The pancreas, liver, and gallbladder are accessory organs of the digestive tract that have many functions, one of which is to produce digestive juices and enzymes that aid in digestion.

Saliva moistens the food and amylase, an enzyme in saliva, begins the process of breaking it down. Food moves through the esophagus and enters the stomach, where digestive enzymes and stomach acid continue breaking it down. The resulting breakdown product, called chyme, contains carbohydrates, small proteins, minerals, fats, vitamins, and water. Chyme exits the stomach and enters the small intestine.
