The name "liver" is the word "oven", t. The liver has the highest temperature of all organs of the living body. What is the reason for this?.

Most likely in that in the liver per unit mass the highest amount of energy production occurs. Up to 20% of the whole liver cell mass is occupied by the mitochondria "cell power stations", which continuously form ATP, which distributes throughout the body, according to the Internet publication for girls and women aged 14 to 35 Pannochka. Net All liver tissue consists of lobules. Lobule is a structural and functional unit of the liver. The space between the hepatic cells is the bile ducts. In the center of the lobule passes the vein, the interlobular tissue is filled with vessels and nerves.

The liver as an organ consists of two unequal large parts: the right and left. The right lobe of the liver is much larger than the left, so it is so easily probed in the right hypochondrium. The right and left lobes of the liver are separated from above by a crescent ligament, on which the liver is "suspended", and at the bottom the right and left lobes are separated by a deep transverse furrow. In this deep transverse furrow there are so-called gates to the liver at this point the liver enters the vessels and nerves, the hepatic ducts that outflow bile. Small hepatic ducts gradually combine into one common. Common bile duct, includes the duct of the gallbladder - a special reservoir in which bile accumulates. The common bile duct empties into the 12-colon, almost in the same place where the pancreatic duct enters it.

Blood circulation of the liver is not like the circulation of other internal organs. Like all organs, the liver is supplied with arterial blood, oxygenated from the hepatic artery. Through it flows venous blood, poor in oxygen and rich in carbon dioxide, and flows into the portal vein. However, in addition to this usual for all circulatory organs, the liver receives a large amount of blood flowing from the entire gastrointestinal tract. All that is absorbed in the stomach, 12 duodenum, the small and large intestine, gathers into a large portal vein and flows into the liver. The goal of the portal vein is not to supply the liver with oxygen and to rid itself of carbon dioxide, but to pass through the liver all the nutritious (and not nutritious) substances that are absorbed throughout the gastrointestinal tract. First through the portal vein they pass through the liver, and then the liver, undergoing certain changes, are absorbed into the total blood flow.

The portal vein accounts for 80% of the blood obtained by the liver. The blood of the portal vein has a mixed character. It contains both arterial and venous blood flowing from the gastrointestinal tract. Thus, in the liver there are 2 capillary systems: the usual, between the arteries and veins and the capillary network of the portal vein, sometimes called the "wonderful network". The ordinary and capillary miraculous network are interconnected.
