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?

TV $=$$500 \mathrm{mL}$

ERV $=$$1000 \mathrm{mL}$

Expiratory Capacity $=$$\mathrm{TV} + \mathrm{ERV}$ $=$$500 + 1000$ $=$$1500 \mathrm{mL}$

Note: The data of residual volume is not necessary to calculate expiratory capacity; residual volume is not a part of expiratory capacity.
