Get ready to learn about your skeletal system! Your body has lots of bones! Bones help give your body shape. All your bones together are called your skeleton. When we talk about the way your bones work together it is called your skeletal system. Without your skeleton, you could not stand or even move. Think about what your life would be like if you didn't have a skeleton, or if your bones didn't work together in a system.
