Why is the liver important in digestion

The liver has multiple functions, but its main function within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat. In addition, the liver is the body's chemical "factory."

the liver's main function is to filter out harmful products from the foods and drinks we consume. most notably, if we didn't have, we wouldnt be able to drink beer.
