What are the functions of liver and pancreas in the human digestive system ?

Liver secretes bile, which helps in making the acidic food alkaline. Also, it digests fats. Pancreas secretes the digestive juice containing three enzymes, i.e. amylase, trypsin and lipase. Amylase digests starch; trypsin digests proteins and lipase digests fats.
