What role the Muscular system plays in the
body
Muscles move your whole body! Without muscles you couldn't open your mouth, speak, walk, talk, or move your food through your digestive system. There would be no smiling, eating, breathing. You wouldn’t be able to move anything inside or
outside you. Your muscles do not push, they pull. Muscles often work in pairs so that
they can pull in different directions. Some muscles are called "voluntary"
which means that they only work when you specifically tell them to. If you want to clap your hands, type on a computer, or swing a bat, you use your voluntary movements. Others like the muscular contracting of your heart, the movement of
your diaphragm so that you can breathe, or blinking your eyes are automatic.
They're called in "voluntary" movements. They move by using signals from your nerves, and, in some cases, your brain, as
well.
