_____ fluid lubricates the lung and thoracic surfaces, reducing friction as the lungs expand and contract.

Question

Quizplus · Accepted Answer

The pleural fluid is a lubricating fluid that reduces friction between the lung and thoracic surfaces during breathing movements. This fluid is produced by the pleura - a thin membrane that covers the lungs and lines the thoracic cavity. The fluid helps prevent the lungs from sticking to the chest wall as they expand and contract during breathing, which makes it easier for the lungs to move smoothly and efficiently.
