Quizplus · Accepted Answer

Serous membranes line body cavities that do not open to the exterior and consist of a mesothelium supported by connective tissue. They are tightly attached to the body wall and organs they cover. The parietal and visceral portions of serous membranes do touch and help reduce friction by secreting tiny amounts of transudate onto their surfaces.
