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
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 body systems main function is to carry oxygen and nutrients to the tissues and remove waste from them?
The blood or the circulatory system carries oxygen and nutrients to the tissues and removes waste from them
Do plants have specialized tissues to carry nutrients upward?
YES..., they carry nutrients upward through their stem to distribute the products of photosynthesis.
Does the circulatory system carry nutrients to the cells?
No, lymph doesn't do that. Blood (specifically red blood cells), a part of the cardiovascular system, carries nutrients and oxygen to the cells.
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 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.

hepatic portal and portal veins
Does the hepatic portal vein carry oxygen-rich blood?
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.

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.
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.
Where is the hepatic-portal circulation situated?
between the left gastric and lienal The portal vein(vena portæ) is about 8 cm. in length, and is formed at the level of the second lumbar vertebra by the junction of the superior mesenteric and lienal veins, the union of these veins taking place in front of the inferior vena cava and behind the neck of the pancreas. It passes upward behind the superior part of the duodenum and then ascends in the right border of the lesser omentum to the right extremity of the porta hepatis, where it divides into a right and a left branch, which accompany the corresponding branches of the hepatic artery into the substance of the liver. In the lesser omentum it is placed behind and between the common bile duct and the hepatic artery, the former lying to the right of the latter. It is surrounded by the hepatic plexus of nerves, and is accompanied by numerous lymphatic vessels and some lymph glands.
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.
What is the role of circulatory system in nutrients?
The circulatory system is responsible for absorbing nutrients from the digestive system. In addition, it works to carry these nutrients throughout the body.
How are pulmonary veins different from the rest of the veins in the body?
Pulmonary veins are the only ones that carry properly oxygenated blood. The reason is say properly oxygenated is that some would argue that the Hepatic Portal Vein's primary function is to collct nutrients and does not completely surrender all its oxygen, remaining partially oxygenated.
