Question

Quizplus · Accepted Answer

Dead space volume refers to the air that enters the respiratory tract and remains within the conducting zone passageways, without reaching the alveoli for gas exchange.

Answer: E
 Residual volume is the volume of air that remains within the lungs after forced expiration, which cannot be voluntarily expelled from the respiratory tract.

Answer: F
 Tidal volume refers to the normal volume of air that is inspired or expired during quiet breathing at rest.

Note: The other options are not matching with the provided definitions. Inspiratory reserve volume refers to the additional volume of air that can be forcefully inspired after a normal inspiration, while expiratory reserve volume is the additional volume of air that can be forcefully expired after a normal expiration. Vital capacity is the total volume of air that can be forcefully expired following a maximal inspiration.
