Anatomical terminology

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, as it is next to the liver, in the right upper quadrant. The splenic flexure is a watershed region as it 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 low blood pressure because it does not have its own primary source of blood. In the context of ischemia, the splenic flexure is sometimes referred to as Griffith's point, along with the upper rectum (Sudak's point).
