Would you be able to stand without bones?

• You would not be able to stand upright, or walk.
  You would just be a puddle of dirty water
  flopping around on the ground.
• Bones also protect the body, such as your skull
  protecting your brain. Your backbone provides a
  structure so you are able to stand upright.
• Even your ribs are protecting your organs such as
  your heart, and lungs.

How do your bones move?

• Your bones need LOTS of help from your muscles.
  Your muscles are attached to your bones, which is
  key for body movement.
• Joint are also important because they provide
  flexible movement between your bones. You neck
  has joints so you are able to turn your head.
  Your shoulder has joints so you are able to move
  your arm 360 degrees.

• Muscles help move your bones. When your muscles
  contract, the bones your muscles attach to act as
  a lever to move various parts of your body.
