Detailed explanation-1: -It is the total amount of air exhaled after maximal inhalation. The value is about 4800mL and it varies according to age and body size. It is calculated by summing tidal volume, inspiratory reserve volume, and expiratory reserve volume.
Detailed explanation-2: -Correct Answer: vital capacity The volume change that occurs between maximal inspiration and maximal expiration is known as vital capacity. Stated differently, vital capacity is the maximum volume of gas that can be exhaled after a maximum inhalation.
Detailed explanation-3: -Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation. It is equal to the sum of inspiratory reserve volume (IRV), tidal volume (TV), and expiratory reserve volume (ERV). So, the correct option is ‘Vital capacity’.
