Question

Quizplus · Accepted Answer

Antibodies dissolved in body fluids, such as blood and lymph, bind to specific antigens on the surface of pathogens or other foreign substances. This binding then triggers a series of responses that help eliminate the antigen from the body. These responses can include neutralization of the antigen, opsonization to make it more easily recognized by immune cells, and activation of complement proteins to initiate a cascade of events that lead to the destruction of the antigen. The antibody-mediated immune response is one of the main ways that the body defends against infections by bacteria, viruses, and other pathogens.
