Ileal Artery

The ileal artery and its branches.

The Ileal Artery is a branch of the Superior Mesenteric Artery that supplies blood to the Ileum, a part of the Small Intestine. It is a crucial component of the Digestive System and plays a significant role in the absorption of nutrients.

Anatomy

The Ileal Artery originates from the Superior Mesenteric Artery, which is a major artery of the Abdomen. It travels towards the Ileum, giving off numerous branches that penetrate the intestinal wall to supply the mucosal and muscular layers. These branches form a series of arcades, which further give rise to straight arteries known as Vasa Recta.

Function

The primary function of the Ileal Artery is to provide oxygenated blood to the Ileum. The Ileum is responsible for the absorption of Vitamin B12, bile salts, and any other remaining nutrients not absorbed by the Jejunum.

Clinical Significance

Understanding the anatomy of the Ileal Artery is crucial in various surgical procedures involving the Small Intestine. It is also significant in the diagnosis and treatment of conditions such as Ischemic Colitis and Mesenteric Ischemia.
