Correct Answer

Explanation

The amount of air inspired or expired during normal breathing is known as tidal volume. For humans, the value of tidal volume is approximately 500 ml. However, out of this 500 ml, around 150 ml is considered dead space volume, which remains in the respiratory tract and does not participate in gaseous exchange. Tidal volume is an important parameter in assessing lung function, and abnormalities in tidal volume can indicate certain respiratory conditions.
