40. intrapulmonary pressure is the
a) pressure within the pleural cavity
b) pressure within the alveoli of the lungs
c) negative pressure in the intrapleural space
d) difference between atmospheric pressure and respiratory pressure

pressure within the alveoli of the lungs

Explanation:

Pulmonary ventilation involves three different pressures:

Atmospheric pressure

Intra Alveolar (intrapulmonary) pressure

Intrapleural pressure

Atmospheric pressure is the pressure of the air that is exerted outside the body. Intrapulmonary pressure is the pressure exerted inside the alveoli of the lungs. Intrapleural pressure is the pressure within the pleural body cavity.

this is math not biology xd
