Respiratory Volumes

Question

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?

RankGuru · Accepted Answer

1. **Definition of EC**: Expiratory Capacity (EC) is the total volume of air a person can expire after a normal inspiration.
2. **Formula**: $EC = TV + ERV$.
3. **Substitute Values**: 
   - Tidal Volume ($TV$) = 500 mL
   - Expiratory Reserve Volume ($ERV$) = 1000 mL
4. **Calculation**: $EC = 500 + 1000 = 1500	ext{ mL}$.
5. **Note**: Residual Volume ($RV$) is not needed for calculating Expiratory Capacity.
