The hydroxyapatite makes bone solid and makes it able to find charge while the collagen fibers give it its flexibility. In an older person, the amount of collagen fibers decreases, deviation the mineral which makes them less flexible and fragile. Other components change bone from aging conduct osteoblasts and osteoclasts. Osteoblasts are the cells that are amenable for...If you fate to get a full essay, order it on our website: Orderessay
