What is the main function of the liver in the human body?

The primary function of the liver related to the removal of toxins from digestion is crucial for maintaining overall health. The liver processes nutrients that are absorbed from the digestive tract and plays a vital role in detoxifying harmful substances. When food is digested, it heads to the liver through a network of veins called the portal vein. The liver then breaks down various toxins, drugs, and metabolites, ensuring these substances are either transformed into harmless forms or excreted from the body. This detoxification process is essential for preventing damage to other organs and maintaining homeostasis.

In addition to detoxification, the liver also has several other important functions, such as producing bile to aid in digestion, storing vitamins and minerals, and metabolizing fats and carbohydrates. However, its role in detoxification is particularly significant as it directly impacts how the body handles substances that could be harmful.
