Detailed explanation-1: -Antibodies secreted by B cells are a crucial weapon of the adaptive immune response. They are specific for the pathogen that is attacking, so they can bind to and neutralize it.
Detailed explanation-2: -Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.
Detailed explanation-3: -An antibody, also known as an immunoglobulin (Ig), is a protein that is produced by plasma cells after stimulation by an antigen. Antibodies are the agents of humoral immunity; they are the weapons the B cells use in their attacks on pathogens.
