Liver's functions

The liver is essential for metabolism and the function of all other organs. Between meals, the liver releases stored sugar into the bloodstream.

The liver is the biggest internal organ. The weight of the liver of an adult is approximately 1–1.5 kg. The liver is located on the right side of the abdominal cavity, under the diaphragm, protected by the ribs.

The liver regulates sugar metabolism. It stores sugar broken down from food and releases it into the bloodstream as needed. Insulin, secreted by the pancreas, increases the storage of sugar in the liver. Conversely, the counteracting hormone glucagon releases sugar from the liver into the bloodstream.

Liver has hundreds of different tasks

  • regulates lipid metabolism
