The splenic (or left colic) flexure is a sharp bend between the transverse and the descending colon in the left upper quadrant of humans. The left colic flexure is near the spleen, and hence called the splenic flexure. There are two colic flexures in the transverse colon — the other being the hepatic flexure in the right upper quadrant. The splenic flexure is a watershed region as is receives dual blood supply from the terminal branches of the Superior mesenteric artery and the Inferior mesenteric artery, thus making it prone to ischemic damage in cases of hypotension because it does not have its own primary source of blood.
