The liver is thought to be responsible for up to 500 separate functions, usually in combination with other systems and organs. Currently, no artificial organ or device is capable of reproducing all the functions of the liver. Some functions can be carried out by liver dialysis, an experimental treatment for liver failure. The liver also ...
The necessity of such a system is demonstrated by what happens when the system breaks down, as seen when advanced hepatic fibrosis in cirrhosis leads to hepatic encephalopathy in the brain owing to the blood being loaded with ammonia and other substances not conducive to brain function. Blood flow to the liver is unique in that it receives both ...
Albumin, carries thyroid hormones and other hormones, particularly fat soluble ones, fatty acids to the liver, unconjugated bilirubin, many drugs and Ca 2+ Ceruloplasmin, carries copper; Transcortin, carries cortisol, aldosterone and progesterone; Haptoglobin, carries free hemoglobin released from erythrocytes
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
The function and role of quiescent hepatic stellate cells is unclear. Recent evidence suggests a role as a liver-resident antigen-presenting cell, presenting lipid antigens to and stimulating proliferation of NKT cells. [7] When the liver is damaged, stellate cells can change into an activated state.
Lipid metabolism is the synthesis and degradation of lipids in cells, involving the breakdown and storage of fats for energy and the synthesis of structural and functional lipids, such as those involved in the construction of cell membranes. In animals, these fats are obtained from food and are synthesized by the liver. [1]
Although further experiments are needed to parse out the physiological significance of the connection between the glymphatic circulation, calcium signalling, and paravascular lipid transport in the brain, the findings point to the adoption of a function in the CNS similar to the capacity of the intestinal lymph vessels to carry lipids to the liver.
The liver has many functions some of which are important to digestion. The liver can detoxify various metabolites; synthesise proteins and produce biochemicals needed for digestion. It regulates the storage of glycogen which it can form from glucose (glycogenesis). The liver can also synthesise glucose from certain amino acids. Its digestive ...
