Distinguish between Vital capacity and Total lung capacity.

Explanation

Vital Capacity (VC) : It is the total volume of air that can be expelled from, the lungs during maximum exhalation.
`VC = TV + IRV + ERV`
`= 500 + 2500 + 1100`
`=4100 ml` approx.
Total lung capacity (TLC) : It is the maximum volume of air that can enter the lungs during forceful inspiration,
`TLC = VC + RV = 4100+ 1600 = 5200` approx.
