The heart is a four-chambered pump about the size of the fist (Figure 7.6). The right atrium receives blood returning from the tissues of the body and pumps it to the right ventricle, from where it is pumped to the lungs via the pulmonary artery. Gaseous exchange takes place in the lungs. Hemoglobin in blood absorbs oxygen (a process known as oxygenation) and the oxygenated blood returns to the left atrium of the heart via the pulmonary vein. It passes to the left ventricle where it is pumped via the aorta through a series of ever branching blood vessels. Most tissues of the body are permeated by capillaries—tiny blood vessels with internal diameters not much larger than a red blood cell.

The heart has four chambers, on both atria and on the right ventricles. The heart is a beefy organ that constantly drives blood throughout the body. There are two different pumping systems and the blood cannot move easily between them. The function of the right atrium is to bring blood into the heart. In Figure 11.1, the top left shows the right atrium.

The systemic circulation provides the functional blood supply to all body tissue. It carries oxygen and nutrients to the cells and picks up carbon dioxide and waste products. Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the body’s tissues. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart. It then moves into the right ventricle, and the above cycle is repeated, equivalent to one iteration in our proposed algorithm.
