"pleural space"의 정의 및 의미

What is "pleural space"?

The pleural space is a vital anatomical region in the human body that exists between the visceral and parietal layers of the pleura. It is a thin, fluid-filled space that acts as a lubricating cushion between the lungs and the chest wall, allowing for smooth and frictionless movement during breathing. The pleural space helps to maintain the integrity of the lungs, preventing them from collapsing and promoting their expansion and contraction with each breath. It also facilitates the exchange of gases within the respiratory system, ensuring proper oxygenation of the blood. The pleural space is crucial for the optimal functioning of the respiratory system and for maintaining respiratory health.
