Which of the following best describes the location of the pleural cavity?

The pleural cavity is best described as the space surrounding the lungs. This cavity is specifically situated between the two layers of pleura—the visceral pleura that is attached to the surface of the lungs and the parietal pleura that lines the chest wall. The pleural cavity contains pleural fluid, which helps reduce friction during breathing and allows the lungs to expand and contract more easily.

Understanding this anatomical location is crucial for recognizing how it relates to respiratory functions and the protection of the lungs. In contrast to the other options, which refer to different body regions or organ systems, the pleural cavity's direct association with the lungs is what defines its location within the thoracic cavity.
