The Skeletal System
By Brandi Waters |
|
1 No bones about it, the skeletal system is tough! One of the jobs of the skeletal system is to act as armor for your body's most important organs and tissues. That is the job of your skull, ribs, and backbone. These bones protect the softer tissue underneath them from being damaged. The skull surrounds the brain and keeps it safe when your head hits the ground. Your ribs surround your heart and lungs and keep them from being hurt when a ball hits you in the chest. Your backbone surrounds your spinal cord, a bundle of nerves that connects your brain to the rest of your body.
