A) hyperventilation
B) exhalation
C) pause in breathing
D) apnea

Accepted Answer

Intrapulmonic pressure is the pressure within the pulmonary airways and alveoli. When intrapulmonic pressure is higher than atmospheric pressure (760 mm Hg at sea level), air flows out of the lungs, leading to exhalation.
