We had the opportunity last night, after arriving in Las Vegas, to take some time out and check out an exhibit that intrigued us entitled "Bodies...The Exhibition".  Wow!  The exhibit takes you through the entire body, every system, each part.  What's most fascinating is you're not looking at diagrams or models but actual people preserved by by some polymers.

Each room in the exhibit is themed to an aspect of the human body (i.e. skeletal structure, circulatory system, respiratory system, reproductive system, digestive system, etc).  There are 'view boxes' with each piece of the body perfectly preserved (some even demonstrated characteristics of disease such as Cirrhosis of the Liver) and one or two almost complete bodies in dramatic poses that further illustrate that particular aspect of the body.

One room that greatly intrigued me was dedicated to the circulatory system.  Each view box in the room had the blood vessels of each of the major organs of the human body (and one complete body as well!) - but just the blood vessels.  Turns out that to accomplish this the organ's vessels were filled with the polymer solution, then the polymer was allowed to harden, and then all organic material was dissolved away leaving only the structure of the veins.  In a word: awesome!  Especially the complete body.  Each exhibit represented only about 60% of the veins in the body because the capillaries are too small for the polymer to enter.

If you get a chance, I would highly recommend taking the time to see it and experience it.  You'll not regret it.

On a side note, I'm rather proud of myself for my restraint.  That is, not once did I break out and say that most memorable line from The Sixth Sense. :)
