Ventilatory air flow occurs down pressure gradients. Upon inspiration, the respiratory muscles generate subatmospheric Ppl, which are transmitted to the alveoli. Air flows into the lungs down a pressure gradient from the atmosphere to the alveoli. During expiration, the respiratory muscles compress the intra-pleural space, creating positive pressure in the alveoli that force air out to the atmosphere. Airway resistance is the primary determinant of the pressure gradient necessary to produce a given flow rate.
