The volume of air remaining in the lungs after a tidal expiration is called the

A) expiratory reserve volume (ERV) .
B) residual volume (RV) .
C) vital capacity (VC) .
D) anatomic dead space.
E) functional residual capacity (FRC) .

Functional Residual Capacity (FRC)

The volume of air present in the lungs at the end of passive expiration, an important measure in pulmonary physiology.

Expiratory Reserve Volume (ERV)

The additional amount of air that can be exhaled from the lungs after a normal exhalation.

Vital Capacity (VC)

The greatest volume of air that can be expelled from the lungs after taking the deepest possible breath; an important measurement in respiratory health.
