SPLANCHNOLOGY Chapter 10 The PeritoneumGeneral description General description The peritoneum lines the wall of abdominal and pelvic cavities, and covers the abdominal and pelvic viscera. 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
