All of the following are characteristics of blood donations and transfusions that enable their extensive use for transplantation purposes except . Group of answer choices the blood components only need to function for a few weeks blood transfusion is a straightforward and inexpensive process erythrocytes do not express MHC class I or class II molecules only the ABO antigens need to be compatible between donor and recipient individuals can donate on a regular basis without any deleterious effects

only the ABO antigens need to be compatible between donor and recipient

Explanation:

An antigen is any molecule that is capable of inducing an immune response in the host (e.g., the coat protein of a pathogenic virus). The ABO blood group system is used to indicate the presence of one, both, or neither of A and B antigens on the surface of red blood cells. In blood transfusions, ABO antigens have to be compatible between donor and recipient. In consequence, it means that 1-donors of group A can donate blood to recipients with types A and AB (a recipient of group A can receive blood from a donor whose blood does not contain B antigen), 2-donors of group B can donate blood to recipients with types B and AB (a recipient of group B can receive blood from a donor whose blood does not contain A antigen); and 3- donors of group O can donate blood to recipients with types A, B, AB, or O (a recipient of group O blood can receive blood from a donor whose blood does not contain A and B antigens).
