Question

which of the following statements concerning the lungs and the pleura is true? multiple choice the pleural fluid assists in gas exchange. the pleural membranes adhere, but cannot slide past each other. parietal pleura covers the surface of each lung. the space between the visceral and parietal pleurae is called the mediastinum. each lung is suspended in a separate pleural cavity.

Explanation:

The lungs are surrounded by pleural membranes. The pleural cavity is a closed - off space for each lung. Pleural fluid allows the pleural membranes to slide during breathing. The visceral pleura covers the lung surface and the parietal pleura lines the chest wall. The mediastinum is the central part of the thoracic cavity, not the space between pleurae. Gas exchange occurs in the alveoli, not due to pleural fluid.

Answer:

Each lung is suspended in a separate pleural cavity.
