What does your skeleton do?

The skeleton

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

The human skeleton is made of bones and grows as we grow.

Our skull protects our brain and our ribs protect our heart and lungs.

The skeleton bends at joints such as knees and ankles. Joints are where two or more bones join together
