Question

Which of the following statements about the pleurae is NOT true?

A) The pleural lining reduces friction during ventilation.
B) The parietal and visceral pleura are continuous.
C) The pleurae create one continuous cavity for both lungs.
D) The visceral pleura covers the lung tissue and lines the fissures of the lung lobes.

Answer 1

The correct answer is C) The pleurae create one continuous cavity for both lungs.

Step-by-step explanation:

The correct answer is C) The pleurae create one continuous cavity for both lungs.

The pleurae consist of two layers: the parietal pleura and the visceral pleura. The parietal pleura lines the thoracic wall, mediastinum, and diaphragm, while the visceral pleura covers the lung tissue and lines the fissures of the lung lobes.

The pleural cavity is the space between the parietal and visceral layers of the pleura, and it contains a small amount of pleural fluid that reduces friction during ventilation. Since the pleurae create two separate cavities for each lung, statement C is not true.
