·The peritoneum is a two-layered continuous, transparent serous membrane lining the abdominopelvic wall,and covers the organs. 。Parietal peritoneum Sensitive,supplied by the same overlying somatic N, Pain from it is well localized ·Visceral peritoneum Insensitive,supplied by visceral N, Pain is poorly localized Innervate by: Foregut---at about epigastric region Midgut---umbilical Hindgut--- hypogastric(pubic cavity

1.the stomach and upper half of the duodenum(major papilla of duodenum)are derived from the foregut and supplied by the celiac trunk. 2.The distal half of the duodenum,the jejunum and ileum,cecum and appendix, ascending colon,and two thirds of the transverse colon are derived from the midgut and supplied by the superior mesenteric artery. 3.The distal third of the transverse colon,the descending colon,sigmoid colon, rectum,and the upper part of the anal canal are derived from the hindgut and supplied by the inferior mesenteric artery. the developmental and vascular junctions are at (1)the middle of the duodenum,where the bile duct ends, (2)the left part of the transverse colon

Peritoneal cavity -greater sac extends from the diaphragm to the pelvic floor potential space between the parietal and visceral layer of peritoneum, With nothing but thin film of fluid Male,is a closed sac, Female,communicates with the exterior through the uterine tubes,the uterus,and the vagina
• Peritoneal cavity －greater sac • extends from the diaphragm to the pelvic floor potential space between the parietal and visceral layer of peritoneum, With nothing but thin film of fluid Male, is a closed sac, Female, communicates with the exterior through the uterine tubes, the uterus, and the vagina
Function Secretion serous fluid moistens the organs. Absorption(at center of the diaphragm) ● Support and protection abdominal organs Resist infection:leucocytes
