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?

  • 1700 mL

  • 2200 mL

  • 2700 mL

  • 1500 mL


D.

1500 mL

Tidal volume = 500 mL

Expiratory Reserve Volume = 1000 mL

Expiratory Capacity = TV + ERV

                            = 500 + 1000

                            = 1500 mL
