What are the names of the two veins that carry nutrient-rich blood from the digestive organs to the liver for 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.
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
What systems do plants have?
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.
What is the human cardiovascular system?
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
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.
What are the names of the two veins that carry nutrient-rich blood from the digestive organs to the liver for 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.
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?
The hepatic portal circulation functions to carry nutrient-rich blood from the digestive organs to the liver for processing and storage. It allows the liver to regulate nutrient levels in the blood before it is distributed to the rest of the body.
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.
How many body parts are conected to the cirultory system?
There are three main body parts connected to the circulatory system: the heart, blood vessels, and blood. The heart pumps blood through the blood vessels, which then carry oxygen and nutrients to all parts of the body and remove waste products.
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.
