What happens after you donate blood?

What happens several hours to weeks after you've donated, in a physiological sense? (Like, does there exist a timeline of the body's responses to lost blood/donation?) Does your body replace the lost blood with fluid until it can recreate lost blood cells? How long does this take? How long until your blood is back to "normal"?
Also, I have a really rare blood type, AB negative. Is my blood "better" for someone with the same blood type than say, O negative? I guess I'm hoping that it's worth it for me to come in despite the low number of people who have my blood type.
