How is human blood separate from that of animals? Why can't animal blood be administered to Humans?

Answer 1

Three letters.....DNA
All species have different DNA. But the Homiosapian and Apes DNA is different in only 1 chronisom strand. I bet some day they will be able to intermix DNA from Humans and Apes and viseversa.

Answer 2

Not even every human blood can be administered to another human. The blood groups must match. It has to do with your body rejecting foreign elements if they are not exactly as yours.
Same reason why organ transplants are very hard to do because of the risk of rejection from your own organism.

Answer 3

Blood is living tissue, just as organs are. In fact, as a classification, your blood IS an organ. Those blood cells have all the complexity of human tissue, and you know you can't transplant organs from one species to another except in very extreme cases. (It can be done to some extent with very simple organisms, but it's not natural, certainly.) They simply are not accepted by the body as anything other than ALIEN INVASION!!! CALL OUT THE DEFENSES!!! EJECT!! REJECT!!! And the body throws it off, usually not without some damage to itself along the way.

Answer 4

Even among humans, blood is not always compatible. You might do well to seek information on human blood types. Mainly, it's the same reason we can't use their internal organs, otherwise, we would all be walking around with baboon hearts and pig livers. As my cataracts progress I might consider the exotic appeal of cat's eyes, but alas, this is not to be. The horseshoe crab has blood different than any other living creature, it is copper based and they bleed green blood. Go and figure.

Answer 5

Had the animal blood be transfused into human beings, they would have been jumping like monkeys.
