Answer to Question 1

ANS: B
The pulmonary circulation arises from the right heart (Figure 9-30) and carries the entire cardiac output through the lung each minute. O2-reduced systemic venous blood returns to the right heart via the inferior and superior venae cavae. This blood is pumped to the lungs by the right ventricle through the pulmonic semilunar valve and on to the trunk of the pulmonary artery.

Answer to Question 2

ANS: D
The pulmonary venous system drains the capillary beds that have received O2 from the alveoli and delivers the oxygenated blood into the left atrium.
