Deoxyribonuclease and ribonuclease, produced in the pancreas. They are enzymes that break bonds in nucleic acids like DNA and RNA.

Gastrin, which signals the secretion of gastric acid.

Cholecystokinin, which signals the secretion of pancreatic enzymes.

Secretin, which signals secretion of water and bicarbonate from the pancreas.
