Well, despite all nagging concerns I had, I went to Body Worlds (BW) on Monday.
Before I comment on the actual display, I wish to address the concerns I had:
1. I found the allegations that BW received human bodies through suspicious means groundless. No concrete evidence was uncovered since the allegations were made. On top of that, BW went out of their way to show the process and consent forms for accepting bodies via donations to science. In short, I was satisfied the donors had given their informed consent.
2. The consent forms include a box to check if the donor consents to his/her organs being sold to educational institutions, with proceeds going to covers the costs of the plastination process, not for profit. I found this to be a reasonable request.
3. The BW display did not show the donors in a demeaning fashion. The poses were mainly for educational purposes, although I would recommend not taking children under 12 to the show (of which there were quite a few, unfortunately).
To sum up, I am satisfied most of my concerns were adequately met and I felt more comfortable viewing most of the displays.
That said, for those who feel comfortable, I fully recommend seeing Body Worlds. The exhibit I went to organised the displays by the different systems of the body which included (not an inclusive list) skeletal, muscular, nervous, circulatory, respiratory, digestive, urination and kidneys, reproductive, etc. The only room I didn't spend a lot of time in was the fetal development room. I took a quick scan, found I wasn't entirely comfortable with viewing it, and waited outside for my wife (who found it very interesting and would recommend all teenage girls see it in order to give them a more complete picture of what goes on during pregnancy).
Also included were banners showing the history of anatomy. One of the most intriguing (IMO) was the viewing theatres from Renaissance times were the rich and poor would mingle amongst each other while viewing autopsies/dissections (I would have thought there would have been a section set aside for the rich and another for the poor).
The displays showed both a "normally functioning" body and how diseases affect the function (there were a lot of smokers who donated their bodies!). The "normal" bodies displayed many impressive features, including (and forgive me for not remembering the proper names) four arteries going from the heart to the brain that connect in a circle at the base of the brain, helping to ensure sufficient blood flow in the event one of the arteries gets blocked.
The main thing I took from this is that a "normally functioning" body gives the strong appearance of an efficiently designed system*. By efficient, I mean that each discrete system (i.e. skeletal, circulatory, etc.) appeared "designed" to provide optimum function of that system given certain constraints and requirements from other discrete systems and/or the larger system (i.e. the human body). Each discrete system works together to provide a larger multi-functional and adaptive system. Take away or significantly change a component of a local system, the larger system can still function, but not at the efficiency of the "normal" body.
All in all, I found Body Worlds to be a fascinating exhibit that treated the donated bodies with dignity and respect while providing an educational aspect that the layman can grasp.
*Efficient System Design is a concept I will be dealing with in more detail in the near future, but feel free to comment on it. I enjoy and appreciate everyone's point of view (thus far).
