What is the main function of the liver?

The liver plays a crucial role in detoxification and metabolism, making it essential for maintaining overall health. Its primary functions include processing nutrients absorbed from the digestive tract, detoxifying harmful substances, and producing important biochemicals necessary for digestion, such as bile. The liver also regulates various metabolic processes, including the conversion of glucose to glycogen for storage and the synthesis of proteins.

This metabolic activity is vital for energy management and nutrient balancing within the body, ensuring that the body effectively utilizes and stores nutrients. By detoxifying chemicals and metabolizing drugs, the liver protects the body from toxic substances, contributing significantly to homeostasis. The other options provided do not accurately describe the main functions of the liver; for instance, insulin production is primarily a function of the pancreas, while regulation of blood pressure and stimulating hunger involve different organs and systems within the body.
