airway
The upper airway tract or the passage above the larynx, which includes the nose,

alveolar minute volume
The volume of air moved through the lungs in 1 minute minus the dead space;
calculated by multiplying tidal volume (minus dead space) and respiratory rate.
alveolar ventilation
The volume of air that reaches the alveoli. It is determined by subtracting the amount of
dead space air from the tidal volume.
American Standard Safety System
A safety system for large oxygen cylinders, designed to prevent the accidental
attachment of a regulator to a cylinder containing the wrong type of gas.

carina
Point at which the trachea bifurcates (divides) into the left and right mainstem bronchi.
Chemoreceptors
Monitor the levels of O2, CO2, and the pH of the cerebrospinal fluid and then provide
feedback to the respiratory centers to modify the rate and depth of breathing based on
the body's needs at any given time.
