What if we didn't have bones or what would happen if humans didn't have bones?
You'd be floppy like a beanbag. Could you stand-up?, Forget it. Could you walk?, No way. Without bones you'd be just a puddle of skin and guts on the floor. 

Skeletons are very helpful to humans and animals. A skeleton is a rigid framework without which none of our other body-parts would stay in place. If we didn't have a skeleton under our skin, protecting our organs we would just be a lump of jelly on the ground

Are your bones alive? 

Absolutely. Made mostly of collagen, bone is living growing tissue. Like other cells in your body, the bone cells rely on blood to keep them alive. Blood brings them food, and oxygen and takes away waste. 

How many bones do humans have? 

When you were born you had over 300 bones. As you grew, some of these bones began to fuse together. The result?  An adult has only 206 bones

What's bone marrow? 

Bone marrow makes new red and white blood cells. Who would have thought that bones make blood!?! 


The Skeletal System Interesting Facts

The largest bone, is the pelvis, or hip bone. In fact it is made of six bones joined firmly together. 

The longest bone, is the 'femur', in the thigh. t makes up almost one quarter of the body's total height. 

The smallest bone, is the 'stirrup', deep in the ear. It is hardly larger than a grain of rice. 

The ears and nose do not have bones inside them. Their inner supports are cartilage or 'gristle'.

The human hand has 27 bones; your face has 14! 

Did you know that humans and giraffes have the same number of bones in their necks? Giraffe neck vertebrae are just much, much longer! 

You have over 230 moveable and semi-moveable joints in your body.
