The pathology of the liver and biliary system

Liver Disease, gallbladder and biliary tract are among the most common diseases of the digestive system. The value of this disease depends not only on health, but also social aspects in connection with the part of its detectability of working age, and high rates of temporary and permanent disability.

Early diagnosis and treatment of diseases of the biliary system is of great clinical importance because of the possibility of transfer of functional disorders of the digestive system to the organic pathology.

The liver is the largest gland of the digestive system and performs multiple functions, of which the most important are the metabolic (participate in the metabolism), bariyernaya (Protective), excretory (excretory). In the liver, the synthesis of proteins (formed blood proteins), it happens and most intense protein breakdown. Also, the liver plays an important role in hormone metabolism, vitamins. Participation in the pigment of the liver metabolism is the formation of bilirubin, seizure of his blood, conjugation and excretion (allocation) it in bile.

Due to the excretory function of the liver secretes the bile compounds, synthesized by the liver itself and captured it from the blood. In the liver and neutralization of toxic products, coming from outside or produced during metabolism.

The most common clinical sign of liver disease - the appearance of jaundice staining of the skin (jaundice).

The occurrence of jaundice caused by metabolic disorders of bilirubin, which is formed by the decay of red blood cells and the destruction of part of a red blood cell - heme pigment. There are three types of jaundice: nadpechenochnaya (associated with poor education and increased degradation of red blood cells in diseases of the blood and blood-forming system); hepatic (associated with damage to the liver cells in hepatitis); subhepatic (in the pathology of the common bile duct in cholelithiasis). In these diseases diagnostic importance is the predominant fraction of bilirubin in the biochemical analysis of blood. Having one does not allow to recognize jaundice disease

It is therefore necessary to analyze other clinical symptoms, Hepatitis help differentiate from other causes of jaundice.
