Essay

       Introduction
Have you ever wondered how you taste things like ice-cream or chocolate or why when you hold your nose you can’t smell?  Well, I’m here to tell you why.  

                  Paragraph 1: Taste
At the top of your tongue there are tiny little bumps called Papillae. Inside the Papillae are your tastes buds. Taste buds have very sensitive microscopic hairs called microvilli. Those tiny hairs send messages to the brain, about how something tastes, so you know if it's sweet, sour, bitter, or salty

                                   Taste 2
You have about 10,000 taste buds on your tongue. Younger children are so picky because they have so many taste buds. Taste buds can disappear if you drink hot drinks, but the they heal after a while. The taste buds help you to taste 5 main things which are sweet, sour, salty, bitter and umami (savoury). Kids taste buds are more sensitive to sweet things, that is why chocolate can be more liked than broccoli. Saliva also helps you taste, it activates the taste buds so you can taste. If you have a dry tongue then you can’t taste anything.  

                     
                 

Paragraph 2: Smell
Did you know that 90% of your taste is smell is taste? That means the if you smelt something like a piece of cake it would taste almost exactly how it will taste when you eat it. Olfactory receptors are tiny hairs in your nose. They are in the uppermost part of your nose and have special cells that help you smell and taste. Olfactory receptors send messages to your brain, so your brain can tell you what you’re tasting. If you have a blocked nose, food will lose its flavour.


                   Paragraph 3 : Speech
The Tongue is also vital for speech. When you speak you your vocal cords produce a raw sound. The tongue helps the raw sound of the vocal cords so when you talk people can understand what you're saying. It takes babies and kids quite a while to be able to form the right sounds. Letters like G and K come from the back of the tongue.  The position of the tongue also helps speech. It helps say the vowels in words like “father”, “had” and many others.  




                     
 Conclusion
Tongues are are very important. They help taste, talk and swallow food. So without your tongue you wouldn’t be able to talk or taste.
