    Arrange the following in the order of increasing volume (1) Tidal volume (2) Residual volume (3) Expiratory reserve volume (4) Vital capacity

    A) 1 < 2 < 3 < 4

    B) 1 < 3 < 2 < 4

    C) 1 < 4 < 3 < 2

    D) 1 < 4 < 2 < 3

    Correct Answer: B

    Solution :

    Tidal volume is volume of air inspired or expired with each normal breath. It is about 500 mL in adult person. Expiratory reserve volume is the extra amount of air that can be expired forcibly after a normal expiration. It is about 1000 mL. Residual volume: It is the volume of air which remains still in the lung after the most for after expiration it is about 1000 to 1500 mL. Vital capacity: Amount of air which can be maximum inspired and also maximum expired. It varies from 3400 ml-4800 ml depending on physiology of person.
