Answer to Question 1

ANS: D
Minute ventilation (exhaled) is denoted by E, which is calculated as the product of frequency of breathing (fB) times the expired tidal volume:

Answer to Question 2

ANS: D
For each breath, the gas left in the conducting tubes does not participate in gas exchange and is, in effect, wasted. Similarly, regional differences in ventilation cause some gas that does reach the alveoli to be wasted. This occurs in alveoli that have little or no perfusion. Ventilation occurring without perfusion defines dead space.
