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.

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

**Gastrointestinal Tract Divisions**
Foregut	Midgut	Hindgut
trachea, respiratory tract, lungs oesophagus (osophagus} stomach liver gallbladder ( and bile ducts) pancreas (dorsal & ventral) upper duodenum	lower duodenum small intestines (jejunum, ileum) cecum appendix Ascending colon proximal 2/3 of transverse colon	distal 1/3 of transverse colon descending colon sigmoid colon rectum Upper anal canal Urogenital sinus
