Describe the four structural roles of the skeletal system.<br> The Human SKELETAL SYSTEM
makkiz [27]

Answer:

1. Support

2. Protection

3. Movement

4. Supply & Storage

Explanation:

1. Support :  It provides a framework to support the organs and tissues of the body.  

2. Protection:  It protects our internal organs.  The skull protects the brain; the thorax (sternum, ribs and spine) protects the heart, lungs and other viscera (organs within the thorax).

3. Movement:  It provides a framework for muscles to attach.  Then when the muscles contract they pull on the bones of the skeleton, which act like levers to create movement.

4. Supply & Storage:  The bones that make up the skeleton are a source of both red blood cells (which transport oxygen) and white blood cells (which fight infection), which are formed within the bone marrow.
