(Top) Graphic shows the stomach and proximal duodenum in situ. The liver and gallbladder have been retracted upward. Note that the
lesser curvature and anterior wall of the stomach touch the underside of the liver and the gallbladder abuts the duodenal bulb. The
greater curvature is attached to the transverse colon by the gastrocolic ligament, which continues inferiorly as the greater omentum,
covering most of the colon and small bowel. (Bottom) Graphic shows the lesser omentum extending from the stomach to the porta
hepatis, divided into the broader and thinner hepatogastric ligament and the thicker hepatoduodenal ligament. The lesser omentum
carries the portal vein, hepatic artery, common bile duct, and lymph nodes. The free edge of the lesser omentum forms the ventral
margin of the epiploic foramen. Note the layers of gastric muscle; the middle circular layer is thickest.
