The bones that form the skeleton are made of an organic matrix—collagen, and inorganic crystals of calcium and phosphate, plus water. The bones are made to support the body's weight as well as quite larger stresses. Collagen is responsible for bone's great elasticity and the inorganic crystals for their resistance to tensile and compressive forces. The elastic properties of bone are compared with those of steel-reinforced concrete.
