The superior mesenteric arterys initial course is forwards and downwards and it travels posterior to the neck of the pancreas and the splenic vein.

It originates on the anterior surface of the aorta at the level of the l1 vertebrae approximately 1 cm inferior to the celiac trunk and superior to the renal arteries. Located under this portion of the superior mesenteric artery between it and the aorta are the following. The sma is the artery to the midgut.

The mesentery is a translucent sheet that suspends the intestines and other abdominal viscera from the posterior body wall. Arising several centimetres above the termination of the aorta is the inferior mesenteric artery which branches to supply the lower part. This artery branches off the abdominal aorta and supplies oxygenated blood to the pancreas and the lower parts of the intestine.

It arises from the abdominal aorta and supplies arterial blood to the organs of the midgut which spans from the major duodenal papilla of the duodenum to the proximal 23 of the transverse colon. The arterial supply arises from the superior and inferior mesenteric arteries. Its branches supply the small intestine and part of the large intestine.

The mesentery contains numerous arteries veins and lymphatic vessels that supply and drain the intestines. Marginal artery of drummond forms a continuous arterial. Uncinate process of pancreas this is a.
