Peritoneum
Parietal peritoneum lines the abdominal wall; visceral peritoneum covers many organs. Mesenteries convey vessels, nerves and lymphatics to attached viscera.
Gut and accessory organs
Stomach, small and large bowel process food and move contents; liver, gallbladder and pancreas contribute bile, metabolic processing and digestive secretions.
Retroperitoneum
Kidneys, ureters, aorta and inferior vena cava occupy retroperitoneal positions; only parts of some GI organs are secondarily retroperitoneal.
Vascular patterns
Celiac trunk, superior mesenteric and inferior mesenteric arteries predominantly supply foregut, midgut and hindgut derivatives, with collateral variation.
