WebHow the Immune System Works. The first time we encounter a pathogen, our bodies generate a primary immune response. Subsequent exposures, on the other hand, benefit from secondary (or memory) immune responses. As described in the " Types of Immunity" section, these responses differ in that memory responses are generated more rapidly and … WebThe ability of antibody to bind antigen also increases dramatically in the secondary response. Injecting a new antigen "B" with "A" shows that a memory or prior exposure is …
