The Human Skeletal System
The skeleton is a group of bones that has six major functions. The first is to support the body’s weight
and protect the body’s organs. To move around, the skeletal muscles push and pull the bones with
connecting ligaments, and the joints allow for much needed rotation to walk. The development of
red and white blood cells takes place in the marrow of the bones. The skeleton also stores nutrients
like calcium and iron. Lastly, bone cells help determine how much insulin the body produces.
