peritoneum
Peritoneal membrane refers to a layer of mucosa in the presence of higher vertebrate abdominal cavity, mainly composed of mesothelial cells, by the support of connective tissue formed by a layer of membranous tissue. Peritoneal cover most of the intra-abdominal organs, can secrete mucus moisturizing the surface of the organ to reduce friction between organs. The blood, lymph and nerve tissue of the abdominal organs are connected to the outside through the peritoneum. The peritoneum also has the effect of absorbing impact to protect the internal organs. Intraperitoneal refers to the spine, abdominal muscles, diaphragm and pelvic floor of the space, should be careful not to form the cavity surrounded by the peritoneum confused. For example, the kidney is located in the abdominal cavity but is not covered by the peritoneum, but after the peritoneum. Although it is a continuous cavity, but the structure of the peritoneum can be subdivided into three parts ▪ outer layer, called the peritoneum, covering the medial wall of the abdominal wall. ▪ The inner layer, called the visceral peritoneum, is covered on the surface of the abdominal cavity. ▪ The space between the two layers of the peritoneum and visceral peritoneum is called the peritoneal cavity and contains about 50 milliliters of serous fluid. It has a lubricating effect that reduces the friction between the peritoneal and visceral membranes. ...
