Bone Function and Importance

  • Support and Structure - Bones provide a framework that supports the body and gives it shape.
  • Protection - Bones protect vital organs; for example, the skull protects the brain, and the ribcage shields the heart and lungs.
  • Movement - Bones act as levers that muscles pull on to produce movement.
  • Mineral Storage - Bones store minerals such as calcium and phosphorus, which can be released into the bloodstream as needed.
  • Blood Cell Production - Bones contain bone marrow, which produces red and white blood cells and platelets.
