MUSCULAR SYSTEM
What helps me move?
What your muscles are
There are many different muscles in your body and all help you move in one way or the other. For example, when you reach for something on a shelf, you're using not only your arm muscles, but also muscles in your back and your legs.
Your muscles are made of muscle tissues and require energy to move even a little. The energy it takes to move your muscles comes from the food you eat and is absorbed in the intestine. These little molecules that move your muscles are called ATPs.

Why is this important for the digestive system?
There are certain muscles that help you digest food once you eat it. Some of your organs are made up of a certain muscle and help in other places too. You use muscles when you chew up the food, swallow, and along the digestive system.
