The fluid that prevents friction between the pleural membranes is:
A)serous fluid
B)mucus

Question

Quizplus · Accepted Answer

The pleural membranes surround the lungs and the space between them is filled with serous fluid, which helps to reduce friction as the lungs expand and contract during respiration. Mucus is a thick, sticky fluid produced in the respiratory tract to help trap dust and other particles. Plasma is the liquid component of blood and does not directly relate to the pleural membranes. Synovial fluid is a lubricating fluid found in joints.
