Solution

Inspiratory capacity (IC) is the total volume of air a person can inspire after a normal expiration. This includes tidal volume and inspiratory-reserve volume. Whereas expiratory capacity (EC) is the total volume of air a person expire after a normal inspiration. This includes tidal volume and expiratory reserve volume.

Q. Assertion :If two men, expire the same volume of air after normal inspiration, they have the same expiratory capacity. Reason: Expiratory capacity includes tidal volume and inspiratory reserve volume.

Q. 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)
