Question

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

Explanation:

The pleural cavity contains a thin film of serous fluid. This fluid creates surface tension which holds the visceral (covers the lungs) and parietal (lines the thoracic cavity) pleural membranes together. Surfactant is related to reducing surface tension in the alveoli of the lungs. Dense and loose connective tissues are not the agents that hold these two pleural membranes together.

Answer:

Thin film of serous fluid
