Chapter 24, Problem 4RQ
Summary Introduction
Introduction:
The hepatic portal vein is the blood vessel that brings the nutrient rich deoxygenated blood from the digestive tract to the liver. The substances absorbed in the digestive tract are processed in the liver before it enters the systemic circulation. The toxic substances are eliminated in the liver that can enter the systemic circulation to cause damage to the body.
