Muscles

In school we are learning about the body systems. Today I am going to tell you about the muscular system. Your muscles take up 50% of your body weight. Your muscles help your bones move. If you didn't have muscles you could not move. 


The picture is the circulatory system, the digestive system, part of the skeletal system, part of the muscular system, and the respiratory system. I made this poster at school on Surgery Day.
