The liver (Hepar): Tasks
The liver (medical: Hepar) is a large and heavy element, it weighs about 1.2 to 1.8 kilograms. The liver takes a variety of tasks.
The liver is the largest gland of the human body and produces about 700 milliliters per day bile. Bile is later concentrated in the gallbladder and is mainly used for the Digestion of fats significant. Especially the bile acids contained in bile make it possible to digest fats. From the gallbladder bile passes through the large bile duct (common bile duct) into the duodenum. There she meets the of dietary fats (for example, triglycerides, cholesterol) and prepares them for further digestion. The fats can therefore be absorbed into the bloodstream through the intestinal wall.
Bile contains also bile pigments, such as bilirubin. These dyes in which the blood pigment hemoglobin is released can be seen from the breakdown of red blood cells.
The liver is also an important organ for the Metabolism of carbohydrates, proteins and fats. You can store carbohydrates as glycogen and dietary fats in the form of lipids. If necessary, it converts them from the storage form into a readily available form. Also, the liver from other compounds capable of forming the sugar glucose (so-called. Gluconeogenesis). In conjunction with the pancreas, the liver significantly regulates the level of blood sugar value.
Among the proteins which can make the liver include various blood components such as the transport protein albumin, clotting factors, and some hormones.
An important - and many well-known - function of the liver is the detoxification or transformation of endogenous and exogenous harmful substances into harmless. For example "detoxifies" the liver foreign substances such as drugs or toxins radicals and processed so that the body can excrete it. Also alcohol reduces the liver. At high alcohol consumption, the liver can adapt to their task - but only up to a certain extent. Permanent high alcohol consumption overwhelmed and damages the liver.
