Functions of the Liver:
The liver performs several important functions, including:

2. Detoxification: The liver is responsible for removing toxins and harmful substances from the body. It converts ammonia, which is toxic, into urea, which is eliminated from the body through urine.

3. Storage: The liver stores several important substances, including vitamins, minerals, and glucose. It also stores bile, which is essential for the digestion of fats.

4. Secretion: The liver secretes bile, which is necessary for the digestion of fats.

5. Immune function: The liver plays an important role in the immune system. It produces immune factors that help to fight infection and remove harmful substances from the body.

In conclusion, the liver is the largest gland in the human body and performs several vital functions. Its unique structure and functions make it an essential organ for the maintenance of good health.
