It is composed of a single layer of mesothelium supported by a thin layer of connective tissue termed the serous membrane parietal peritoneum The peritoneum lining the wall of abdominal and pelvic cavities is parietal peritoneum 。 visceral peritoneum covering the viscera peritoneal cavity The potential space between the parietal and visceral peritonea is the peritoneal cavity nullRelationship between the abdominopelvic viscera and peritoneum Intraperitoneal organs almost completely surrounds with peritoneum the stomach, superior part of duodenum, jejunum, cecum, vermiform appendix, transverse colon, sigmoid colon, spleen, ovary, uterine tube Interperitoneal organs covered by peritoneum on their three aspects the liver, gallbladder, urinary bladder, uterus, upper part of the rectum, ascending and descending colon. Retroperitoneal organs Only the anterior part of these organs is covered by the peritoneum the kidneys, suprarenal glands, ureters, major part of duodenum, pancreas (except for its tail), and lower part of the rectum nullStructures formed by the peritoneum Omenta The omentum is double-layered extension or fold of peritoneum that connects the greater curvature or lesser curvature of the stomach Lesser omentum hepatogastric ligament hepatoduodenal ligament right anterior :the bile duct left anterior : the proper hepatic artery posterior:hepatic portal vein nullGreater omentum gastrocolic ligament ⑴ nullomental bursa （lesser peritoneal cavity ） There is a potential, narrow space between the lesser omentum, the posterior wall of the stomach and the posterior wall of the abdomen Omental bursa and omental foramen anterior wall the lesser omentum, the posterior wall of the stomach and the gastrocolic ligament posterior wall the peritoneum covering the pancreas, the left kidney and suprarenal gland superior wall the inferior surface of the caudate lobe of the liver and the peritoneum covering diaphragm inferior wall the transverse mesocolon and the site that the anterior and posterior layers of the greater omentum fuse the left the spleen, the gastrosplenic and splenorenal ligament . the right the omental bursa communicates with the greater sac through the omental foramen.nullomental foramen (foramen of Winslow) is located posterior to the hepatoduodenal ligament (free edge of lesser omentum), upper bound The caudate lobe of the liver lower bound The superior part of the duodenum prozone the hepatoduodenal ligament Post bound The inferior vena cava Mesenteries Mesenteries mesentery mesoappendix transverse mesocolon sigmoid mesocolon nullfalciform ligament ligamentun teres hepatis coronary ligament right and left triangular ligaments Ligaments of the liver Ligaments nullLigaments of the spleen gastrosplenic ligament splenorenal ligament phrenicosplenic ligament nullHepatogastric ligament gastrosplenic ligament gastrocolic ligament gastrophrenic ligamentLigaments of the stomachphrenicocolic ligament nullFolds and peritoneal recesses of posterior abdominal wall the superior duodenal fold superior and inferior duodenal recesses retrocecal recesses intersigmoid recess Folds, peritoneal recesses, and pouches null rectus abdominisurinary bladderFolds and peritoneal fossae of anterior abdominal wall median umbilical fold ⑴ medial umbilical folds ⑵ lateral umbilical folds ⑶ supravesical fossa⑷ medial inguinal fossa (superficial inguinal ring ) ⑸ lateral inguinal fossa (deep inguinal ring ） ⑹⑴ ⑵⑶⑷ ⑸⑹parietal peritoneumnullFemale: the rectouterine pouch (Douglas pouch) ⑵ the vesicouterine pouch ⑶ Male ：rectovesical pouch ⑴Pouches ⑴⑵⑶nullleft suprahepatic spacesThe peritoneal cavity is divided into the supracolic and infracolic compartments by the transverse colon and transverse mesocolon Subdivision of the peritoneal cavity subphrenic space Suprahepatic space left anterior suprahepatic spaces left posterior suprahepatic spaces right suprahepatic spaces right anterior suprahepatic spaces right posterior suprahepatic spaces Subhepatic spaceSubhepatic spaceleft subhepatic spaces left anterior and left posterior subhepatic spaces right subhepatic spacesnullParacolic sulci Mesenteric sinusesleft paracolic sulcus right paracolic sulcusright mesenteric sinus left mesenteric sinusInfracolic compartment
