Question

Quizplus · Accepted Answer

Intrapleural pressure is always negative, meaning that it is lower than atmospheric pressure. This negative pressure helps to keep the lungs inflated and prevents them from collapsing. In contrast, intrapulmonic pressure can be positive or negative depending on whether a person is inhaling or exhaling. Neither interpulmonic pressure nor interpleural pressure are commonly used terms in respiratory physiology.
