Yes, There Are Two of Them
Las Vegas has not one but two body exhibits built from real, preserved human bodies: Bodies The Exhibition at the Luxor and REAL BODIES at Horseshoe. Both work like a body museum you walk through at your own pace, using genuine specimens preserved so you can see how the human body actually works. The decision comes down to which one fits your trip, and here is how they compare.

Bodies The Exhibition at the Luxor
Bodies The Exhibition at the Luxor is the longer-running of the two -- a full walk through the human body using real specimens preserved by a process called polymer preservation, in which tissue and water are replaced with silicone rubber to halt decay and lock every detail in place. The result lets you study the muscular, skeletal, circulatory, and nervous systems up close, carefully dissected to show exactly how everything connects. It is genuinely educational and, for most visitors, far more fascinating than macabre.
This is the pick if you want the established, classic version, and it is easy to fold into a day at the Luxor alongside the hotel's other exhibitions.

REAL BODIES at Horseshoe
REAL BODIES at Horseshoe covers similar ground with a slightly different personality -- a tour through whole preserved bodies and individual organs, organized by the body's systems and threaded with genuinely fun facts and a lighter, more conversational tone. Its central-Strip location at Horseshoe makes it the more convenient stop if you are staying mid-Strip. Same core idea, a bit more playfully delivered.
Choose it if you want the same eye-opening anatomy in a marginally more upbeat package, or if Horseshoe is simply the closer walk.

The Practical Truth
Here is the honest version: these two body exhibits are more similar than the marketing suggests, and you will not go wrong with either. Bodies at the Luxor is the classic, longer-running option with a strong focus on the preservation science. REAL BODIES at Horseshoe is the slightly more playful take, with a central-Strip address. Choose by which hotel is closer to where you are staying -- both deliver the same genuinely surprising look beneath the skin. Check the booking section below for hours and tickets.
Both exhibits pair easily with something else nearby. At Horseshoe, Paranormal puts a FISM-champion mind reader in an afternoon slot inside the same resort, so REAL BODIES and a show fit before dinner.
