The Hepatic portal system collects the blood from the spleen, stomach, pancreas and intestine which reaches the liver.
In this process the, system of portal veins divides into capillaries which again combine to form hepatic veins.
The functions of the hepatic portal system
Hepatic portal system carries blood to the liver where the excess glucose is absorbed and stored in the form of glycogen.
Liver also converts the toxic substances to non-toxic compounds thus hepatic portal system plays an important role in preventing the spread of poisons to the body which get absorbed by the digestive system.
