Many animals have skeletons to support and protect their body and to help it move.

The human skeleton is made of bones which grow as we grow. Your bones come in all shapes and sizes. Some of the largest are in your legs, and the smallest are in your ears.

This video will show you why the skeleton is incredibly important for us humans!

All your bones have specific functions:

1. Protection - Your skull protects your brain, and your ribs protect your heart, lungs and other vital organs.

2. Support - The bones in your legs, back and neck keep you upright.

3. Movement - Your muscles pull on your bones so that you can move. Joints between bones, like your elbows and knees, make this easier.

It is important to eat a healthy diet with enough calcium to help your bones grow properly. We find calcium in dairy products like milk and cheese.
