Question:

State the volume of air remaining in the lungs after a normal breathing.

Answer:

Residual Volume: The volume of air remaining in the lungs after a normal breath is called the residual volume. This air remains in the lungs to prevent lung collapse and maintain a constant oxygen supply to the bloodstream. The residual volume cannot be exhaled voluntarily and serves as a functional reserve of air within the respiratory system.
