Answer

The middle colic artery forms an arcade with the left colic artery, which is a branch of the inferior mesenteric artery. This arcade, termed the marginal artery of Drummond, lies in the mesenteric border adjacent to the colonic wall. The marginal artery gives off vasa recta to the transverse colon, the splenic flexure, and the descending colon. The sigmoid colon is supplied by branches of the left colic artery, as well as by two to four sigmoidal arteries, which are branches of the inferior mesenteric artery.
