There are two kinds of anatomical gifts: body donation for medical research and organ donations for transplants.
In our society, people care about what is done to human bodies, both during life and after death. Donation for Medicine and Research acknowledges that whatever the potential benefits, the human body needs to be treated in a manner commensurate with the public's concerns. For most people, it matters (in life and death) that bodies are treated with respect, and a constructive approach to anatomical donation must acknowledge and act in accordance with this fact. Usually, a body is donated for one of these purposes, but not both.
