The liver is responsible for many important functions in the body, one of which is the processing of nutrients from food after it is digested. It plays a critical role in metabolism by converting excess carbohydrates into glycogen for storage, and it helps in the regulation of blood sugar levels. Additionally, the liver is involved in the detoxification of harmful substances and the breakdown of fats.

Moreover, the liver produces bile, which is essential for the digestion and absorption of fats in the small intestine.
