From Mouth to Rectum - about the Digestive System.

From Mouth to Rectum

With this exhibition, we hope to contribute with new knowledge and understanding of the functions of the organs of the digestive system, and the biological, chemical and mechanical processes involved in digestion.

We also want to provide an overview of what our most important nutrients consist of, how and where they are divided into smaller parts in the system, which factors affect them, and how they travel from the digestive system to other organ systems within our bodies.

Mirjam Mitternacht developed the exhibition “From Mouth to Rectum – A Pedagogical Exploration of the Digestive System” as a degree project on the Master’s programme in Industrial Design, in collaboration with Vattenhallen Science Center and the Department of Food Technology. With the support from Sparbanksstiftelsen Färs och Frosta (Savings Bank Foundation), Accus, Danone, Probi and Tetra Pak, the exhibition was made possible to create and implement.
