'''Bone''' is living, growing [[tissue]] made mostly of collagen. [[Collagen]] is a protein<ref>[http://folding.stanford.edu/download.html Protein & Folding]</ref> that provides a soft "framework", and [[calcium]] is a mineral that adds strength and hardens the framework. The combination of collagen and calcium makes bone the strongest and most flexible material in a living body. More than 99 percent of the body’s calcium is contained in the bones and [[teeth]]. The remaining 1 percent is found in the [[blood]].
