For organs, these are typically put into cold storage until they can be put into another person, but you can only keep them for a short time before they go bad. There are some new technologies that are called “warm perfusion machines” that keep the organ at body temperature that are supposed to keep the organ healthier for longer.

Blood that people donate is usually kept refrigerated for about 42 days until it is past its “expiry” date, this is why they constantly need people donating to ensure there is enough stock of all the different blood types.

You’ve had some good answers here! Body parts need to be kept as fresh as possible and transported as quickly as possible to keep them healthy and make the swap as smooth as it can be. Organs (or other parts) in cold storage usually have to be rushed from one place to the next to reach the person who needs them quickly. Like David said, though, blood can last longer, which is good because we always need a lot of it!

I work in a blood transfusion lab and we keep a all types of blood products. Once blood id donated, they get sent to processing centres for testing and separated in to a different components such as Red cells, platelets and plasma mainly. Storage temperatures and expiry dates are purely based on the type of product. For example, red cells are kept in a fridge at 4-6oC where as platelets are kept at 20-24oc and they need to be constantly mixed, so they are kept in an agitator.
