WBJEEWBJEE 2012Breathing and Exchange of Gases

Solution:

The maximum amount of air which can be breathed out through forceful expiration after a forceful inspiration is called Vital Capacity (VC). It is sum total of Tidal Volume (TV), Inspiratory Reserve Volume (IRV) and Expiratory Reserve Volume (ERV). The value for vital capacity is about 3.4 - 4.8 litres.
