The inferior pancreaticoduodenal artery is a branch of the superior mesenteric artery. [2] These arteries, together with the pancreatic branches of the splenic artery , form connections or anastomoses with one another, allowing blood to perfuse the pancreas and duodenum through multiple channels.
These vessels anastomose with the pancreatic branches of the superior and inferior pancreaticoduodenal artery that are given off by the gastroduodenal artery and superior mesenteric artery respectively.
The transition between these sources is important as it demarcates the foregut from the midgut. Proximal to the 2nd part of the duodenum (approximately at the major duodenal papilla – where the bile duct enters) the arterial supply is from the gastroduodenal artery and its branch the superior pancreaticoduodenal artery.
Pancreaticoduodenal artery (arteries to the pancreas and duodenum) can refer to: . Superior pancreaticoduodenal artery; Inferior pancreaticoduodenal artery; In case of a coarctation of the aorta located between the celiac trunk and the superior mesenteric artery, the anastomosis between these arteries can provide an alternative route for blood flow, called the pancreaticoduodenal arcade
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.

The large intestine is primarily supplied by the right colic artery, middle colic artery, and left colic artery. They do not supply the duodenum of the small intestine. The duodenum is primarily supplied by the inferior pancreaticoduodenal artery and superior pancreaticoduodenal artery.
