Parietal peritoneum
•lines abdominal wall
Visceral peritoneum

Epiploic foramen “Winslow”
•communicates the greater and lesser sac
Greater omentum
•fat folds of peritoneum that drapes down from the greater curvature of the stomach
Lesser omentum
•attaches duodenum and lesser curvature of the stomach to the liver
Falciform ligament
•divides the liver into right and left lobes
The margins of the bare area of the liver are formed by the
•Coronary ligament
Where is morison’s pouch located
•right subhepatic space
Which organ is retroperitoneal
- spleen
- pancreas
- stomach
- gallbladder
•pancreas
Glisson’s capsule
•surrounds the liver to provide shape and stability
The liver is divided into how many segments
•8 segments
Nutrient rich blood from the GI system arrives via
•hepatic portal vein

Gallbladder
•purpose to drain the liver of bile and store it until it’s transported to the duodenum to aid in digestion
The common bile duct is formed by the union of the
•common hepatic and cystic
Pancreas Location

- neck
- body
- tail (always points to the spleen)
Pancreas endocrine function
