The primary function of the human liver is to detoxify and metabolize substances essential for survival. It plays a critical role in various bodily functions, including the synthesis of proteins, the production of biochemicals necessary for digestion, and the regulation of blood sugar levels. The liver helps process nutrients absorbed from the digestive tract and manages waste products, ensuring they are either excreted or recycled. Additionally, the liver stores essential vitamins and minerals and produces bile, which aids in the digestion of fats. Due to its many roles, the liver is crucial for maintaining overall health.
