2. 1. Support
○ Provides the structural support needed for the entire body.
2. Protection
○ Surrounds the soft tissues
■ example: The skull protects the brain and the ribs and sternum protect
heart & lungs.
3. Movement
○ Skeletal muscles attached to bone pull the bone as muscle contracts.
4. Mineral Homeostasis
○ Bones store calcium & phosphorus that are able to then be released into the
bloodstream as needed.
5. Blood Cell Production
○ Both red & white blood cells, along with other blood elements are produced
in the red bone marrow.
6. Storage
○ Bones store minerals & lipids. Yellow marrow, found in long bones, stores
fat.
