serous membrane

serous membrane (serosa) n. a smooth transparent membrane lining certain large cavities of the body, such as the abdomen (see peritoneum) and chest (see pleura). The parietal portion of the membrane lines the walls of the cavity, and the visceral portion covers the organs concerned. The two form a closed sac, the inner surface of which is moistened by a thin fluid derived from blood serum, allowing frictionless movement of organs within their cavities. Compare mucous membrane.
