Protection- the skeleton provides the protection for the vital organs in the body. For example, the rib cage protects the heart and lungs. Another example would be the cranium; it protects the one of the most import vital organs in the body, the brain.
Movement- the skeleton enables movement. It provides a large surface area for muscle attachment. When skeletal muscles contract, they pull on bones at a joint to produce movement.
Produce Blood Cells- the skeleton enables red and white blood cells to be produced in the marrow cavities of larger bones of the body. Red blood cells make haemoglobin and transport oxygen and carbon dioxide around the body. White blood cells help protect the body against infections. Bones such as the femur and the pelvic girdle produce blood cells.
