The value of inspiratory reserve volume in a healthy human is
1500 mL to 1700 mL.
3500 mL to 4000 mL.
2500 mL to 3000 mL.
500 mL to 1000 mL.
Respiratory Volumes -
Inspiratory Reserve Volume (IRV): Additional volume of air, a person can inspire by a forcible inspiration. This averages 2500 mL to 3000 mL.
Hence, the correct option is c. 2500 mL to 3000 mL
