Enlarged hearts. Fatty livers. Blackened lungs. All on display.

If that sounds frightening, it's because in some ways it is. But it's also inspiring and informative, and that's exactly what curators of the Anchorage Museum's latest exhibition hope.

The traveling exhibition, "Body Worlds Vital," that opens Friday is one of several touring "Body Worlds" exhibits. The Anchorage exhibit, the smallest of seven touring exhibitions, focuses on health. The lungs, heart and livers all fit into the context of informing visitors about making healthy choices.

"It allows us -- without raising a finger -- to say, 'Don't do this, don't do that,' " said Dr. Angelina Whalley, director of the Body Worlds' Institute for Plastination in Germany. "Hopefully they'll make better decisions for the rest of their lives."

The exhibit is not the first of its kind to come to Alaska.
