    GlossaryAdaptive Immunity

    system learns to recognize and remember specific pathogens

    Adaptive immunity, also known as acquired immunity or specific immunity, is the part of the immune system that learns to recognize and remember specific pathogens. Unlike innate immunity, which provides a general defense, adaptive immunity tailors its response to each unique invader, improving its effectiveness over time. This system involves specialized cells like T cells and B cells, which can remember past infections and provide a faster, more robust response upon subsequent exposures.
