There use to be an attraction that had to do with traveling through the body. Stomach acids or something like that. A "show" I believe. Is that still in Epcot?
They also had a show called Cranium Command that was in that building. Now it is used as a hub. Flower and Garden, Food and Wine had large displays in it.
Nope. All of that was in the "Wonders of Life" pavilion which is now closed up. The building is still used for special events but the attractions are no more.
