    1. Leverage: skeletal system allows movement by co-ordinated action ofmuscles on bones, providing leverage

    2. Attachment of muscles: parts of skeleton (usually flat bones) providesurface for muscles to attach

    3. Protection: skeleton protects vital tissues/organs e.g. skull protects

    brain4. Shape/Support: skeleton gives body shape. Provides framework forsoft tissues (muscles, etc.) & prevent it from collapsing in heap

    5. Blood cells: bones not solid - inside long bones are BONE MARROWwhich produce & replace white (generally in shafts of long bones) &red blood cells (generally at ends of longs bones & some flat bones)
