1. Peritoneum

   The peritoneum is the serous membrane forming the lining of the abdominal cavity or coelom in amniotes and some invertebrates, such as annelids. 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. The abdominal cavity (the space bounded by the vertebrae, abdominal muscles, diaphragm, and pelvic floor) is different from the intraperitoneal space (located within the abdominal cavity but wrapped in peritoneum). The structures within the intraperitoneal space are called "intraperitoneal" (e.g., the stomach and intestines), the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal" (e.g., the kidneys), and those structures below the intraperitoneal space are called "subperitoneal" or "infraperitoneal" (e.g., the bladder).

1. peritoneum

   The peritoneum is a large, thin, transparent serous membrane that lines the abdominal cavity and covers, in whole or in part, the viscera within the abdomen. It forms the boundary between the abdominal organs and the abdominal wall, and it supports the organs in the abdomen while also allowing nerves, blood vessels, and lymphatics to pass through to the organs. It can be divided into the parietal peritoneum which lines the abdominal wall, and the visceral peritoneum which covers the organs.

1. Peritoneum

   The peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom—it covers most of the intra-abdominal organs—in amniotes and some invertebrates. It is composed of a layer of mesothelium supported by a thin layer of connective tissue. The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves. The abdominal cavity should not be confused with the intraperitoneal space. The structures within the intraperitoneal space are called "intraperitoneal", the structures in the abdominal cavity that are located behind the intraperitoneal space are called "retroperitoneal", and those structures below the intraperitoneal space are called "subperitoneal" or "infraperitoneal".

1. Peritoneum

   A membrane of squamous EPITHELIAL CELLS, the mesothelial cells, covered by apical MICROVILLI that allow rapid absorption of fluid and particles in the PERITONEAL CAVITY. The peritoneum is divided into parietal and visceral components. The parietal peritoneum covers the inside of the ABDOMINAL WALL. The visceral peritoneum covers the intraperitoneal organs. The double-layered peritoneum forms the MESENTERY that suspends these organs from the abdominal wall.
