What organs are found in the peritoneum?
The peritoneum is comprised of 2 layers: the superficial parietal layer and the deep visceral layer. The peritoneal cavity contains the omentum, ligaments, and mesentery. Intraperitoneal organs include the stomach, spleen, liver, first and fourth parts of the duodenum, jejunum, ileum, transverse, and sigmoid colon.
What function do the peritoneal membranes provide for the organs inside of this Coelomic cavity?
It covers most of the intra-abdominal (or coelomic) organs, and is composed of a layer of mesothelium supported by a thin layer of connective tissue. This peritoneal lining of the cavity supports many of the abdominal organs and serves as a conduit for their blood vessels, lymphatic vessels, and nerves.
