The vital capacity is the maximum amount of air that can be expelled from lungs by forced exhalation after a forced inhalation. It is equal to the sum of tidal volume (TV), inspiratory reserve volume (IRV) and expiratory reserve volume (ERV).

V C = T V + I R V + ER V

= 500 + 3000 + 1100

= 4600 m l
