This paper proposes one possible avenue for defining a framework to address body parts. I begin with the presumption that given the increasing use of body parts outside of our bodies, either after death or during life, society requires a framework with institutions and rules to govern our body parts. Yet there is no settled framework. Much of the controversy over differing approaches stems from whether people should be able to sell body parts. Thus, each potential framework implicitly addresses the question of monetary value. While multiple possibilities exist, the predominant models are (1) property, most often meaning ownership that permits monetary compensation; (2) stewardship, implying altruism and no monetary compensation to the donor; and (3) a compromise solution involving regulatory bodies, which could assign monetary value under certain circumstances.
