Bones

Bones

Walk. Jump. Touch your toes. Bend your knees. Hold your nose. Any way you move, Your bones are helping out.

You have 206 bones in your body. These bones fit together perfectly. Together, they form your skeleton.

Your bones are hidden under your skin. But you can feel them and see their shape.

Your bones start out small, just the way you do. As your bones grow, You grow, too. The smallest bones are inside your ears. The biggest bones are in your legs.

Some of your bones act as armor. A flat bone in the middle of your chest Protects your heart. Your ribs are a bony cage for your lungs and other squishy parts.
