Facts about Liver
The central area where the common bile duct, portal vein, and hepatic artery enter the liver is called the hilum or porta hepatis.
The fetal liver releases some blood stem cells that migrate to the fetal thymus, so initially the lymphocytes, called T-cells, are created from fetal liver stem cells.
Located on the right side of the upper abdomen below the diaphragm, the liver lies to the right of the stomach and makes a kind of bed for the gallbladder (which stores bile).
Liver allografts for transplant usually come from non-living donors who have died from fatal brain injury.
Many distinct regional traditions of Christmas are still practiced around the world, despite the widespread influence of Anglo-American Christmas motifs disseminated in popular culture.
Only 20 percent of an adult's liver is needed to serve as a liver allograft for an infant or small child.
Digestive organs: (1) esophagus, (2) throratic diaphragm, (3) stomach, (4) liver, (5) gallbladder, (6) duodenum, (7) pancreas, and (8) spleen.
The liver has the capacity to interconvert fuel molecules; for example, it can convert certain amino acids, and some other molecules like pyruvate and lactate, into glucose (a process called gluconeogenesis).
The bile produced in the liver is collected in bile canaliculi, which merge to form bile ducts.
The liver also performs several roles in lipid metabolism, including cholesterol synthesis and the production of triglycerides (fats).
The liver is the heaviest organ in the body: An adult human liver normally weighs between 1.7-3.0 kilograms (3.5-6.5 pounds).
More recently, adult-to-adult liver transplantation has been performed using the donor's right hepatic lobe, which comprises 60 percent of the liver.
The liver's regenerative ability is predominantly due to the hepatocytes' ability to act as unipotential stem cells (i.e.
Soft, pinkish-brown, and boomerang-shaped, the liver is the second largest organ in the body (after the skin), and the largest internal organ.
Liver regeneration is also at the basis of modern transplant techniques.
The death of the liver cells can be caused by a number of factors, including viral hepatitis, alcoholism, or contact with other liver-toxic chemicals.
The liver is among the few internal human organs capable of natural regeneration of lost tissue; as little as 25 percent of remaining liver can regenerate into a whole liver again.
The liver contributes to the regulation of blood glucose levels, storing excess glucose as glycogen, and releasing glucose into the bloodstream when levels decrease.
The duct, vein, and artery divide into left and right branches, and the portions of the liver supplied by these branches constitute the functional left and right lobes.
The liver is a large vertebrate organ positioned in the upper region of the abdominal cavity, below the diaphragm.
The hepatic artery, which contributes about 25 percent of blood flow to the liver, conveys oxygenated blood to the liver.
The liver cells, therefore, perform the glucose storage and release primarily for the benefit of other organs.
Hepatocytes (liver cells) comprise about 60 percent of liver tissue; they participate in numerous metabolic and secretory functions.
At any given moment, the liver contains about one pint of blood or approximately 13 percent of the body's total blood supply.
Mammalian and avian livers may be part of the human omnivore's diet: Culinary products throughout the world include liver pвtй, Leberwurst, Braunschweiger, foie gras, chopped liver, liver and onions, leverpostej, and liver sashimi.
The bilirubin accumulates from the breakup of the hemoglobin present in defunct red blood cells; during normal function, the liver removes bilirubin from the blood and excretes it through bile.
The liver can be considered an altruistic organ—its metabolic activities essential for providing fuel to the brain, muscle, and other peripheral organs, often at the expense of its own energetic needs (Stryer 1994).

The central area where the common bile duct, portal vein, and hepatic artery enter the liver is called the hilum or porta hepatis.
Cirrhosis refers to the formation of fibrous scar tissue in the liver, which replaces dead liver cells, leading to a progressive loss of liver function.
The liver also plays a role in aspects of lipid metabolism, such as cholesterol synthesis.
The liver, and associated veins, of a 24- or 25-day-old human embryo, as seen from the ventral surface.
Hepatitis, or inflammation of the liver, is caused mainly by a range of viruses, but may also be triggered by some poisons, autoimmunity, or hereditary conditions.
Mammalian and avian livers may be part of the human omnivore's diet: Culinary products throughout the world include liver pвtй, Leberwurst, Braunschweiger, foie gras, chopped liver, liver and onions, leverpostej, and liver sashimi.
