Intraperitoneal structures definition
Inside the peritoneum
Retro peritoneal structures
Posterior to the peritoneum eg; kidneys
3 main arteries that supplies the gastrointestinal system, liver, pancreas, gallbladder
- Celiac trunk
- Sup. Mesenteric
- Inf. Mesenteric
Main veins of the gastrointestinal system
