Mastication (Chewing): Definition Muscles Biology ...

Oct 04, 2019  Mastication Definition. Mastication is the mechanical grinding of food into smaller pieces by teeth; it is essentially a technical word for “chewing”.Mastication breaks down food so that it can go through the esophagus to the stomach.Breaking down food into smaller pieces also increases its surface area so that digestive enzymes can continue to break it down more efficiently.
