What are Skeletons and Bones Made Of?
Skeletons and bones are made of a protein called collagen and a mineral called hydroxyapatite. Collagen gives bones their strength and flexibility, while hydroxyapatite makes them hard and rigid. The combination of these two materials makes bones strong enough to support the body and protect the organs.
Bones are not solid structures. They are actually made up of a honeycomb-like network of small, hard crystals called osteons. Osteons are arranged in a way that makes bones strong and lightweight.
Bones are constantly being remodeled. Old bone is broken down and replaced with new bone. This process ensures that bones stay strong and healthy.
