Vital capacity (VC) |
Total lung capacity (TLC) |
| 1. | It is the volume of air that a person can maximally exert themselves to breathe in and out of. | It is the total volume of air in the respiratory system and lungs following a maximal inspiration. |
| 2. | Tidal volume plus inspiratory reserve volume (VC = TV + IRV + ERV) is its total. A typical adult has between 4 and 4.6 litres. | TLC is equal to the sum of the residual volume and the vital capacity (TLC = VC + RV). It is 5100 - 5800 ml. |

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)
