937 - What are bones made of, and how do they support the body?

Bones are made of a special combination of materials. They have:

1. Collagen, a protein that gives bones their strength and flexibility (like a strong rope).
2. Calcium and phosphorus, minerals that make bones hard and strong (like concrete).
3. Bone cells, tiny living cells that help bones grow and repair themselves.

These materials work together to make bones strong, flexible, and lightweight. Bones support the body by:

1. Protecting internal organs like the brain, heart, and lungs with a hard outer layer.
2. Providing a framework for muscles to attach and move the body.
3. Supporting the body's weight and helping us stand, sit, and move around.
4. Storing calcium and other minerals that the body needs to function properly.

Think of bones like a strong, flexible, and lightweight framework that helps us move and live our daily lives!
