This de-oxygenated blood passes through the tricuspid valve into the right ventricle. This blood is then pumped under higher pressure from the right ventricle to the lungs via the pulmonary artery. Left-Hand Side of the Heart The left-hand side of the heart receives oxygenated blood from the lungs (via the pulmonary veins) into the left atrium. This oxygenated blood then passes through the bicuspid valve into the left ventricle. It is then pumped to the aorta under greater pressure (as explained

and a closed system of vessels called arteries‚ veins‚ and capillaries. As the name implies‚ blood contained in the circulatory system is pumped by the heart around a closed circuit of vessels as it passes again and again through the various "circulations" of the body. The Heart * The heart is enclosed by a sac known as the pericardium. There are three layers of tissues that form the heart wall. The outer layer of the heart wall is the epicardium‚ the middle layer is the myocardium‚ and the

This causes systemic body circulation. To compare the two‚ both each have three semi-lunar cusps‚ which curve outward and into the opening of the receiving blood vessel. What separates the semilunar valves from the atrioventricular (AV) valves is that the semilunar valves contain no presence of papillary muscles or chordae tendineae. This is because pressure within the heart falls in this area‚ thereby forcing the semilunar valves to close on their own. The hearts is a prime member of the circulatory
