Rh D - negative individuals generate an immune response when they are exposed to the Rh-D antigen. However, incompatibility in the ABO blood group system occurs naturally in the presence of exposure to the A or B antigen in the blood from individuals.

Rh-D-negative individuals generate an immune response when they are exposed to the Rh-D antigen. However incompatibility in the ABO blood group system occurs naturally in the absence of exposure to the A or B antigen in the blood from another individual. why do individuals produce an immune response the first time they encounter the A or B antigen as an adult.

If the thymus of an adult experimental animal is removed, the following observations can be made: (a) No immediate effect occurs, and (b) after 1 year, decreases occur in the number of lymphocytes in the blood, the ability to reject grafts, and the ability to produce antibodies. Explain these observations.
How do humans produce antibodies to blood group antigens to which they have not previously been exposed? briefly explain
What antibodies does a person with B+ blood contain?
What is meant by the “window” regarding antibody presence in the blood?
How does the general principle of physiology apply at the molecular level in the case of immunoglobulins?
Rh-D negative individuals generatean immunne response when they are exposed to the Rh-D antigen.

In terms of antigens and antibodies, explain why O- is considered a universal donor and why AB+ is considered a universal recipient. Even so, why can’t whole blood O- be donated to a person of type AB+ blood?
If a person is given a transfusion with the wrong blood type, what mechanism of action is responsible for the reaction seen in the body? O 1) IgE binds to mast cells releasing cytokines 2) Antigen-antibody complexes (IgG, IgM and IgA) lodge in basement membranes of tissues, neutrophil degranulation damages the tissues O 3) T cells respond to the inappropriate cells 4) IgG and IgM bind to cells stimulating complement, triggering cell lysis
Why is it that Rh incompatibility can be a serious problem when anRh-negative mother is carrying an Rh-positive fetus, but ABOincompatibility between mother and fetus is usually no problem?That is, a type A mother can usually safely carry a type B fetus.(Hint: The antibodies produced by an Rh-negative mother againstthe Rh antigen are usually IgG, whereas the antibodies producedagainst the A or B antigens are IgM.) Because the Rh antigenobviously serves no vital function (most humans lack it), why do youthink it hasn’t been completely eliminated during human evolution?
