The Human Skeleton

Science · Organisms & Life Processes · conceptual

Describe the structure and four main functions of the human skeleton: support, protection, movement, and production of blood cells in bone marrow

Sign in to track this

What mastery looks like

  • Lists and explains the four functions of the skeleton with examples
  • Names key bones and identifies which organs they protect (e.g. ribcage protects heart and lungs)
  • Explains what bone marrow is and where blood cells are made

Check your understanding

If The Human Skeleton was asked why we have bones, could they explain that bones do more than just hold us up — describing at least three different things the skeleton does for the body?
