What are the PORTAL systems in the human body?
1) Hepatic Portal Vein 2) Renal Portal System 3) Hypothalamic-Hypophyseal Portal System not so sure about number 2 :P
What is hepatic portal?
The hepatic portal system basically consists of the hepatic portal artery, responsible for taking the products of digestion from the small intestine to the liver, where they are broken down further, cleaned of any microbes, and sent to all the body cells via the hepatic portal vein.
Is there any other portal vein in your body except Hepatic portal vein?
Portal is a video game.
Which vein carries nutrient-rich blood from the digestive system to the liver?
The liver is connected to two blood vessels, one called the hepatic artery and the other the portal vein. The portal vein carries nutrients digested from the gastro intestinal track.See the related links for more information.
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.
Is hypertension and portal hypertension the same?
No. Portal Hypertension is specific hypertension in the portal system while general hypertension is the primary hypertension. Portal hypertension happens when there is high pressure in the portal circulation or the circulation in the Liver and lower body organs.
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 do oxygen and particles of digested food get into the cells of your body?
Oxygen and particles of digested food get into the cells from the small intestine, from there they drain into the hepatic portal vein. The hepatic portal vein goes to the liver to filter out nutrients required and excesses are metabolized and converted.
What is the main purpose of the hepatic-portal circulation?
Hepatic Portal Circulation The veins of the hepatic portal circulation drain the digestive organs, spleen, and pancreas and deliver the blood to the liver via hepatic portal vein. As blood percolates through the liver, some of the nutrients are stored or processed in various ways for release to the general circulation. The liver in turn is drained by the hepatic veins that enter the inferior vena cava. The inferior mesenteric vein, draining the distal part of the large intestine, joins the splenic vein, which drains the spleen, pancreas and stomach. The splenic vein and the superior meseteric vein, which drains the small intestine and the proximal colon, unite to form the hepatic portal vein. The left gastric vein, which drains the lesser curvature of the stomach, drains directly into the hepatic portal vein.

Explain what is portal circulation?
portal circulation refers to the circulation of the blood from the small intestine to the liver, via the portal vein. Blood flow to the liver is unique in that it receives oxygenated and de-oxygenated blood. Blood passes from branches of the portal vein through cavities between "plates" of hepetocytes called sinusoids. Blood also flows from branches of the hepatic artery and mixes into the sinusoids to supply the hepatocytes with oxygen. This mixture percolates through the sinusoids and collects in a central vein which drain into the hepatic vein. The hepatic vein subsequently drains into the inferior vena cava. =)
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.
Where do the nutrients that pass through villi go?
They will pass through the hepatic portal vein to get processed by the liver before heading to the rest of the body.
