Exploration of liver, gall bladder, pancreas, duodenum and spleen

Celiac plexus; posterior pancreaticoduodenal arteries

The liver and the portal vein have been removed. The source of the posterior pancreaticoduodenal artery from the superior mesenteric artery can be seen. Also the origin of the inferior pancreatic artery (6) from the middle colic is visible. The contiguoous celiac and superior mesenteric plexuses surround the aortic origins of the celiac and superior mesenteric arteries and obscure them from view.
