Question
What is portal system?
Solution
Portal system is the system of blood vessels consisting of the hepatic portal vein with its tributaries and branches. It exists between the digestive tract and liver.
It is the system when veins collect blood from some parts of body and pour it into some other parts of body instead of taking it directly to heart. The hepatic portal vein carries blood from intestine to the liver before it is delivered to the systemic circulation.
