Alveolar ventilation refers to the volume of gas that reaches the alveoli (gas-exchange zone) of the lungs per unit time. Anatomical dead space refers to the volume of air in the conducting zone that does not participate in gas exchange. Minute ventilation is the total volume of air that enters or leaves the respiratory tract per minute. Tidal volume refers to the volume of air inspired or expired with each normal breath.
