Solution
A person breathes in some volume of air by forced inspiration after having a forced expiration. This quantity of air taken in is vital capacity.
Explanation:
The greatest volume of air a person can breathe in after a forced expiration or the maximum amount of air a person can breathe in after a forced inspiration is referred to as vital capacity.

From the following relationships between respiratory volume and capacities and mark the correct answer.
- Inspiratory capacity (IC) = Tidal Volume + Residual Volume
- Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV).
- Residual Volume (RV) = Vital Capacity (VC) – Inspiratory Reserve Volume (IRV)
- Tidal Volume (TV) = Inspiratory Capacity (IC) – Inspiratory Reserve Volume (IRV)
