The skeletal system is important because it serves as a support, protection, for movement, storage of minerals and blood cell production.


  1. Support . Rigid, strong bone is well suited for bearing weight
    and is the major supporting tissue of the body.

  2. Protection . Bone is hard and protects the organs it surrounds.

  3. Movement . Skeletal muscles attach to bones by tendons, which are strong bands of connective tissue.

  4. Storage . Some minerals in the blood are taken into bone and
    stored. Should blood levels of these minerals decrease, the
    minerals are released from bone into the blood.

  5. Blood cell production . Many bones contain cavities filled with
    red bone marrow that gives rise to blood cells and platelets
