There's six main functions of the skeletal system
1 - Support
Provides structural support for the entire body.
2 - Protection
Surrounds soft tissue- ex. ribs and sternum protect the heart and lungs, - skull protects the brain.
3 - Movement
Skeletal muscle is attached to bone so it pulls on the bone when it contracts.
4 - Mineral homeostasis

Red bone marrow produces red blood cells, white blood cells and other blood elements.
6 - Storage
Storage of minerals and lipids(fats)---yellow marrow stores fat --(found in long bones).
