Question

11 what normally holds the visceral and parietal pleural membranes together? multiple choice surfactant loose connective tissue thin film of serous fluid dense connective tissue

Explanation:

The visceral and parietal pleural membranes are part of the pleural cavity. A thin film of serous fluid (pleural fluid) is present between them. This fluid reduces friction during breathing movements and also due to surface tension, it holds the two membranes together. Surfactant is related to reducing surface tension in the alveoli (not for holding pleural membranes). Loose and dense connective tissues are not the agents that hold these two pleural membranes together.

Answer:

Thin film of serous fluid.
