The amount of air taken in (inspiration) or breathed out (expiration) during normal breathing is called tidal air. Reserve air is the air that can be forced out of the lungs after normal expiration. The amount of air that the lungs can bring in during forced inspiration is called complemental air. Vital capacity is the volume of air exhaled during forced breathing and is the sum of tidal air, reserve air, and complemental air. The lungs are never completely empty of air.
