Which Volume of Air is Not Included in the Vital

Question

Which volume of air is not included in the vital capacity?
A) tidal volume
B) residual volume
C) inspiratory reserve volume
D) expiratory reserve volume

Accepted Answer

Residual volume is the volume of air that remains in the lungs even after a forced maximal expiration. This volume is not included in the vital capacity, which is the maximum volume of air that can be exhaled after a maximal inhalation. Tidal volume, inspiratory reserve volume, and expiratory reserve volume are all included in the calculation of vital capacity.
