Which of the Following Best Describes the Visceral and Parietal

Question

Which of the following best describes the visceral and parietal pleura?
A) Line the inner wall of the trachea and bronchi
B) Line the mediastinum
C) Are serous membranes that line the pleural cavity
D) Are surfactant-secreting membranes

Accepted Answer

The visceral and parietal pleura are serous membranes that line the pleural cavity. They are not involved in lining the trachea and bronchi (option A) or the mediastinum (option B). They also do not secrete surfactant (option D), which is produced by specialized cells in the lungs called type II alveolar cells.
