What is the portal system? define the portal system in detail? Provide a specific example and describe the importance of the portal system to your examples?

Portal system is a system of blood vessels which begins and ends in capillaries. It plays major role in directing blood from gastrointestinal tract to the liver before taking to heart. It is called as hepatic portal system, a part of body's filtration system which plays important role in carrying nutrients from digestion to the liver to store and metabolize. Portal system is major inevitable system of lower vertebrates which comprise of areas of the venous system that begin in capillaries in tissues and join to form veins, which divide to produce another capillary network en route to the heart. There are two major portal systems:

• Hepatic portal system and
• Renal portal system.

Though the function of the renal portal system is less clear, it involves two veins that pass from the caudal vein which further break up into capillaries, to the kidney

Portal system is important in transporting products of one region directly to another region in relatively high concentrations. Blood along with nutrients of the specific portal system are spread around the body if it involves the heart.
