Answer:

Gaseous exchanges continue in the lungs uninterrupted because some air is always present inside the lung alveoli even during expiration. ... Contraction of inspiratory muscles causes inspiration while relaxation causes expiration

Answer:

This happens because of the reason that even after the air present in the lungs is completely exhaled out there is still some air left in the lungs.

Explanation:

This air remaining in the lungs is known as the residual volume of the lungs and this residual volume is responsible for the exchange of gases in the lungs even after forced exhalation.
