The pleura is associated with which organ system?

The pleura is a vital anatomical structure associated with the respiratory system. It consists of a double-layered membrane that surrounds the lungs, providing support and enabling smooth movements during respiration. The visceral pleura adheres directly to the lung surface, while the parietal pleura lines the thoracic cavity. This arrangement allows for the reduction of friction between the lung surface and the chest wall as the lungs expand and contract during inhalation and exhalation. Moreover, the pleura plays a role in generating pleural pressure, which is essential for proper lung function.

Regarding the other organ systems: the digestive system involves organs such as the stomach and intestines, which do not interact directly with the pleura. The nervous system includes the brain and spinal cord, neither of which is connected to the pleural membranes. The endocrine system comprises glands that produce hormones for various bodily functions, unrelated to the pleura. Therefore, the respiratory system is distinctively linked to the pleura.
