The amount of air expelled by inhaling deeply and exhaling as much as possible is the vital capacity, which is the maximum amount of air that can be moved in and out of the lungs during a single breath. Tidal volume is the amount of air moved in and out during normal breathing, inspiratory reserve volume is the maximum amount of air that can be inhaled beyond the normal tidal volume, expiratory reserve volume is the maximum amount of air that can be exhaled beyond the normal tidal volume, and minimal volume is the residual air that remains in the lungs after the most forceful expiration.
