    Study Notes

    • The immune system defends the body against infections and foreign substances.
    • The immune system has three lines of defense: physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
    • Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid.
    • White blood cells, including phagocytes and lymphocytes, play a key role in the immune system.
    • B lymphocytes find targets and send defenses, while T lymphocytes destroy invaders and infected cells.
    • Antibodies are produced by B lymphocytes and lock onto specific antigens to prevent future attacks.
    • The immune system includes primary lymphoid organs like the bone marrow and thymus, as well as secondary lymphoid organs like lymph nodes and spleen.
    • There are two types of immunity: active and passive.
    • Humans have two types of immunity: innate and adaptive.
    • The adaptive immune system includes the cell-mediated immune response and the humoral immune response.
