How is duodenum blood supply?

Because duodenum is developing from foregut and midgut, it is supplied by branches of celiac and superior mesenteric arteries. Proximal: Superior pancreaticoduodenal artery, branch of gastroduodenal artery (first branch of proper hepatic artery). Distal: Inferior pancreaticoduodenal artery (branch of superior mesenteric artery [SMA]).
