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?

View answer and explanation

Correct option: A

1500 mL

Option A (1500 mL) is correct because Expiratory Capacity (EC) is the sum of Tidal Volume (TV) and Expiratory Reserve Volume (ERV), so EC = TV + ERV = 500 mL + 1000 mL = 1500 mL.
