Consider the following situations for an adult human being --
I) The maximum amount of air that can be breathed out after a maximum inspiration is around 4500 ml.
II) Tidal volume is 500 ml.
III) Inspiratory reserve volume is 2500 ml.
What would be the Expiratory reserve volume in that individual ?

Correct answer: A. 1500 ml

Vital capacity is the maximum amount of air that can be breathed out after a maximum inspiration.

VC = TV + IRV + ERV

Given

VC = 4500

ml,

TV = 500

ml, and

IRV = 2500

ml.

Substituting the values:

4500 = 500 + 2500 + ERV

ERV = 4500 - 3000 = 1500

ml.

Answer: 1500 ml
