What do the salivary glands, the pancreas, and the stomach have in common?

The salivary glands, pancreas, and stomach all release digestive enzymes that help break food into smaller molecules. Salivary amylase begins digesting starch, the stomach releases enzymes such as pepsin to digest proteins, and the pancreas releases enzymes that act in the small intestine. Therefore, they all secrete enzymes that break down food.
