What is the primary function of the liver in terms of digestion?

The liver plays a crucial role in digestion primarily through its function of removing toxins from the bloodstream. As blood flows through the liver, it filters out harmful substances, including drugs, alcohol, and metabolic waste products, which are either broken down by liver enzymes or prepared for excretion. This detoxification process is essential for maintaining overall health and allowing other digestive processes to function optimally.

While the liver does produce some important substances related to digestion, such as bile, which helps emulsify fats, its predominant role in digestion is tied to detoxifying the blood and ensuring that nutrients can be absorbed and utilized effectively by the body. Consequently, the liver indirectly supports the digestive system by maintaining a safe and balanced internal environment.
