What is the significance of vital capacity?
State the volume of air remaining in the lungs after a normal breathing.
Distinguish between IRV and ERV.
Distinguish between inspiratory capacity and expiratory capacity.
Distinguish between Vital capacity and Total lung capacity.
The vital capacity of the lungs is ______.
A person breathes in some volume of air by forced inspiration after having a forced expiration. This quantity of air taken in is ______.
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)
