How does cryogenics work?

Question

From my understanding, cryogenics is where you freeze a living thing in extremely low temperatures and it stays alive. Is this true? If so, how could it be possible? Wouldn't it die of hypothermia or frostbite? What about eating, drinking, and breathing? Wouldn't your blood freeze?

Thanks

Answer 1

It is a term used to freeze an organism so that it could be later revived. At this point, we do not have the technology to do so. That's mainly because restarting the synapses is a complex thing to do.

Answer 2

Gray gave you a decent answer. Cryogenic science is used on both live and deceased animals. When people die of a serious disease and they have $$$, they opt to be frozen a lot times and stored, so that when the technology may become available to cure them and the technology to revive them they can be brought back. Freezing things using cryogenic techniques kills the animal but places the body in a state of suspended animation. There is no tissue or muscle decay. After the body is thawed the hope is to restart it and bring it back alive again. So far our experiments have failed at this.

Speaking practically, cryogenics research is useful because if we could freeze livers and kidneys and thaw them as we needed them for transplants that would be great.
