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.

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.

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.

The Common Symptoms Of Liver Problems?
Cirrhosis is a disease of the liver that is caused by liver cells that are damaged. The damaged liver cells can not repair itself and the dying cells form scar tissue. The scar tissue builds up over time, and the blood can't flow properly through the liver. The liver filters poisons and waste in the blood. The scar tissue prevents the blood from being filtered properly. The waste and poisons build up in the body and can lead to death. Cirrhosis causes symptoms of liver problems that include vomiting blood, dark brown urine and unintended weight loss. Other symptoms include loss of appetite, fatigue and a yellowing of the skin called jaundice. Cirrhosis can be caused by an infection of the liver called hepatitis. Eating or drinking harmful chemicals can cause cirrhosis. The most common cause of cirrhosis is drinking too much alcohol. The diagnosis of cirrhosis include laboratory test, liver biopsy and ultrasound. Treatments focus on preventing further damage to the liver. The main artery to the liver is called the portal vein. If scar tissue blocks the vein then pressure builds and is called Portal Hypertension. This condition will cause a build up of waste and poisons in the body. When the portal vein can't send blood flow through the kidneys, it travels back through the stomach, esophagus and intestines. The veins become swollen due to the heavier volume of blood and are at-risk of breaking open. This condition can be fatal. The treatment focuses on medication to prevent the blood vessels from breaking and medication to lower the blood pressure. If the medication doesn't work, then surgery may be needed to stop the blood flow to broken blood vessels. One technique is to interrupt the blood flow to swollen veins with a tube. The tube is attached where the esophagus and stomach meet, and extends to the specific swollen veins. The best way to prevent liver disease is to limit the use of alcohol. Ask your doctor for diet and exercise recommendations. Consult your doctor before taking vitamins and non-prescription medications. Learn about good nutrition and relaxing techniques to improve your quality of life.
