Vital capacity is a measure of________________?
Correct answer: C. Tidal volume plus inspiratory reserve volume plus expiratory reserve volume
- A. Tidal volume
- B. Inspiratory reserve volume plus expiratory volume
- C. Tidal volume plus inspiratory reserve volume plus expiratory reserve volume
- D. Expiratory reserve volume plus reserve volume
Explanation
Vital capacity is the maximum volume expired after a maximal inspiration, so it equals tidal volume plus inspiratory reserve volume plus expiratory reserve volume. Residual volume is not included because it cannot be voluntarily exhaled.
