (atrial) Bradycardia: SA node discharges at < 60 bpm. TREATMENT is atropine and pacemaker if they become symptomatic. Usually the contractions are irregular but the same distance apart so they are irregular-regular

According to Aronow (2012), “peripheral arterial disease may cause intermittent claudication which is pain or weakness with walking that is relieved with rest” (p. 375). PAD is a chronic arterial occlusive disease of the lower extremities caused by atherosclerosis. Just distal to the arterial obstruction is usually where the muscle pain or weakness may occur after exercise. PAD is a type of peripheral vascular disease, which also includes carotid artery disease, renal artery disease, aortic disease, and

heart disease is a condition in which plaque builds up inside the coronary arteries, also know as atherosclerosis (Fig 1). Doctors usually explain atherosclerosis as “hardening of the arteries,” but it is actually much more complex. Thanks to the ancient Greeks, the name itself conveys some of that complexity: athere is Greek for “porridge,” while sclerosis means “hardening.” In fact, atherosclerosis begins with deposits of soft, fatty material; only later does this mush build up in plaques that narrow

In order to understand hypercholesterolemia and hyperlipidemia an understanding of what cholesterol and lipids mean and do for an organism. Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins, hormones and most of the non-protein membrane of cells. Lipids are insoluble and nonpolar there for are not soluble in water. Fatty acids are long chain carboxylic acids (typically
