Explain what is portal circulation?

Answer 1

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. =)

Answer 2

Human circulatory system can be divided into two, pulmonary circulation system and systemic circulation system. First, oxygenated blood is transported from the lung to the heart by pulmonary vein. Then it is transported to all part of the body by aorta-vein-venules-capillaries. It becomes deoxygenated blood after oxidation of food at the cell body. The blood is transported back to the heart from the capillaries of the cell body by arterioles-artery-vena cava. Next, is is transported back to the lung for gaseous exchange by pulmonary artery. The whole circulation is repeated again and again until the end of your life...=)muahh

Answer 4

A portal circuit is found the cardiovascular system. Usually, very small arteries called arterioles lead into a capillary bed and tiny veins called venules come off. In a portal system veins come into a capillary bed and come off. This system is very slow moving since the pressure from the artery side is lacking. There are only two of these in the human body: one in the liver and hypophyseal area.
