why type A blood should not be mixed with type B blood?

Question

I should know this, but I don't. I need to know tomorrow for a test, but my book doesn't have it in it and professor wont tell us because we should "already know this". Any help me out? Thanks!

Answer 1

Antibodies will be made, you will attack your own blood and die if given an inappropriate blood type in your transfusion.

Answer 2

O type has no extra group attached so it is accepted by all the other types. (one researcher thinks all blood for donations should be chemically changed to O since it is gentler) A and B have different groups and the immune system sees the odd group as an invader and fights off the blood. Now the new blood is useless and there may be side effects from exciting the immune system.
The RH factor is similar group. Since the negative people have no group it is Okay to give RH - to positive people, but not the reverse.
Hope this helps. I suppose the professor is looking for something specific. It might be wise to check you notes, book, before the test.

Answer 3

The reason is:
On the surface of A blood group, there's an antigen A.
A blood group produces antibody-B,which only reacts on antigen-B

On the surface of B blood group, there,s an antigen B.B blood group produces antibody-A,which only reacts on antigen-A.

So, when you mixed up A blood group with B lood group, agglutination will occur.This is because the A blood group produced antibody-B that reacts only on antigen B, which are present on B lood group surface.The antibody-B, produced by the A blood group identified B blood group as foreign substance and 'attack' it and clump together(agglutination).

As for AB group, it have antigen-A and antigen-B but does not produced antibody-A and antibody-B.So, this is why a patient who is from O blood group can gets blood tranfussion from either A blood group people,B blood group people, AB blood group people and O blood group people.The reason is the A,B and O blood groups introduced into his/her body does not produced enough antibody to cause agglutination.
You must remember, the antibody only present in the plasma.So, in the hospital, people will only get whole blood if the conditions is worsening.If not, the will give them a specific components of the blood(red blood cells only or white blood cells only or plasma only).


As for O blood group people, their blood does not have any antigen-A or antigen-B but produced antibody for both A and B blood group.This makes the O blood group people can only received blood from other people that have the same blood group or else agglutination will occur.But, O blood group people can donates their blood to anyone because their blood does not have antigen-A and antigen-B on it's surface.

I hope my simple answer answered your question.Good luck for your exam!!!

p/s: do me a favor.Check my grammar too coz im sux with grammar.Why? Well, English is not my 1st language.It's my 3rd language.Im on my way up to improve my language.

Answer 4

The body would reject the blood and would attack it with Blood cells

Answer 5

They are two different blood types and when combined would clot.
