Active immunity: Resistance to disease resulting from the activities of an individual's own immune system.
Agglutination: The "clumping together" of pathogens by antibodies, facilitating phagocytosis.
Antibody: Protein produced by B lymphocytes which binds to antigens on pathogens.
Antigen: A molecule (usually a protein) which triggers an immune response.
B lymphocyte: White blood cell involved in humoral immunity, which produces antibodies and stores immunological memory of antigens.
Immunity: The means by which the body protects itself from infection.
Lymphocytes: White blood cells involved in the specific immune response (B cells and T cells).
Lysosome: An organelle containing digestive enzymes.
Macrophages: White blood cells which carry out phagocytosis.
Monoclonal antibodies: Antibodies produced from a single clone of B cells.
Passive immunity: Resistance to disease acquired by the injection of antibodies into the body
Pathogen: A disease-causing microorganism.
Perforin: Protein produced by cytotoxic T cells which kills infected cells by perforating their plasma membrane.
Phagocytosis: Mechanism by which pathogens are ingested by macrophages.
Phagolysosome: a phagosome fused with a lysosome.
Phagosome: a vesicle in a macrophage containing a pathogen.
T lymphocyte: White blood cell involved in cell-mediated immunity, coordinating the immune response and killing infected cells.
Vaccination: The introduction of a vaccine containing antigens into the body to induce artificial immunity.
