Tidal Volume and Expiratory Reserve Volume of an athlete is 500mL and 1000mL, respectively. What will be his Expiratory Capacity if the Residual Volume is 1200mL?

  1. A
    1500mL
  2. B
    1700mL
  3. C
    2200mL
  4. D
    2700mL

Solution & Step-by-step Explanation

Expiratory Capacity (EC) is the total volume of air a person can expire after a normal inspiration.
EC=TidalVolume(TV)+ExpiratoryReserveVolume(ERV)
EC=500mL+1000mL=1500mL.
Note: Residual volume is not used in this calculation.
