THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The superior mesenteric artery provides blood to the pancreas and parts of the small intestine and large intestine.

Detailed explanation-2: -Pathophysiology. The celiac axis and superior mesenteric artery (SMA) supplies all of the blood to the small intestine. Branches of the celiac axis supply blood to the stomach, duodenum, pancreas, and liver.

Detailed explanation-3: -Superior mesenteric artery syndrome (SMA syndrome) is a digestive condition that occurs when the part of the small intestine that connects to the stomach is pinched by two arteries.

Detailed explanation-4: -The SMA and IMA are linked through the marginal artery of Drummond and may also be connected through the arc of Riolan (Fig. 11). The marginal artery of Drummond represents the major collateral arcade between the two mesenteric vessels.
