Answer:
Nervous System
Skeletal System
Muscular System.
The three systems that cause your body to move are nervous system, skeletal system, and the muscular system. The nervous system sends electric signals to different parts of your body, causing them to move. The skeletal system helps your blood move through your body, which makes your heart pump. This helps you recive oxygen. Finnaly, the muscular system keeps your heart beating. Those are the three systems that work together so you can continue to move!
Hope this helps! Have a great day.
