Answer:
Explanation:
the maximum amount of air which can be breathed out through forceful expiration after a forceful inspiration is equal to the sum of Tidal Volume (TV), Inspiratory Reserve Volume (IRV) and Expiratory Reserve Volume (ERV) and is known as the vital capacity. This is the maximum capacity to ventilate the lungs. So, the correct option is 'True'.
