Question

Quizplus · Accepted Answer

Intrapulmonary pressure is the pressure within the air sacs of the lung, also known as alveoli. It can vary during the respiratory cycle and can either be greater than or less than atmospheric pressure. It is not the same as intrapleural pressure, which is the pressure within the pleural cavity between the lungs and chest wall. Intrapulmonary pressure is also not the same as the pressure within the bronchi, which can also vary during the respiratory cycle but is not the primary site of gas exchange.
