stomach, and spleen. The celiac trunk divides into three superior to the terminal aorta. It delivers blood to the ter-
branches: (a) The left gastric artery supplies the stomach minal portions of the colon (left colic and sigmoid arteries)
and the inferior portion of the esophagus. (b) The splenic and the rectum (rectal arteries).
artery supplies the spleen and arteries to the stomach
(left gastroepiploic artery) and pancreas (pancreatic arteries). The abdominal aorta also gives rise to five paired arteries
(c) The common hepatic artery supplies arteries to the (Figure 21–23):
liver (hepatic artery proper), stomach (right gastric artery), gall-
bladder (cystic artery), and duodenal area (gastroduodenal, 1. The inferior phrenic arteries supply the inferior surface
