The bile duct is a tube-like structure which carries a digestive juice called bile from the liver and then joins another duct, called the pancreatic duct, that carries pancreatic juice and forms the ampulla of Vater. The contents of both ducts (bile and pancreatic juice) are now discharged into the first part of the intestine called the duodenum through the ampulla of vater.

The pancreatic juice contains enzymes which play a significant role in the digestion of food. The enzymes in the pancreatic juice are responsible for the partial or complete breakdown of carbohydrates, proteins and fat.

One of such enzymes called the pancreatic amylase completes the digestion of carbohydrates. Another enzyme contained in pancreatic juice called lipase is responsible for the breakdown of fat. Two other enzymes contained in pancreatic juice are referred to as trypsin and chymotrypsin. They complete the digestion of proteins.
