Quizplus · Accepted Answer

Expiratory reserve volume (ERV) refers to the amount of air that can be voluntarily expelled after completing a normal, quiet respiratory cycle. Total lung capacity (TLC) is the maximum amount of air that the lungs can hold, including residual volume (RV), which is the amount of air remaining in the lungs after maximum expiration. Tidal volume (TV) is the amount of air inhaled and exhaled during a normal breath. Inspiratory reserve volume (IRV) is the additional amount of air that can be inhaled after a normal inhalation.
