The liver gets a dual blood supply from the hepatic portal vein and hepatic artery. Supplying approximately 75% of the liver's blood supply, the hepatic portal vein carries venous blood drained from the spleen, gastrointestinal tract, and its associated organs. The hepatic arteries supply arterial blood to the liver, accounting for the remainder of its blood flow . Oxygen is provided from both sources; approximately half of the liver's oxygen demand is met by the hepatic portal vein, and half is met by the hepatic arteries.

∙ 13y agoIn the circulatory system, veins (from the Latin vena) are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. Veins differ from arteries in structure and function; for example, arteries are more muscular than veins and they carry blood away from the heart.

∙ 10y agoThe hepatic portal vein is one of the body's main blood vessels. It transports de-oxygenated blood from the gut to the liver. "Hepatic" refers to the liver, and the portal vein is very important in carrying nutrients to the liver for processing.

What is the source of blood in the hepatice portal system?
The source of blood in the hepatice portal system is the blood in the circulatory system itself. The hepatic portal is not seperate from the rest of the system, it is just a minor detour that takes blood from the digestive organs towards the liver where it can get further processing.
What is the hepatic system?
The hepatic (portal) system refers to the blood vessels that carry blood from the intestines, stomach, pancreas and spleen to the liver. Blood containing nutrients or drugs absorbed from the intestine is transported by the hepatic portal system to the liver for metabolism before distribution to the rest of the body.
What are the names of the two veins that carry nutrient-rich blood from the digestive organs to the liver for processing?
hepatic portal and portal veins
Why doesn't the hepatic portal vein carry fat into the small intestine?
Because its a "vein" but not 'artery' which carries blood to the organs or its parts.
What provides access for blood vessels entering and leaving the liver?
Blood to be processed by the liver enters via two sources: * the hepatic artery which delivers oxygenated blood from the general circulation * the portal vein from the small intestine (deoxygenated blood) Blood exits through the hepatic vein to the heart.
Which blood vessel takes oxygenated blood away from the heart?
The blood vessel that carries out this task is called the Hepatic Portal Vein
What is the vein that carries pure blood?
The pulmonary vein carries oxygenated blood from the lungs to the heart.
How the anatomical design of the hepatic circulation serves its function?
You have capillaries in the gastrointestinal tract. The capillaries unite to form the veins. You have again formation of the capillaries in the liver. Here the blood has to pass through the sinusoids to the central vein. The blood is accompanied by blood from the hepatic artery. The portal blood carry the nutrients. The hepatic artery carry the oxygen. The liver cells are metabolically active. They need both to perform the desired function. So you have very unique arrangement in the liver. So you have capillaries - veins - capillaries in portal circulation.
What is the function of the hepatic portal circulation?
Portal circulation involves the liver, and the portal vein (unlike most organs, where an artery carries blood TO the organ) carries blood TO the liver from the intestines. The liver helps to process nutrients, and enzymatically convert medication and drugs into both active and inactive by-products. The largest vessel in this system is the portal vein, followed by the hepatic veins, which carry blood from the liver to the inferior vena cava and back to the heart. The function of the hepatic portal circulation is to : collect absorbed nurtients for metabolic processing or storage.
Source of blood in the hepatic portal system?
Portal vein receives blood from two major veins, Superior mesenteric vein that drains the entire small bowel and splenic vein which drains the entire large bowel and spleen. Portal vein supplies about 60% of the total blood flow to the liver.
What is the blood vessel that carries the blood to the lungs called?
pulmonary vein carries oxygenated blood to heartAll the vessels that carry blood back to the heart are called veins, all veins carry deoxygenated blood to the heart but pulmonary vein carries oxygenated blood because blood becomes oxygenated in lungsSome veins carry the blood from an organ to the other organ then to the heart. These are called portal veins such as hepatic portal vein and (in reptiles, amphibians and aves) renal portal vein.
What do hepatic arteries carry blood to?
The liver.
