Have you ever wondered,
How our bodies work inside?
We move, we breathe, we eat,
we think, and somehow stay alive!
We have 12 major systems.
Only 7 we’re gonna talk about:
Skeletal, muscular
Circulatory, nervous,
Digestive , excretory,
and respiratory system.
We use our skeletal and muscular systems,
to move.
Our heart in the circulatory ,
never get tired.
The brain in the nervous ,
the boss that control our body.
The digestive system,
break down the food we eat.
The excretory remove wastes from the blood.
The respiratory allows us to breath air.
