Digestive enzymes are secreted by different exocrine glands including salivary glands, gastric glands, secretory cells in the pancreas, and secretory glands in the ...
The pancreas is also the main source of enzymes for the digestion of fats and proteins. Some of these are released in response to the production of cholecystokinin in the duodenum. (The enzymes that digest polysaccharides, by contrast, are primarily produced by the walls of the intestines.)
Every day, seven liters of fluid are secreted by the digestive system. This fluid is composed of four primary components: ions, digestive enzymes, mucus, and bile.

Saliva, a liquid secreted by the salivary ...
