The <u>secretion</u><u> </u>of acids, buffers, enzymes, and water aids in the breakdown of food.
The food moves through the gastrointestinal tract and breaks down into smaller particles for energy, cell repair, and growth.
Digestion begins when eating and chewing food with the help of teeth in the mouth, then it goes down to the small intestine.
While moving through the gastrointestinal tract it mixes with juices, acids, enzymes, and water which disintegrates the large molecules of food into smaller ones and makes it suitable for assimilation and absorption in the body.
