A detailed medical diagram shows the peritoneum as a thin, transparent membrane lining the inner abdominal wall and covering several major organs.
Noun: A large, thin, continuous sheet of serous membrane that lines the inner walls of the abdominal cavity and folds inward to cover and support the majority of the abdominal organs (viscera). It secretes a lubricating fluid that allows the organs to move smoothly against each other.
