15 Figure 2.1 The heart. (From E. N. Marieb, Human Anatomy and Physiology, 3 rd ed. New York: The Benjamin/Cummings Publishing Company, Inc., 1995.) The heart, illustrated in Figure 2.1, is divided into two functional halves, each half containing two chambers: an atrium and a ventricle. The atrium of each side empties into the ventricle on that side. There is no direct flow between the two atria or the two ventricles in a healthy individual. Blood is pumped by the pulmonary circuit from the right ventricle through the lungs and then into the left atrium. The blood is then pumped by the systemic circuit, from the left ventricle, through all the tissues of the body except the lungs, and then to the right atrium.
16 Figure 2.2 The systemic and pulmonary circulations. (From E. N. Marieb, Human Anatomy and Physiology, 3 rd ed. New York: The Benjamin/Cummings Publishing Company, Inc., 1995.) In both circuits, the vessels carrying blood away from the heart are called arteries and those carrying blood from either the lung or all other parts of the body back to the heart are called veins. Figure 2.2 illustrates the heart with the systemic and pulmonary circulations.
