The blood types of humans are broken up into 4 ABO groups and further by Rh (Positive or Negative). Therefore, there are a total of 8 Blood groups: O positive, O negative, A positive, A negative, B positive, B negative, and AB positive, and AB negative. The A and B refer to antigen or "receptors" on the red cells. Therefore, O red cells have neither A nor B antigens on their red cells, and can be given to everyone, while AB red cells have both A and B antigens, and can only be given to AB people. The reason for this is that every person has antibodies to the opposing red cell other than their own. Thus, an A type person has B antibodies, while a B type person has anti-A antibodies, and an O person has anti-A and anti-B antibodies. An AB type person can receive all types of blood. However, a compatibility test must be performed prior to transfusion, known as a crossmatch, using the recipient's serum (with antibodies) against the donor unit's cells (the antigens). If no reaction takes place, the cells are compatible with the patient and can be transfused. If there is a reaction (agglutination, or clumping of the red cells in the patient's serum) then the unit it not compatible and should not be transfused.

The role of science is neither to accept or reject religion. These are two separate areas of human endeavor.
Not at all. Cows have a completely different type of blood from what a human has, thus cannot be transfused from a bovine into a human without the blood from that cow being rejected by the body of that human.
Blood type during donations is asked because it is critical that blood types are matched. There are 4 human blood types: A, AB, B, and O. AB and B people can only accept their own blood type and O. A can receive all three other blood types. O can only receive it's own. If you get the wrong blood type you can die.
They aren't hiv acquired through donated blood have been human errors and not because they are allowed to donate blood.
No. If the contact with the human is brief, the doe will still accept her kid back. If the kid has been taken away from the nanny goat for a couple days, then yes, there's a risk that the doe will reject her kid.

Drinking human blood induces vomiting. Except for vampires. Blood is never blue! Deoxygenated blood is light red and oxygenated blood is dark red. Thousands of pints of blood donated to the Red Cross during Katrina were wasted. You can buy pig blood at your local super market or butcher.
No, the human body would reject it.
