Specific immunity is the body's learned immune response to disease-causing foreign substances, also referred to as pathogens or antigens. It is also commonly called acquired immunity or adaptive immunity.
Humoral immunity is also known as antibody-mediated immunity. It is mediated by antibody molecules secreted by the B- lymphocyte cells that can neutralize specific pathogens outside the cells. B-cells are bone marrow derived, and each cell makes only one kind of antibody which specifically reacts on a particular pathogen.
