- The Digestive Process. The digestive tract -- also called the gastrointestinal tract or alimentary canal -- provides the pathway through which foods move through the body. During this process, foods are broken down into their component nutrients to be available for absorption. Digestion actually begins in the mouth, as the enzymes in saliva begin to break down carbohydrate (starch). As food is chewed, it becomes lubricated, warmer, and easier to swallow and digest.

What is Digestion? - Definition & Process So, digestion begins in the mouth when you chew and ends in the large intestine 18 to 20 hours later. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. Think of a can of tomato soup. When you open the can, it is a thick red blob.

- Mechanical and chemical digestion begin in the mouth with the chewing of food and the release of saliva, which starts carbohydrate digestion. The epiglottis covers the trachea so the bolus (ball of chewed food) does not go down into the trachea or lungs, but rather into the esophagus.

Where does digestion occur? Digestion occurs in the gastrointestinal tract—the 20 to 30 foot long tube extending from your mouth to your anus. Whatever you eat flows through this system, but until it is absorbed through the intestinal tract, the nutrients in food are physically outside of your body.

The Anatomy of Digestion Digestion takes place whenever and wherever food comes into contact with digestive enzymes. Salivary glands at the base of the tongue secrete enzymes that begin the digestion of carbohydrates. Enzymes secreted by the lining of the stomach are involved in protein, fat and milk digestion.

What Organs Make Up the Digestive System? Organs of the Gastrointestinal Tract. Oral cavity. This is your mouth, and while it's not technically an organ, it's important because digestion begins in your mouth when you bite and chew your food, thus mixing it with saliva. The saliva (or spit) moistens food so that it's easier to swallow. It also contains a little bit of salivary amylase, a digestive enzyme that breaks down carbohydrates.
