Quizplus · Accepted Answer

The amount of gas that can be inhaled over and above that which is normally inhaled during quiet breathing is known as the inspiratory reserve volume (IRV). Functional residual capacity (FRC) is the volume of gas remaining in the lungs after a normal tidal volume expiration. Expiratory reserve volume (ERV) is the amount of gas that can be exhaled over and above that which is normally exhaled during quiet breathing. Vital capacity (VC) is the total volume of air that can be exhaled after maximal inspiration.
