rosewhite, it actually doesn't work in the way you describe. DH and I have donated our bodies for medical research. When we die, the whole body is taken to the nearest University that deals with medical research, (likely to be St Andrews for us). Because the University needs the whole body, it's been necessary for us to come off the Donor Register, unfortunately. However, hopefully it'll be a case of swings and roundabouts, and the knowledge gained from 'chopping up our bodies', as you so quaintly describe it, will save as many lives as donating our organs.
