( A ) 3000 mL to 3500 mL, 1100 mL to 1500 mL
( B ) 2500 mL to 3000 mL, 1000 mL to 1100 mL
( C ) 1500 mL to 3000 mL, 1100 mL to 2000 mL
( D ) 1100 mL to 2500 mL, 1500 mL to 3000 mL

1 Answer

(B) is the right answer.

Respiratory Volumes and Capacities : Inspiratory Reserve Volume (IRV): Additional volume of air, a person can inspire by a forcible inspiration. This averages 2500 mL to 3000 mL. Expiratory Reserve Volume (ERV): Additional volume of air, a person can expire by a forcible expiration. This averages 1000 mL to 1100 mL
