Your tongue is wet because it has a special job of helping you taste and eat your food!

Imagine your tongue is like a super helper in your mouth. It has lots of tiny little parts called taste buds that can taste different flavors like sweet, sour, salty, and more. These taste buds need to be a little wet to work well.

When you eat, your tongue moves around and helps mix the food with your saliva. Saliva is like the watery stuff in your mouth, and it helps break down your food so you can swallow it easily. It's a bit like your tongue's way of helping your tummy by making the food all mushy.

So, your tongue stays wet to help you taste your food and help it get ready to go down into your tummy. It's like your tongue's way of saying, "I'm here to make eating yummy and easy for you!"
