Chapter 20, Problem 21RQ
Summary Introduction
To review:
Two large tributaries that form the hepatic portal vein, and the role of hepatic portal circulation.
Introduction:
The blood from the organs and tissues gets drains in the specific veins. There exists a perfect and proper labor division for the transportation of venous blood in the body. The venous blood from the intestine is rich in the nutrients and digested food. There exists a specific venous system for the drainage of this blood.

Students have asked these similar questions
(a) What blood vessels contribute to the formation of the hepatic portal circulation? (b) Why is a portal circulation a “strange” circulation?
Tell which two vessels are missing from the following sequence: Tracing the drainage of venous blood from the small intestine, blood enters the superior mesenteric vein, hepatic vein, inferior vena cava, and right atrium. (a) coronary sinus and left atrium, (b) celiac and common hepatic veins, (c) internal and common iliac veins, (d) hepatic portal vein and liver sinusoids.
The hepatic portal vein receives blood from four major veins. What are the major veins?
