    Study Notes

    Lymphoid Origin

    • Eosinophils are not lymphoid in origin
    • B cells are lymphoid in origin

    Primary Lymphoid Organs

    • Bone marrow is a central/primary lymphoid organ
    • Lymph node, spleen, tonsil, and appendix are not primary lymphoid organs

    Complement System

    • C3 convertase is C3bBb
    • C4b2a3b, C4b2a, C5, and CI are not C3 convertase

    Antibody Effector Functions

    • Opsonization is an antibody effector function
    • Neutralization is an antibody effector function
    • Complement activation is an antibody effector function
    • ADCC (Antibody-Dependent Cellular Cytotoxicity) is an antibody effector function
    • Linked recognition is not an antibody effector function

    B Cell Activation and Antibody Secretion

    • IgM is the first antibody secreted by activated B cells
    • IgA, IgD, IgE, and IgG are not the first antibody secreted by activated B cells
