Pleural Cavity and Thoracic Cavity Quiz

The pleural cavity is bounded superiorly by the neck and inferiorly by the diaphragm.

The thoracic cavity is bounded anteriorly, laterally, and posteriorly by the chest wall, and inferiorly by the diaphragm.

The pleural cavity covers the lung surface, providing a low-friction environment that allows the lungs to move smoothly during breathing.

The pleural cavity is divided into two layers: the parietal pleura, which lines the thoracic cavity, and the visceral pleura, which covers the lung surface.

The pleural cavity is mainly drained by the lymphatic system.

Parietal pleura lines the inner surface of the thoracic cavity, while the visceral pleura directly covers the lung surface.

The pleural cavity extends from the root of the neck superiorly to the diaphragm inferiorly.

Approximately 100 ml of pleural fluid is produced per hour.
