What is Occurs through chewing (mastication) and?

Chewing is how we break food into tiny pieces so our body can use it easily.

When you bite into an apple or a sandwich, your teeth are doing something called mastication, that's just a fancy word for chewing! Your mouth has strong muscles and hard teeth that work together to crush and mix the food.

Imagine you're eating a big, tough piece of bread. If you don't chew it, it’s like trying to swallow a whole shoe, your stomach would have a hard time dealing with it!

But when you chew, your teeth grind the bread into smaller pieces. This makes it easier for your body to turn it into energy and nutrients.

While you’re chewing, something else happens: your mouth makes saliva, that's the wet stuff that helps food slide down your throat. Saliva also has special helpers called enzymes that start breaking down the food even before it reaches your stomach.

So next time you take a bite, remember, you're not just eating; you're doing a little science in your mouth!
