What you'll learn

Key ideas in How Your Body Works

  • Bones are constantly broken down and replaced by new cells
  • Ball-and-socket shapes allow movement in all directions
  • Bone tissue requires a blood supply to stay healthy
  • Hinge joints limit movement to a single plane
  • Physical stress or exercise signals bones to become denser
  • Fixed joints provide stability without motion
  • Bones are living, changing tissues rather than static objects
  • Joint shapes dictate the specific movement of limbs
  • The ribs shield the heart and lungs from impact
  • Bone marrow is the primary site of blood cell production
  • The gaps between ribs allow the chest to expand for breathing
  • Bones are hollow to house this 'factory' without being too heavy
  • The skull is a solid dome because the brain does not need to expand like the lungs
  • Blood cells must be constantly replenished by the skeleton
  • The skeleton's role in protecting vital organs
  • The role of bone marrow in blood production
