Question

A) confined to the thoracic cavity.
B) confined to the abdominopelvic cavity.
C) serous membranes.
D) mucous membranes.

Accepted Answer

The pleura, pericardium, and peritoneum are all examples of serous membranes, which line the cavities and organs of the body and secrete a lubricating fluid to reduce friction. The pleura lines the thoracic cavity and surrounds the lungs, the pericardium surrounds the heart, and the peritoneum lines the abdominal cavity and covers internal organs. They are not confined to a single cavity or system but can be found throughout the body, particularly in areas where organs are surrounded or suspended in fluid-filled spaces.
