Question

Quizplus · Accepted Answer

150 mL of inspired air is stopped in the airway leading to the alveoli, which is known as dead air space. Vital capacity refers to the maximum amount of air that can be exhaled after a maximum inhalation. Bronchial air refers to the air in the bronchi and bronchioles, which is not the same as the 150 mL of dead space air. Tidal volume refers to the normal volume of air breathed in and out during a respiratory cycle, but it does not account for the 150 mL of dead space air.
