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 ?

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

$V C = T V + I R V + ER V$

Given $V C = 4500$ ml, $T V = 500$ ml, and $I R V = 2500$ ml.

Substituting the values:

$4500 = 500 + 2500 + ER V$

$ER V = 4500 - 3000 = 1500$ ml.

Answer: 1500 ml
