Study Notes
Bone Composition
- Bones are composed of 25% water, 25% organic matter, and 50% inorganic matter.
- The major organic component is collagen, a protein found abundantly in the body.
- Collagen provides bones with flexibility and some strength.
- Inorganic components, primarily calcium salts, make bone hard and strong.
- Calcium salts give bones the ability to withstand pressure.
- An adult can carry up to 7 kg of calcium.
- Organic components allow the bone to flex and move.
