Blood tongue

Okay kiddo, so first let's talk about blood. Blood is a very important part of our body. It travels all around us in tubes called blood vessels and helps deliver food and oxygen to our organs and muscles. It also takes away waste that we don't need.

Now, let's move on to the tongue. The tongue is this pink and squishy thing inside our mouth that helps us taste and swallow our food.

When we put these two things together, we get something called a blood tongue. When someone says they have a blood tongue, it means that they might have accidentally bitten their tongue or their tongue might have gotten cut somehow. When this happens, they might bleed a little and their tongue might turn red or even purple in color.

It's important to be careful not to bite your tongue or mouth when eating or playing, but if you do accidentally hurt your tongue and it turns red, just remember that it's a blood tongue and it will heal with time.
