What is the hepatic portal system? Explain.

Text Solution

Verified by Experts

The deoxygenated blood passes through the hepatic portal veins and transports blood from the digestive tract and spleen to the liver.
• Hepatic portal system starts from the capillaries in the gastrointestinal tract and ends at the capillaries in the liver.
• Since the blood flows in the system from one capillary to another capillary through veins, it is called portal system.
