how does tongue help us

Tongue Twister
Has anyone ever told you that the tongue is a muscle? Well, that's only partly true: The tongue is really made up of many groups of muscles. These muscles run in different directions to carry out all the tongue's jobs.
The front part of the tongue is very flexible and can move around a lot, working with the teeth to create different types of words. This part also helps you eat by helping to move food around your mouth while you chew. Your tongue pushes the food to your back teeth so the teeth can grind it up.
The muscles in the back of your tongue help you make certain sounds, like the letters "k" and hard "g" (like in the word "go"). Try saying these letters slowly, and you'll feel how the back of your tongue moves against the top of your mouth to create the sounds.
The back of your tongue is important for eating as well. Once the food is all ground up and mixed with saliva (say: suh-LYE-vuh), or spit, the back muscles start to work. They move and push a small bit of food along with saliva into your esophagus (say: ih-SAH-fuh-gus), which is a food pipe that leads from your throat to your stomach.
Tongue Held Down Tight
Have you ever wondered what keeps you from swallowing your tongue? Look in the mirror at what's under your tongue and you'll see your frenulum (say: FREN-yuh-lum). This is a membrane (a thin layer of tissue) that connects your tongue to the bottom of your mouth. In fact, the whole base of your tongue is firmly anchored to the bottom of your mouth, so you could never swallow your tongue even if you tried!
Tasty Tidbits
Don't put that mirror away yet! Look at your tongue again, but this time look closely at the top of it. Notice how it's rough and bumpy — not like the underside, which is very smooth. That's because the top of your tongue is covered with a layer of bumps called papillae (say: puh-PILL-ee).
Papillae help grip food and move it around while you chew. And they contain your taste buds, so you can taste everything from apples to zucchini! People are born with about 10,000 taste buds. But as a person ages, some of his or her taste buds die. (An old person may only have 5,000 taste buds!) That's why some foods may taste stronger to you than they do to an adult. Taste buds can detect sweet, sour, bitter, and salty flavors.
Traveling Tastes
So how do you know how something tastes? Each taste bud is made up of taste cells, which have sensitive, microscopic hairs called microvilli (say: mye-kro-VILL-eye). Those tiny hairs send messages to the brain, which interprets the signals and identifies the taste for you.
Identifying tastes is your brain's way of telling you about what's going into your mouth, and in some cases, keeping you safe. Have you ever taken a drink of milk that tasted funny? When the milk hit the taste buds, they sent nerve impulses to your brain: "Milk coming in — and it tastes funny!" Once your brain unscrambled the nerve impulses, it recognized the taste as a dangerous one, and you knew not to drink the milk.
Some things can make your taste bud receptors less sensitive, like cold foods or drinks. An ice pop made from your favorite juice won't taste as sweet as plain juice. If you suck on an ice cube before you eat a food you don't like, you won't notice the bad taste.
Hope it helped..
