Question
Chapter 19, Problem 17RQ
Summary Introduction
To review:
a. The blood vessels, which form the hepatic portal system.
b. The uniqueness of the HPS (hepatic portal system).
Introduction:
The HPS is a portal system of veins and capillaries. The system functions to carry blood from different parts of the GI (Gastrointestinal Tract) and spleen to the liver. Liver functions to process the nutrients present in the blood before returning the blood directly to the heart.

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.
Cirrhosis of the liver, a disease commonly associated with alcoholism, obstructs blood flow through hepatic blood vessels. As a result, blood backs up and capillary pressure greatly increases in organs drained by the hepatic portal system. What effects might this increasing capillary pressure produce, and which organs would it affect?
