An infection control nurse is presenting an inservice reviewing the immune response. The nurse describes the clumping effect that occurs when an antibody acts like a cross-link between two antigens. What process is the nurse explaining?
A) Agglutination
B) Cellular immune response
C) Humoral response
D) Phagocytic immune response
Ans: A
Feedback:
Agglutination refers to the clumping effect occurring when an antibody acts as a cross-link between two antigens. This takes place within the context of the humoral immune response, but is not synonymous with it. Cellular immune response, the immune system's third line of defense, involves the attack of pathogens by T-cells. The phagocytic immune response, or immune response, is the system's first line of defense, involving white blood cells that have the ability to ingest foreign particles.
