Question

Quizplus · Accepted Answer

The typical value for intrapleural pressure is approximately -3 millimeters of mercury (mm Hg). This negative pressure helps to keep the lungs inflated and allows for normal breathing. Positive pressure (choices A and B) in the intrapleural space can lead to collapsed lungs, while a lack of negative pressure (choices C and E) can also lead to lung collapse.
