Type B and O.
With type A and AB, the blood would resist the transfusion and clump up.
You are able to receive type A, type B and type AB you can receive any type of blood.
Type O can receive type O. Type A can receive type O or A. Type B can receive type O or B. Type AB can receive type O, A, B, or AB.
B and O
More than just two blood types are not compatible with each other. The four basic types of blood are: A, B, AB, O(not counting Rh). Type A blood can only receive blood from type A and type O. However, type A blood can donate their blood to type A and type AB. Type B blood can only receive blood from type B and type O. However, type B blood can donate their blood to type B and type AB. Type AB blood can receive blood from every type, A, B, AB, and O. However, type AB blood can only donate to other AB. Type O blood can only receive blood from type O. However, type O can donate their blood to A, B, AB, and O. So, AB is the "universal" reciepient and O is the "universal" donor.
FALSE B CAN ONLY RECEIVEVE O AND B SAFELY BECAUSE OF THAT A IN AB, THEMPERSON CAN'T RECEIVE IT
No...someone with a B blood type has anti-A antibodies so the A blood type in the AB blood would cause clotting.
They can only donate to other AB types, but they can receive blood from A, B, or O.
An antigen is a substance, usually a protein or a http://www.answers.com/topic/glycoprotein, which, when injected into a human (or other organism) that does not have the antigen, will cause an http://www.answers.com/topic/antibody to be produced. Antibodies are a specific type of immune-system proteins known as immunoglobulins, whose role is to fight infections by binding themselves to antigens. basically this means that different blood types have antigens in them and if they mix then they attack one another
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.
Antibodies. They are designed to resist, or fight, specific types of antigens. Type AB has no antibodies, which is why they can receive any type of blood. Type A has B antibodies, which means it will fight type B blood as well as type AB. Type B has A antibodies, which means it will fight type A blood, as well as type AB. Type O has A and B antibodies, which is why it can only receive type O blood.
Blood types A and B are incompatible because a type A person has naturally occurring Anti-B in his blood and a type B person has naturally occurring Anti-A. Thus a type A person can not receive blood from a type B person because the naturally occurring anti-A would destroy the type A person's red cells. The converse is true for a type B person who can not receive type A blood since the Anti-B found in the type A blood would destroy the type B person's red cells.
blood type O can give to anyone because they are the universal donor. and blood type AB- can give to blood type AB-. *Another user says... Because the rhesus factor is negative, this blood type can receive any type of blood other than the types with positive rhesus factors. In other words, O-, A-, B-, and AB-. Hope this helps!
