Solution

The correct option is B 1500 mL
Expiratory Capacity (EC): Total volume of air a person can expire after a normal inspiration. This includes tidal volume and expiratory reserve volume (TV+ERV).

Expiratory capacity = Tidal volume + Expiratory reserve volume
= 500 mL + 1000 mL = 1500 mL

Q. Tidal volume and expiratory reserve volume of an athlete is 500 mL and 1000 mL respectively. What will be his expiratory capacity if the residual volume is 1200 mL?

Q. If expiratory reserve volume is 1100 ml residual volume is 1200 ml and tidal volume is 500 ml, what shall be the functional residual capacity?

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)

Q. Explain the terms: Vital capacity of lungs in terms of IRV (Inspiratory Reserve Volume), ERV (Expiratory Reserve Volume), TV (Tidal Volume) and RV (Residual Volume)

Q. Arrange the following in order of increasing volume.

1

2

. Residual volume

3

. Expiratory reserve volume

4

. Vital capacity
