Explain why VC does not change with exercise

Solution

Vital capacity represents the greatest volume air that you can expel from your heart after taking the long deep possible breath. But lungs always will try to retain certain amount of oxygen inside that is known as residual volume. So to calculate your lung capacity one needs to consider both the vital capacity and residual volume.

The vital capacity of a person depends on its age, height, gender etc. And it has been estimated up to 4L for human lungs. That is the reason why VC does not change with exercise as it depends on the age, height and gender of that particular person.
