Intrapleural pressure is
Negative during expiration.
Intrapleural pressure is the air pressure in the pleural cavity
and also exists between visceral and parietal pleurae. This pressure
majorly depends on ventilation phase, the volume of the intrapleural cavity and
atmospheric pressure. During expiration, the Intrapleural pressure in the pleural cavity becomes
less negative which is commonly known as negative pressure.
