c)2.5-3.9l


please don't answer if u don't know.
and please explain this to​

Answer 1

Answer:

a)4.5-5.5 l

Explanation:

Vital capacity is the maximum volume of air a person can breathe in after a forced expiration. This includes ERV, TV and IRV or the maximum volume of air a person can breathe out after a forced expiration. Vital capacity can be calculated by subtracting Reserve volume from Total Lung Capacity.

VC =IRV+TV+ERV = 4 to 5 L

Hence, the correct answer is '4 - 5L'

Answer 2

Answer:

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, tidal volume, and expiratory reserve volume. It is approximately equal to Forced Vital Capacity (FVC).
