Answer to Question 1

ANS: A

Answer to Question 2

ANS: C
The four lung capacities are TLC, inspiratory capacity (IC), FRC, and the VC. These volumes and capacities are shown in Figure 20-10. The lung volumes that can be measured directly with a spirometer or pneumotachometer include VT, IC, IRV, ERV, and VC.
