Q.
Given that tidal volume is 600 mL, inspiratory reserve volume is 2500 mL and expiratory reserve volume is 800 mL, what is the value of vital capacity of lung?

Solution:
Vital capacity = Inspiratory reserve volume + Tidal volume + Expiratory reserve volume $= 2500 mL + 800 mL + 600 mL = 3900 mL$ Vital capacity is the volume of air breathed out after the deepest inhalation
