Q.
What happens when the intrapulmonary pressure is less than atmospheric pressure?

Solution:
Intrapleural pressure is the pressure of the air within the pleural cavity, between the visceral and parietal pleurae.
Air flows into the lungs largely due to a difference in pressure; atmospheric pressure is greater than intra-alveolar pressure, and intra-alveolar pressure is greater than intrapleural pressure. Air flows out of the lungs during expiration based on the same principle; pressure within the lungs becomes greater than the atmospheric pressure.
