SEROUS MEMBRANE
Serous membranes or serosa are covering membranes which line body cavities that do not open to the exterior. They are found around organs that move a lot, such as the heart and lungs. The outer layer is called the parietal layer and is always attached to the surrounding tissues. The inner layer is called the visceral layer and is firmly attached to the organ it covers.
It is a smooth membrane consisting of a thin layer of cells which excrete serous fluid. Serous membranes line and enclose several body cavities, known as serous cavities, where they secrete a lubricating fluid which reduces friction from muscle movement. Serosa is not to be confused with adventitia, a connective tissue layer which binds together structures rather than reducing friction between them.
