Question:

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

1500mL

2200mL

2700mL

1700mL

Solution:

Correct option is A. 1500mL
Tidal Volume=500ml
Expiratory Reserve Volume=1000ml
Expiratory Capacity=TV+ERV=500+1000=1500ml.
So, the correct answer is '1500 mL'.
