What is the primary function of the liver?
During my physical examination, the doctor mentioned that my liver was somewhat unhealthy. What are the main functions of the liver?
Doctor's answer (1)
The liver is the largest solid gland organ in the human body, and its primary functions include the following aspects:
1. Metabolic storage: The liver participates in the metabolism and storage of nutrients and energy, such as the synthesis and storage of glycogen, fats, and cholesterol, making it an important organ for maintaining stable blood glucose levels.
2. Bile formation: The liver produces bile, which is transported through bile ducts to the gallbladder for storage. During meals, bile is released into the intestines, aiding in the digestion and absorption of fats.
3. Detoxification: The liver has powerful detoxification capabilities, effectively degrading and removing harmful substances from the bloodstream to protect the body from toxins.
4. Substance metabolism: The liver participates in water and electrolyte metabolism, maintaining fluid balance, and is involved in metabolic processes of substances such as proteins, fats, and amino acids.
5. Coagulation mechanism: The liver synthesizes various clotting factors, playing a vital role in maintaining normal blood coagulation function.
6. Immune regulation: Reticuloendothelial cells within the liver can phagocytize, isolate, eliminate, or modify antigens, participating in the body's immune regulation processes.
7. Circulatory regulation: The liver also participates in the regulation of the circulatory system, helping to maintain normal blood flow and distribution.
Therefore, liver health should be prioritized, avoiding detrimental habits such as excessive alcohol consumption and drug abuse to preserve normal liver function.
