Skeleton and Circulation 1

Humans, and some other animals called vertebrates, have a bony skeleton inside their bodies, which grows as they grow.

The skeleton:

- protects the important organs - brain, heart, lungs

- supports and gives our bodies shape

- helps with movement because the muscles are attached to the bones. 

Food and oxygen are pumped through our circulatory system by the heart.
