THE LOCOMOTOR SYSTEM
The locomotor system makes our
body move.
It’s made up of bones, joints and muscles.
We have 600 muscles. They are flexible
and elastic.
We have 206 bones. They are rigid
and hard.
At the joints tendons attach muscles to the bones.
Our circulatory system transports nutrients and oxygen.
It is made up of heart, blood and the blood vessels.
The blood is a red liquid. It travels in
thin tubes called blood vessels.
The
heart is a muscle. It works day and night.
