Answer:
Defense against a particular antigen is provided by adaptive immunity which is also called specific immunity. In adaptive immunity immunological memory is created which is used by immune cells to destroy that particular pathogen when it again comes in the body.
Adaptive immunity involves T cells and B cells. T cells generate cell mediated immune response and B cells generate a humoral immune response. These responses by T and B cells are specific to a particular pathogen which results in the killing of the pathogen by their phagocytosis enhanced by antibodies or by direct killing of pathogen.
Therefore adaptive immunity provides defense to the body against a particular pathogen by generating immunological memory.

that it's nothing, or else that it's something that should be treated because
it doesn't belong there.
