    Ok,i'm confused with this, a person with blood type A, they will produce B antibody, doesn't B antibody will cause RBC containing A antigens to coagulate? or causes an immune response?

    I'm moving this to the MCAT Study Question Q & A. The MD/PhD forum isn't a good place to ask these sorts of questions.

    No, if I'm remembering correctly, B antibody is against B (hence why AB can't be given either). Antigens signal what it is and antibodies signals what it wants to destroy (in a way).

    So if you have A blood type, you have B antibody so if you give B or AB blood, you'll have coagulation. B blood type can't have A. AB can have either. O can't have anything but O but can give it to anyone.

    I think you're confusing antibody with antigens? Remember it as anti-X-body where X is the blood type it is against. So if A has B antibodies, put that B in between the anti and body: ant-B-body. Helpful?

    Kaustikos is correct.
