A person breathes in some volume of air by forced inspiration after having a forced expiration. This quantity of air taken in is
1. total lung capacity
2. tidal volume
3. vital capacity
4. inspiratory capacity
From the following relationships between respiratory volume and capacities, mark the correct option.
i. | Inspiratory Capacity (IC) = Tidal Volume + Residual Volume |
ii. | Vital Capacity (VC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV) + Expiratory Reserve Volume (ERV). |
iii. | Residual Volume (RV) = Vital Capacity (VC) — Inspiratory Reserve Volume (IRV) |
iv. | Tidal Volume (TV) = Inspiratory Capacity (IC) — Inspiratory Reserve Volume (IRV) |
