The portal vein is formed by the merger of the superior mesenteric vein and the splenic vein.

The portal vein system plays a vital role in the metabolism and detoxification of nutrients and drugs absorbed from the digestive tract. Any obstruction or damage to the portal vein system can result in liver disease and other complications.
