- movement
- protein
- make blood cells
- stores minerals and fats.

BONES ARE ALIVE!
- They are living which allows for growth and repair.
- They are strong and lightweight so we are not too heavy.
- Along each bones there are nerves to communicate with other systems.
- Contain an outer membrane called the Periosteum.

Spongy bones: makes bones lighter.
Marrow: RED at ends makes RED blood cells.
