What is the purpose of the liver in the digestive system? I know that it produces bile, but what other functions does the liver have in the digestive system? Where does bile go?

Liver function is when it processes a meal, it removes sugar from the blood and stores it in the form of glycogen. When a person’s blood sugar decreases, it converts that stored glycogen to glucose, adding the proper amount of instant energy into the bloodstream for the cells to use. Once the glycogen store is used, the liver will create glucose from other carbohydrates and a form of protein. It breaks down fats that are eaten, converting excess carbohydrates and protein into forms that are stored for later use.

Bile is a complex fluid containing water, electrolytes and a battery of organic molecules including bile acids, cholesterol, phospholipids and bilirubin that flows through the biliary tract into the small intestine. Secretion into bile is a major route for eliminating cholesterol. Free cholesterol is virtually insoluble in aqueous solutions, but in bile, it is made soluble by bile acids and lipids like lecithin.
