What is plastination?

Plastination is a process used to preserve bodies or body parts by removing the water and fat in the body and replacing it with special plastics. Plastination is used to produce anatomical specimens that do not smell or decay. The plastinated parts retain most of their original properties, and can be touched and studied. It is possible to plastinate something as small as a piece of tissue, or as large as an entire human body. Plastination is useful in preserving bodies that have been donated to science by converting them to models and teaching tools.
