Description
The oral cavity, salivary glands, and pharynx are supplied by branches of the external carotid artery. In the thorax, the esophagus is supplied by branches of the thoracic aorta.
Structures of the foregut including the abdominal esophagus, stomach, and upper duodenum are supplied by branches of the celiac trunk.
Structures of the midgut, including the lower duodenum, jejunum, ileum, appendix, cecum, ascending colon, and proximal two thirds of the transverse colon are supplied the superior mesenteric artery.
Structures of the hindgut, including the distal third of the transverse colon, descending colon, sigmoid colon and upper third of the rectum are supplied by the inferior mesenteric artery. The rectum also receives arterial supply from the rectal branches of the iliac arterial tree which also supply the anal canal and anus.
The accessory organs of the digestive system in the abdominal cavity include the liver, gallbladder, and pancreas. They are supplied by the branches of the celiac trunk. The pancreas is also supplied by the inferior pancreaticoduodenal artery, a branch of the superior mesenteric artery.
