Pancreatic juice is an alkaline secretion of the pancreas, a large gland which sits somewhat behind the stomach from where it empties its secretions into the upper part of the intestine called the duodenum. This is regarded as the exocrine function of the pancreas. In addition to pancreatic juice, the pancreas secrets hormones, mainly insulin and glucagon, a role which is regarded as the endocrine function of the pancreas.

The pancreas plays a very significant role in food digestion because the enzymes contained in the pancreatic juice partially or completely break down the carbohydrates, proteins and fat we eat.

An enzyme called the pancreatic amylase is the enzyme contained in pancreatic juice which is responsible for completing the digestion of carbohydrates. Trypsin and chymotrypsin are the enzymes contained in pancreatic juice which complete the digestion of proteins and another enzyme called lipase is the enzyme responsible for the breakdown of fat.

A digestive juice called bile originates from the liver and it is transported in the common bile duct which joins the pancreatic duct carrying pancreatic juice  to form the ampulla of vater. It is through the ampulla of vater that both contents are discharged into the first part of the intestine called the duodenum.
