This is different from organs that are not retroperitoneal, which have peritoneum on their posterior side and are suspended by mesentery in the abdominal cavity. The retroperitoneum can be further subdivided into the following: [2] Perirenal (or perinephric) space; Anterior pararenal (or paranephric) space; Posterior pararenal (or paranephric ...
The retroperitoneum or retroperitnium is an anatomical region that includes the peritoneum-covered organs and tissues that make up the posterior wall of the abdominal cavity and the pelvic space - which extends behind to the abdominal cavity. Definitions vary and can also can include the region of the wall of the pelvic basin.
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 ...
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.

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.
In humans, the kidneys are located high in the abdominal cavity, one on each side of the spine, and lie in a retroperitoneal position at a slightly oblique angle. [9] The asymmetry within the abdominal cavity, caused by the position of the liver , typically results in the right kidney being slightly lower and smaller than the left, and being ...
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.
