The peritoneum is the serous membrane which lines the abdominal cavity. It is a type of loose connective tissue covered by mesothelium. Extensions of the peritoneum form the mesenteries that support the abdominal contents. It functions to lubricate abdominal viscera , enhance the immune response and wall off infection in the abdomen to prevent peritonitis. | The peritoneum is the serous membrane which lines the abdominal cavity.
