The skeletal System !

The Skeleton is the name given to the collection of bones that holds the rest of our body up. Our skeleton is very important to us. It does three major jobs.

It protects our vital organs such as the brain, the heart and the lungs.

It gives us the shape that we have. Without our skeleton, we would just be a blob of blood and tissue on the floor.

It allows us to move. Because our muscles are attached to our bones, when our muscles move, they move the bones, and we move.
When you were born, your skeleton had around 350 bones. By the time you become an adult, you will only have around 206 bones. This is because, as you grow, some of the bones join together to form one bone.

 

Our bones don't simply work on their own. The bones join together to formjoints. The end of each bone is covered by a tough, smooth shiny substance called cartilage. The cartilage-coated bone-ends are kept apart by a thin film of slippery fluid that works like oil in a car. All of this is so your bones won't scratch and bump against each other when you move. Our bones are held together by strong stretchy bands called ligaments.

You're walking home from school on a windy November day when - whoosh! - a breezy blast smacks you in the face. As your teeth start to chatter and you pull your jacket closed, you notice your eyes are tearing up. You're not sad, so what's going on? The answer is that your eyes are watering. But why?

Tell Me About  tears
First, let's talk about tears. When your eyes water, they're making tears, just like when you cry. Those tears help protect your eyes by keeping them moist and washing out dust and other foreign stuff that gets in there. The tears from watering eyes might only fill your eyes or they might trickle down your face.

The tears come out of tear glands, or lacrimal (say: lak-rum-ul) glands, found way up under your upper eyelids. When your eyes water, the tear liquid washes down from the glands and over your eyes.

Some of the tears drain out of your eyes through tear ducts, or  lacrimal  ducts, tiny  tubes  that run between your eyes and your nose. Each tear duct is right next to the inside corner of the eye; you can't see them because they are under your skin. The tears drain out through the little hole of the duct in the very inside corner of each eye. (You can see the hole if you gently pull down your lower eyelid a bit.)

If tears are flowing quickly, like when you're crying pretty hard, the ducts can't drain them all, so tears run down your face. And have you ever noticed that your nose sometimes runs when you cry? That's because some of the tears making their exit through the ducts end up coming out of your nose.

Why Are They Watering?
Eyes water for lots of different reasons besides crying. Anything that irritates the eye can bring on tears because the eye tries to wash out whatever's bothering it. So when you get something stuck in there, like dirt or an eyelash, here come the tears!

You can't always see the stuff that gets in your eyes. Have you ever walked into a smoky restaurant? If so, you may have noticed your eyes tearing up as protection against the smoke. Even though the  particles  that make up smoke are too small to see, they can still bug your peepers. Eyes might also water if you're around an onion that's being peeled or chopped. The fumes onions give off actually contain tiny chemicals that can get in your eyes and make them hurt. (Holding the onion under water while peeling it can help.)


Things that can dry out your eyes, like cold air or wind, will make them water, too. To protect the eyes from getting too dry, the tear ducts crank out the tears. Imagine skiing down a hill with dry eyes as all that wind rushed at you. That would really hurt!

People's eyes also tear when they have  allergies, infections like a cold, or pinkeye, known as conjunctivitis (say: con-junk-tih-vie-tis). All of these irritations can inflame the eyes and make them water.

You might not think twice about your watering eyes, but some people do have trouble making tears because they have blocked tear ducts. When that happens, the ducts are not able to release the tears properly. Some people are born with stopped-up ducts. Other people's ducts become blocked from an injury or illness, although this is rarer. In most babies who are born that way, the tear ducts eventually open by themselves, but others might need a small operation in the hospital to clear the ducts.

So now you know what your eyes are up to when they get all wet. Just think of those tears as a super shield for your eyes!
