What happened if you pull a body out of cryo??

Been trying to find pictures or info on it. Can't find shit.
What happens to organic matter after it is frozen to super low temps for long periods than brought back out?

it gets defrosted

If not done carefully, the frozen cells/parts of bodies can break and kill the party involved

Ok, but what state will the matter be in? What level of decomposition happens if you pull them out and let it defrost?
>Does it go back to the level it was at when the person died? Or does the body decompose differently than a regular body would if defrosted after being frozen?

Frozen crystals inside the cells of the organism will break the cells apart the organism will die out. Then there's the amount of extra water inside the cells that may cause cells to burst open.

From what I have read on the process, the process of cryonics was supposed to prevent that from happening.

We haven't perfected cryonics or restoration from cryonics.

I did not mean the restoration part. I am aware they are corpses.

But they are not just putting the corpses on a freezer.

They more or less do. That's why it is all kinda bullshit.

So, has anyone tried injecting the bodies with chemicals similar to what amphibians use during hibernation, or do they just freeze them raw?

if they were capable of being revived they would probably suffer from something akin to radiation sickness and quickly die

Unsure. I hope cryonics is developed enough by the time I'm 90 (currently 25 and very healthy, long family history of ancestors living into mid 90's quite regularly) that I at least have a small chance of coming back. Considering that 60 years ago cryonics was literally putting people into a fucking freezer and that's it, I'm hopeful. I'm sure some anon will reply with a source showing I'm fucked anyway.

The ones we have frozen are pretty much useless. Freezing causes crystals, crystals brake cell membranes. Freezing it fast will make smaller crystals and creates less damage. I'm pretty sure we are kinda good at doing this to small bio samples but a whole human has a bit different mass to surface area ratio so you can't just freeze it from the outside.
It will probably look ok for a short time and turn into rotten goop in no time. Just like frozen food is ok to eat after melting but turns bad really fast.

So since the difference in temperatures and a large bio sample seems to be a key problem, this logic would dictate anyone interested in cryo would actually have a better chance of good preservation if they opted only for the head storage vs. full body?

They are called cryoprotectants but they are toxic. Some mixes are safe enough that we use them with stuff as big as organs but I have no idea how long you can store stuff with that and how you get rid of the toxic stuff.

You can get rid of the toxin or adapt the body to thrive on the toxicity

Yep. That's pretty much why there is a whole field of science dedicated to studying animals that can survive freezing.

1.) Enlighten world population to abandon their primitive ways
2.) Analyze personalities of all earth residents; plan for extreme attempts at subversion because evil will always attempt to ruin the potential of good
3.) Build many massive fully insulated underground facilities away from all tectonic activity but within range of uninterruptable thermal energy source
4.) Invent quantum computers
5.) Invent scanning array capable of making 1 to 1 database of all 37.2 trillion cells
6.) Invent surgeon capable of stitching 37.2 trillion cells back together after exploding from ice crystals

We are on step 5

Why do they have to be crazily frozen? Is there no way to avoid the ice crystals? A throbing of the temperature, so it lowers before the crystals form.

Or a way to constantly introduce all new cells, to constantly be transferring over,

Yes we are. Cryonics only works with small cells, freezing an entire body is impossible with current technology. If we ever find a way to freeze and unfreeze bodies, I bet those that are already frozen today will be way too damaged

What if we replaced blood with super-cold non-toxic antifreeze solution of some kind? How fast can an exchange transfusion machine cycle the blood out? Maybe that could flash-freeze a body from the inside out. Maybe rapidly fill the alimentary canal and respiratory/sinus system with the same fluid too without rupturing anything.
