The gastric blood supply from the celiac trunk is shown. The lesser curve is supplied by the right gastric artery from the hepatic, and the left gastric, usually a branch of the celiac trunk. The greater curve is supplied by the right and left gastroepiploic arteries from the gastroduodenal and splenic respectively, and by the short gastrics from the splenic.

The gastroduodenal artery branches from the common hepatic artery and passes between the duodenal bulb and head of the pancreas, where it is vulnerable to erosion by a deeply penetrating posterior ulcer.

A duodenal ulcer initially causes bleeding by eroding the submucosal vessels of the duodenal wall. The base of such an ulcer is characteristically white due to fibrinous exudate and the collagen of the wall.
