Fresh blood typically lasts for about 42 days in the body before it gets replaced with new blood cells. However, if you're asking about how long fresh blood can be stored outside the body, it can be refrigerated for up to 42 days or frozen for up to 10 years. Just don't go trying to stock up on blood like it's a pantry item, okay?
