Serous membranes are found lining which spaces?

Explanation:
Serous membranes line internal, closed body cavities and the surfaces of the organs within those spaces. They form a pair of layers (parietal lining the cavity and visceral covering the organ) with a small amount of serous fluid between to reduce friction as organs move. This is why they are found in spaces like the pleural cavities around the lungs, the pericardial space around the heart, and the peritoneal cavity in the abdomen. These cavities are inside the body and not open to the outside, unlike joint spaces (lined by synovial membranes), skin surfaces (cutaneous membranes), or the mucous-lined digestive tract.
