The kidneys are located behind the peritoneum, in the retroperitoneum, outside the abdominal cavity. 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 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 ...
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.
In human anatomy, the greater sac, also known as the general cavity (of the abdomen) or peritoneum of the peritoneal cavity proper, is the cavity in the abdomen that is inside the peritoneum but outside the lesser sac. A description of the greater sac in three dimensions.
Peritoneal fluid is a serous fluid made by the peritoneum in the abdominal cavity which lubricates the surface of tissue that lines the abdominal wall and pelvic cavity. It covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites. Sampling of peritoneal fluid is generally performed by paracentesis.
The lower portion is the pelvic cavity, and it contains the urinary bladder, the rest of the large intestine (the lower portion), and the internal reproductive organs. [2] [3] There is no membrane that separates out the abdominal cavity from the pelvic cavity, so the terms abdominal pelvis and peritoneal cavity are sometimes used.
There are two paracolic gutters: The right lateral paracolic gutter. The left medial paracolic gutter. The right and left paracolic gutters are peritoneal recesses on the posterior abdominal wall lying alongside the ascending and descending colon.
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 ...
