Exhibition’s topics

The purpose of the exhibition is to demonstrate the amazing functions of those parts of our bodies that are often forgotten. Some of the exhibition’s topics, such as intestinal bacteria, are currently the subject of extensive research. The latest research information has been utilised in planning this exhibition, and the contents will be further updated as new research results become available.

This exhibition is opened as part of Heureka’s main exhibition and has been designed in co-operation with the Finnish Medical Society Duodecim in honour of its 130th jubilee year in 2011.
