The right side of the heart pumps blood to the lungs while the left side pumps blood to the rest of the body. Blood from the body enters the right atrium though the vena cava. It then flows into the right ventricle where it is pumped to the lungs through the pulmonary artery, which carries deoxygenated blood to the lungs. In the lungs, oxygen is loaded onto red blood cells and returns to the left atrium of the heart via the pulmonary veins. Blood then flows into the left vent ... ricle where it is pumped to the organs and tissues of the body. Oxygen is downloaded from red blood cells into the various organs while carbon dioxide, a waste product of metabolism, is added to be removed in the lungs. Blood then returns to the right atrium to start the cycle again. The pulmonary veins are unusual in that they carry oxygenated blood, while the pulmonary artery carries deoxygenated blood. This is a reversal of duties versus the roles of veins and arteries in the rest of the body. short length mother of the bride or groom collections
