A cardiac vein, from a network of vessels onthe truncus arteriosus. y^ 2. The hepatic portal vein is a wide vein which runsin the mesentery and joins the anterior abdo-minal vein at its point of division into right andleft branches; giving off, before doing so, a branchto the left lobe of the liver. It carries to theliver the blood from the walls of the alimentarycanal, and is formed by the union of the follow-ing veins: i. The gastric vein, from the stomach. ii. Intestinal veins, from the whole length of theintestine, both small and large. iii. The splenic vein, from the spleen: this usuallyjoins one of the intestinal veins. C.
