Skeletal System
Fact: The strongest bone in your body is the jaw-bone!
Functions
Although you never see your bones, and hopefully never will, they are still very much alive and serve as a very important part of keeping your body together, pun intended. The functions that the skeletal system serves in your body are:
- Structural support
- Protection of vital organs from physical force
- Production of red blood cells
- Links with ligaments and joints to provide efficient movements
- Storage of salts and minerals
