Have you ever wondered why your favourite foods taste so good? Well you can taste everything because of your of your taste buds. Taste buds are little sensitive organs that you find on the top of your tongue, you can find on the top of your tongue, and that allow you to taste foods that are sweet, salty, sour and bitter. But how exactly do your taste buds work?

On your tongue you should see a lot of little bumps. Those are called papillae, and most of them contain taste buds.-Papillae help grip food and move it around when you are chewing. Taste buds have very sensitive microscopic hairs called microvillus. Those tiny hairs send messages to the brain as well as the nerve endings in your taste buds.

The average person has 10,000 taste buds and they're replaced every 2 weeks or so. But as a person gets older, some only have 5,000 working taste buds.
