Current Question (ID: 14443)

Question:

During 'Erythroblastosis fetalis' there is

Options:

1. Foetal stem cells fails to form RBC.
2. RBC fails to transport O₂ to foetal tissues.
3. Agglutination and phagocytosis of RBC.
4. RBC fails to develop Rh antigen on its surface

Solution:

During 'Erythroblastosis fetalis' there is agglutination and phagocytosis of RBCs due to the incompatibility of the blood group antigens between the mother and the fetus. This condition occurs when an Rh-negative mother carries an Rh-positive fetus, leading to the production of antibodies by the mother's immune system that attack the Rh-positive red blood cells of the fetus.
