Step-by-step solution
Tidal Volume (TV) is the volume of air inspired or expired during a normal breath. It is about 500-550 mL.- a-iii Inspiratory Reserve Volume (IRV) is the extra amount of air that can be inspired directly after a normal inspiration. It is about 2500-3000 mL.- b-i Expiratory Reserve volume (ERV) is the extra amount of air that can be expired forcibly after a normal expiration. It is about 1000-1100 mL.- c-iv Residual Volume (RV) is the volume of air which remains still in the lung after the most forceful expiration.
