Deoxygenated blood is received in the right atrium and pumped from the right ventricle through the pulmonary capillary bed, where carbon dioxide is exchanged for oxygen in the alveoli. Pulmonary venous return to the left atrium is circulated through the systemic capillary bed by the left ventricle (Figure 1-1).
