Ok or why can’t we donate blood like we do organs? What I mean exactly is why can’t we harvest/drain a newly deceased body off all its blood and platelets? With the amount of people who pass everyday surely there would be enough.

As people die their organs tend to fail, breaking down and releasing wastes and toxins into the blood stream. If someone dies from something other than trauma it is unlikely their blood is going to be any good. Someone could also die while being treated with a combination of drugs that you really don’t want to transfer on to someone else, or if they died while not being treated it isn’t likely they would be found while their blood was still viable anyway. And finally if someone does die from trauma it is likely their blood is elsewhere like on the ground.
Mainly though there is no reason to try harvesting blood from dead people along with all those dangers when there are plenty of healthy people around who are willing to donate blood. The norm for situations where blood donations are needed is that there is an *excess* of blood and a lot needs to be thrown out after going bad. Giving blood is very safe, easy, and something that can be scaled up in an emergency. We don’t need corpse blood.
