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.
Superior mesenteric artery and its branches in humans Inferior mesenteric artery and its branches in humans. The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta. [1]
The superior mesenteric vessels are composed of the superior mesenteric artery and the superior mesenteric vein.. In human anatomy, the superior mesenteric artery arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
The inferior mesenteric vein connects in the majority of people on the splenic vein, but in some people, it is known to connect on the portal vein or the superior mesenteric vein. Roughly, the portal venous system corresponds to areas supplied by the celiac trunk, the superior mesenteric artery, and the inferior mesenteric artery.

The ileal arteries are 12 branches of the superior mesenteric artery [1] which supply blood to the ileum. [ citation needed ] They arise from the left side of the superior mesenteric artery. [ 1 ]
The superior mesenteric artery arises from the aorta at the level of the transpyloric plane and emerges between the head and neck of the pancreas. [8] The superior mesenteric vein is joined by the splenic vein to form the portal vein at the level of the transpyloric plane. [2] [8]
