The inferior mesenteric vein is the largest tributary of the splenic vein, which arises from a number of merging veins from the spleen, pancreas, and part of the stomach. It is part of the system of hepatic veins which drain blood from the liver, and brings blood up from the descending colon, sigmoid colon, and the rectum.
