Liver has metabolic function, secretion function, coagulation function, processing poison function and so on, it is the largest gland in human body. 1. Metabolic function: the liver is the largest metabolic organ in the human body, food is absorbed through the intestines, and the absorbed nutrients enter into the liver, which converts all kinds of nutrients into glycogen, and if the blood glucose is low, the liver decomposes the glycogen into glucose and enters into the blood. 2. Secretion function: the liver needs to secrete bile every day, bile is stored in the gallbladder, and bile is involved in the digestion and absorption of food. 3. Coagulation function: The blood clotting function of human body needs coagulation factors, and many kinds of coagulation factors are produced in the liver. 4. Toxin processing function: foreign toxins and metabolic toxins need to be phagocytosed by liver mononuclear macrophages and transformed into non-toxic substances to be discharged from the body. Warm reminder: If there is any abnormality in the liver examination, you should go to the hospital in time and standardize the treatment under the doctor’s guidance so as not to delay the condition.
