The (also known as the ileal artery ) is a branch of the superior mesenteric artery (SMA) that specifically supplies oxygenated blood to the ileum , the final and longest section of the small intestine . Anatomical Role & Distribution
The ileal artery is part of an intricate network that includes the (supplying the distal ileum and cecum) and the marginal artery of Drummond , which provides collateral circulation between the SMA and the inferior mesenteric artery. This redundancy is critical for protecting the bowel against ischemia (lack of blood flow) if one branch becomes blocked. arteria ileum

From the last arcade, small, straight vessels called vasa recta extend directly into the intestinal wall to provide localized blood flow. Anatomy, Abdomen and Pelvis: Ileocolic Artery - StatPearls
It arises from the left side of the superior mesenteric artery .
These arteries pass between the layers of the mesentery. Before reaching the intestinal wall, they divide and join with adjacent branches to form a series of loops or arterial arcades .
