The IMA arises at L3 near the inferior border of the duodenum and supplies the hindgut organs, including the large intestine from the splenic flexure, descending colon, sigmoid colon, and the upper part of the rectum.

Detailed explanation-2: -Each of the above 3 portions has its own blood vessel, as follows: (1) the foregut is supplied by the celiac artery, (2) the midgut is supplied by the superior mesenteric artery, (3) the hindgut is supplied by the inferior mesenteric artery (Fig. 471).
