The Skeletal System

By: Sam Gentile and Morgan McGurn

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.
