The hepatic portal system carries nutrients from the digestive system to the liver for processing and storage. These nutrients include glucose, amino acids, vitamins, and minerals absorbed from the food we eat.
The two veins are the hepatic portal vein and the splenic vein. They carry blood from the digestive organs and the spleen to the liver, allowing the liver to process and filter out nutrients, toxins, and other substances before the blood circulates through the rest of the body.
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.
The blood or the circulatory system carries oxygen and nutrients to the tissues and removes waste from them
Plants have various systems that help them carry out essential functions, such as photosynthesis, growth, and reproduction. These include the root system for absorbing water and nutrients from the soil, the shoot system for conducting water and nutrients to the leaves, and the reproductive system for producing seeds or spores. Additionally, plants have a vascular system composed of xylem and phloem for transporting water, nutrients, and sugars throughout the plant.
The cardiovascular system is another name for the circulatory system. It is the body system combining function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products
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.
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.
The two veins are the hepatic portal vein and the splenic vein. They carry blood from the digestive organs and the spleen to the liver, allowing the liver to process and filter out nutrients, toxins, and other substances before the blood circulates through the rest of the body.
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.

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.
Because its a "vein" but not 'artery' which carries blood to the organs or its parts.
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.
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.
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.
Your Heart, kidneys, lungs, and liver are the most important parts of your circulatory system.But other accessory bits also play their part, for example the Portal vein which connects the digestive system to the liver and spleen. [Hepatic portal vein in full.]And obviously, your brain, muscles and so on are connected to the circulatory system.
The circulatory system is responsible for absorbing nutrients from the digestive system. In addition, it works to carry these nutrients throughout the body.
