Chewing

From Simple English Wikipedia, the free encyclopedia
A monkey chewing plant matter - masticating - so it is easier to digest

Chewing, or mastication, is the first part of the digestive system. It is when the teeth chew the food and the tongue mixes it with saliva to make it mushy in the mouth. A group of animals, called the ruminants, masticate more than once. Most cattle are in this group.
