- Shape - gives shape to the body and makes you tall or short.
- Support - holds your vital organs in place when playing sport. The vertebral column holds the body upright.
- Movement - muscle are attached to bones, which are jointed. When the muscles contract the bones move.
- Blood production - red blood cells (to carry oxygen) and white blood cells (to protect against infection) are produced in the bone marrow of some bones.
