The Human Heart Abstract: Dorlands Illustrated Medical Dictionary defines the heart as the viscus of cardiac muscle that maintains the circulation of the rootage. It is divided into cardinalsome cavities; two atria and two ventricles. The left atrium receives oxygenated blood from the lungs. From there the blood passes to the left ventricle, which forces it via the aorta, through the arteries to supply the tissues of the body. The right atrium receives the blood later it has passed through the tissues and has given up much of its oxygen. The blood thusly passes through the right ventricle into the lungs where it gets oxygenated.
There are four major valves in the heart; the left atrioventricular valve (also cognise as the mitral or bicuspid valve), the right atrioventricular valve (tricuspid), aortic valve, and the pulmonary valve. The heart tissue itself is nourished by the blood in the coronary arteries.2 Position of the Heart Within the ashes: The heart is placed obliquely...If you want to get a enough essay, order it on our website:
