People who wish to donate their entire body to medical science should contact the medical school or willed body program of their choice and make arrangements to do so before they die. Medical schools need bodies to teach medical students about anatomy, and research facilities need them to study disease processes so they can devise cures. Since the bodies used for these purposes generally must be complete with all their organs and tissues, organ donation is not an option. Some programs, however, make exceptions. You can inform your family that organ donation is your first choice, but if it is found that you are not medically suitable for organ donation, your family can carry out your wishes for whole body donation.
