Blood Types Each contains different proteins which make donating and receiving blood complicated! These proteins are:Each contains different proteins which make donating and receiving blood complicated! These proteins are: Antigen = anything that triggers an immune response IF recognized as being “foreign”.Antigen = anything that triggers an immune response IF recognized as being “foreign”. Antibody = the proteins that recognize (match) specific antigens.Antibody = the proteins that recognize (match) specific antigens. 4 blood types:4 blood types: Type A: contains “A” antigens and “B” antibodiesType A: contains “A” antigens and “B” antibodies Type B: contains “B” antigens and “A” antibodiesType B: contains “B” antigens and “A” antibodies Type AB: contains both “A” and “B” antigens and NO antibodiesType AB: contains both “A” and “B” antigens and NO antibodies Type O: contains NO antigens but BOTH “A” and “B” antibodies.Type O: contains NO antigens but BOTH “A” and “B” antibodies.

How Do Blood Transfusions Work? The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens.The transfusion will work if a person who is going to receive blood has a blood group that doesn't have any antibodies against the donor blood's antigens. But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in the donated blood will clump or agglutinate.But if a person who is going to receive blood has antibodies matching the donor blood's antigens, the red blood cells in the donated blood will clump or agglutinate.

Blood Types: Donating and Receiving Type A:Type A: Donates to: A AND ABDonates to: A AND AB Receives from: A or OReceives from: A or O Type B:Type B: Donates to: B AND ABDonates to: B AND AB Receives from: B or OReceives from: B or O Type AB:Type AB: Donates to: AB onlyDonates to: AB only Receives from: A, B, AB, or OReceives from: A, B, AB, or O UNIVERSAL RECIPIENT!UNIVERSAL RECIPIENT! Type O:Type O: Donates to: A, B, AB, or ODonates to: A, B, AB, or O UNIVERSAL DONOR!UNIVERSAL DONOR! Receives from: O onlyReceives from: O only
