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.
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.
In human anatomy, the superior mesenteric vein (SMV) is a blood vessel that drains blood from the small intestine (jejunum and ileum).Behind the neck of the pancreas, the superior mesenteric vein combines with the splenic vein to form the portal vein that carries blood to the liver.
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] Each of these arteries travel through the mesentery, within which they branch several times before reaching the gut. In humans, many of these ...
The foregut is supplied by the celiac trunk, the midgut is supplied by the superior mesenteric artery (SMA), and the hindgut is supplied by the inferior mesenteric artery (IMA). This division is established by the fourth week of development. After this, the midgut undergoes a period of rapid elongation, forcing it to herniate through the navel
The ileocolic artery is the lowest branch arising from the concavity of the superior mesenteric artery.It supplies the cecum, ileum, and appendix. It passes downward and to the right behind the peritoneum toward the right iliac fossa, where it divides into a superior and an inferior branch: the inferior gives rise to the appendicular artery and anastomoses with the end of the superior ...

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.
