When bodies are plastinated, a technique pioneered by Gunter von Hagens in 1977, the body is first treated with formaldehyde, similar to an open-casket funeral, but at a higher concentration.The veins and arteries are injected with red and blue plastics.
The body is then dissected in any way required for the planned exhibit or sale piece.
After dissection, the specimen is placed in an acetone bath its temperature is lowered to below the freezing point of water, but above the freezing point of acetone. When the water in the cells expands due to freezing, it’s drawn out of the cells, and it’s replaced by acetone.
When all of the tissues are impregnated with acetone, the body is placed in a bath of polymer or plastic resin, and placed into a vacuum. Because acetone has an already-low boiling point, putting it into a vacuum causes it to boil at room-temperature, while still in the cells. The vaporization of acetone in the tissues leads to a negative pressure, which draws the polymer into the empty spaces.
After the body is fully infused with the polymer, it’s posed as it will be in its final form and cured (with gas, UV light, or heat) according to what it’s infused with, and hardened in place.
To improve heart health, a diet with more fruits and vegetables and without high-fat foods is required. Keeping one’s body mass index less than 25 is also important. Getting 30 minutes of exercise every day conditions the heart and body. Exercise also keeps the extra pounds off and lowers blood pressure. Kicking a cigarette smoking habit - or never starting - will also help foster good heart health.
Small changes in daily routines can also make an impact: take the stairs instead of the elevator, go for a 30-minute walk after work instead of watching a TV show, substitute fruit for potato chips as afternoon snacks.

Plastinates and plastinate sheets have been a staple for medical colleges and museums for some time. Using finely tuned machinery to slice perfect deli-thin pieces of entire bodies, these slices are then perfectly preserved in plastic resin, displaying their anatomy beautifully forever. Many science museums across the country are proud owners of human plastinate sheets; I however have to make due with a rat.
One medical laboratory that makes plastinate specimens for research purposes has a shop on etsy and has taken to selling a few of the specimens in addition to high quality prints of them. Naturally, once I had the $80 to buy the little slice of rat I had to have it. This is a cross section of a labrat head. You can clearly see the skull and spine and organs and even some of his floofy little hairs and even a whisker ISN’T THAT CUTE?!
This photo was taken by holding the specimen up against the sky on a cloudy day and very carefully snapping the photo with my free hand.
Esta técnica fue desarrollada por Gunther von Hagens en 1977. Consiste en preservar cuerpos o partes de cuerpos reemplazando su grasa y agua con ciertos plásticos. El resultado son cadáveres plastificados que no se pudren ni huelen e incluso mantienen las propiedades de la muestra original.
Todas las fotos que ven aquí son humanos que pasaron por ese proceso luego de donar sus cuerpos.
Somos un río interminable de carne y sangre. En nosotros fluyen millones de muertos.
Body Worlds (German title: Körperwelten) is a traveling exhibition of preserved human bodies and body parts that are prepared using a technique called plastination to reveal inner anatomical structures. The exhibition’s developer and promoter is German anatomist Gunther von Hagens, who invented the plastination technique in the late 1970s at the University of Heidelberg
