Its matrix is mostly made up of a composite material incorporating the inorganic mineral calcium phosphate in the chemical arrangement termed calcium hydroxylapatite (this is the bone mineral that gives bones their rigidity) and collagen, an elastic protein which improves fracture resistance.

Bones in our body are living tissue. They have their own blood vessels and are made of living cells, which help them to grow and to repair themselves. As well, proteins, minerals and vitamins make up the bone.

Are lungs made up of cells?

The lungs are composed of various specialized cells and tissues -- not just simple tubes or pipes. Lining them are epithelial cells with specialized hairs, or cilia, which help trap particles and prevent infection from reaching the lungs. They also help push foreign and waste matter out of the lungs when necessary.
