Solution
The correct option is B Hepatic portal vein
Generally, the capillaries join together to form a vein. The hepatic portal vein is unique because it ends and starts with capillaries.
The hepatic portal vein is formed by the convergence of the superior mesenteric vein and the splenic vein that carries blood from the spleen and intestines and enters the liver where it again breaks into fine capillaries.
