Question

Quizplus · Accepted Answer

The force that creates the intrapleural pressure is surface tension. This is because the visceral and parietal pleurae are separated by a thin layer of fluid, which creates surface tension that pulls the two pleurae together and creates a negative pressure within the pleural cavity. This negative pressure helps to keep the lungs inflated and promotes gas exchange.
