Portal is a video game.
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.
1) Hepatic Portal Vein 2) Renal Portal System 3) Hypothalamic-Hypophyseal Portal System not so sure about number 2 :P
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 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.
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.
Humans have a hepatic portal system that brings all the venous flow from the digestive system into the liver. Reptiles have a renal portal system, which brings blood from internal organs to their kidneys, mostly because their digestive tract and urinary tract only have the cloaca to eliminate waste from their body. Since humans have separate systems for eliminating waste, the anus and urethra, the human body, like all other mammals, developed a hepatic portal system.

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.
They will pass through the hepatic portal vein to get processed by the liver before heading to the rest of the body.
The hepatic portal vein is formed by the union of (a) splenic vein, which drains the spleen, pancreas, greater curvature of stomach and (b) superior mesenteric, which drains the small intestine and ascending colon. The gastric vein, which drains the lesser curvature of the stomach, empties directly into the hepatic portal vein.The hepatic portal vein is formed by the union of (a) the splenic vein, which drains the spleen, part of the pancreas, and the stomach & (b) superior mesentic vein, which drains the small intestine and transverse colon. The left gastric vein, which drains the lesser curve of the stomach, empties directly into the hepatic portal vein.
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.
It serves the body in three ways. •Removes excess glucose and stores it in the liver as glycogen. •Detoxifys blood. •Removes various poisonous substances present in blood.
