Some diseases that affect the skeletal system

The resources that helped me with my research on the skeletal systems are:

Who has more bones a baby or an adult?

Babies have more than adults! At birth, you have about 300 bones. As you grow older, small bones join together to make big ones. Adults end up with about 206 bones.

What is a bone made of?

Bone is made mostly of collagen, a protein that is woven into a flexible framework. Bone also contains calcium phosphate and calcium carbonate, minerals that add strength and harden the framework. The combination of calcium and collagen gives the bone its strength and flexibility.

How do bones break and heal?

Bones are tough and usually don't break even when we have some pretty bad falls. Bones will bend a little, but if you fall the wrong way, you can break a bone. Doctors call a broken bone a fracture. There are many different types of fractures.

Luckily, bones are made of living cells. When a bone is broken your bone will produce lots of new cells to rebuild the bone. These cells cover both ends of the broken part of the bone and close up the break.

Skeletal system!

Skeletal system description.

How the organ works

1st the skeleton protects our organs suck as the brain,heart,

& the lungs.

Our skeleton is important to us,

Well the skeletal systems does not work, but it protects, helps protect your internal organs and fragile body tissues. The brain, eyes, heart, lungs and spinal cord are all protected by your skeleton The skeleton works very closely with the muscular system to help you move.

2nd it gives us the shape that we have, without that we would be a blob of blood & tissue on the floor.

3th it allows us to move to places, cuz our muscles are attached to our bones, so when our muscles move , our bones move, so we move.
