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 mesenteric artery; the superior branch anastomoses with the right colic artery.
