right colic artery

The right colic artery may arise directly from the superior mesenteric artery (SMA) but often arises from a common trunk with the ileocolic artery or middle colic artery.

It courses to the right to the ascending colon and divides into a descending branch that supplies the lower portion of the ascending colon and anastomoses with the colic branch of the ileocolic artery, and an ascending branch which supplies the upper portion of the ascending colon and anastomoses at the hepatic flexure with the right branch of the middle colic artery. It contributes to the marginal artery of Drummond.
