Do you know anything about bones? Bones are rigid body tissues which are comprised of collagen and calcium phosphate. The hard, outer layer makes up around 80 percent of adult bone mass. Bone tissues make up the individual bones of the skeletons of vertebrates. The cells in bones are fixed in a plentiful hard intercellular material. Try this quiz and you will see how much you know about bones.
