Gastrointestinal Tract Blood Supply

Each region of the embryonic gastrointestinal tract has a specific arterial supply which historically defined the 3 adult gastrointestinal tract regions.

  1. Foregut - celiac artery (Adult: pharynx, esophagus, stomach, upper duodenum, respiratory tract, liver, gallbladder pancreas)
  2. Midgut - superior mesenteric artery (Adult: lower duodenum, jejunum, ileum, cecum, appendix, ascending colon, half transverse colon)
  3. Hindgut - inferior mesenteric artery (Adult: half transverse colon, descending colon, rectum, superior part anal canal)
