The peritoneal cavity is widely used in intraperitoneal injections to administer chemotherapy drugs, [5] [6] and is also utilized in peritoneal dialysis. [7] An increase in capillary pressure in the abdominal organs can cause fluid to leave the interstitial space and enter the peritoneal cavity, resulting in a condition called ascites.
The inner layer, the visceral peritoneum, is wrapped around the visceral organs, located inside the intraperitoneal space for protection. It is thinner than the parietal peritoneum. The mesentery is a double layer of visceral peritoneum that attaches to the gastrointestinal tract. There are often blood vessels, nerves, and other structures ...
In anatomy, the abdominal wall represents the boundaries of the abdominal cavity.The abdominal wall is split into the anterolateral and posterior walls. [1]There is a common set of layers covering and forming all the walls: the deepest being the visceral peritoneum, which covers many of the abdominal organs (most of the large and small intestines, for example), and the parietal peritoneum ...
Peritoneal recesses (or peritoneal gutters) are the spaces formed by peritoneum draping over viscera. [1] The term refers mainly to four spaces in the abdominal cavity; the two paracolic gutters and the two paramesenteric gutters. There are other smaller recesses including those around the duodenojejunal flexure, cecum, and the sigmoid colon.
The viscera are also covered by visceral peritoneum. Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. [1] It contains a serous fluid called peritoneal fluid that allows motion. This motion is apparent of the gastrointestinal tract. The peritoneum, by virtue of its connection to the two (parietal ...
Serous membranes have two layers. The parietal layers of the membranes line the walls of the body cavity (pariet- refers to a cavity wall). The visceral layer of the membrane covers the organs (the viscera). Between the parietal and visceral layers is a very thin, fluid-filled serous space, or cavity. [4]
In human anatomy, the mesentery is an organ that attaches the intestines to the posterior abdominal wall, consisting of a double fold of the peritoneum.It helps (among other functions) in storing fat and allowing blood vessels, lymphatics, and nerves to supply the intestines.
The mesothelium is a membrane composed of simple squamous epithelial cells of mesodermal origin, [2] which forms the lining of several body cavities: the pleura (pleural cavity around the lungs), peritoneum (abdominopelvic cavity including the mesentery, omenta, falciform ligament and the perimetrium) and pericardium (around the heart).
