The serous fluid of the pleurae creates surface tension, which helps to hold the lungs open against the chest wall. This allows for proper lung expansion and contraction during breathing. The serous fluid also helps to reduce friction between the two pleurae, allowing them to slide smoothly over each other during breathing movements. It does not cause the two pleurae to stick together, which would impede breathing.
