Chewing or mastication is the process by which food is crushed and grounded by teeth. It is the first step of digestion, and it increases the surface area of foods to allow a more efficient breakdown by enzymes... After chewing the food ( now called a bolus) is swallowed. Hope this helps.
When you first put a piece of food in your mouth, it is first grinded by your teeth, then saliva comes in to help you break down your food, the more you chew the more digestive enzymes occur, these enzymes are extremely important, they help your body take in nutrients from what you eat. This is why it's important to chew your food thoroughly before you swallow,
