This weekend I went to see the Body Worlds 3 Exhibition in Portland, OR. I have wanted to see this for several years, since first reading about it. A German doctor invented a process called plastination where plastic is injected into bodies to preserve them. The human bodies are donated. It's an alternative to organ donation, as the entire body can be used for exhibits or teaching materials.
Some of the human bodies have been posed in various positions. Some are just arteries and blood vessels - there is plastic injected throughout the bloodstream and everything else is dissolved. This results in a very intricate demonstration of blood flow throughout our various organs. There is also a human nervous system with everything else removed - very interesting to see. One of the coolest and creepiest exhibits was a man holding his own skin - which had been removed entirely.
You will certainly see the human body differently. There are slices of humans - literally. You can compare a healthy brain slice with a brain with tumor slice, a healthy lung with a smoker's lung (this should REALLY make you want to give up smoking!), you can see what emphysema looks like, and other diseases in the body. Overall that was quite interesting.
Overall this was well worth my time and a trip to Portland. I found the embryos particularly interesting. It's just shocking to see how perfectly formed fingers exist just a few weeks into pregnancy. Seeing actual embryos in various stages of development was fascinating.
Personally I didn't like the extreme poses of some of the people, and found the other aspects of the exhibit a lot more interesting. There was a rather grotesque film at the end showing dissection which I sure could have lived without also.
