The 2-layered membrane that lines the abdominal cavity and covers and supports the abdominal organs. The peritoneum produces a lubricating fluid that allows the abdominal organs to glide smoothly over each other, and protects the organs against infection. It also absorbs fluid and acts as a natural filtering system. The peritoneum may become inflamed as a complication of an abdominal disorder (see peritonitis).
