Taste Taste is your tongue. If we didn't have a tongue then we wouldn't be able to taste nice foods and bad foods. The way that the tongue works is the taste buds works together to tell the brain if it is bad or good. we have over 10,000 taste buds in our mouth and every single one of them gets replaced every two weeks. when you look in the mirror you can't really see them but they are one of the most important things in our body On our tongue it is split up into three different sections sweet at the very tip of the tongue and then the salty and sour are on the sides. On the back side of the tongue there is the bitter . If we never had taste we wouldn't be able to experience what nice foods would taste like.
