    Study Notes

    Key Terms

    • Active immunity: Immunity obtained through exposure to an antigen
    • Antibody: A protein produced by the body to fight off an antigen
    • Antigen: Any substance capable of inducing an immune response
    • Autoimmune: When the immune system mistakenly attacks its own body
    • Cell-mediated immunity: Immunity involving T cells attacking infected cells
    • Humoral immunity: Immunity involving antibodies produced by B cells
    • Lymphocyte: A type of white blood cell crucial in the immune system
    • Neutrophil: A type of white blood cell that helps destroy pathogens
    • Passive immunity: Immunity obtained from another source, such as antibodies from a mother to child
    • White blood cells (WBCs): Cells that defend the body against infection

    Learning Outcomes

    • Identify immunity acquired through vaccination
    • Describe two mechanisms of immunity: cell-mediated and humoral
    • Discuss the functions of different immunoglobulin classes in immune responses
    • Explain how aging affects the immune system
    • Describe subjective and objective data collection for patients with immune disorders
    • Explain nursing care for patients undergoing immune system tests
    • Discuss treatment options for immune system disorders

    Immune System Function, Assessment, and Therapeutic Measures

    • Immunity: The body's ability to destroy pathogens or foreign material, preventing infectious diseases
    • Antigens: Chemical markers identifying cells or molecules; self-antigens are tolerated, foreign ones are destroyed
    • Lymphocytes: Three types: natural killer (NK) cells, T cells, and B cells. NK cells destroy foreign cells, T cells attack, and B cells produce antibodies
    • Antibodies: Produced by plasma cells, attach to antigens, labeling them for destruction
    • Cell-mediated immunity: Targets intracellular pathogens (viruses/fungi), cancer cells, and foreign grafts using cytotoxic T cells and helper T cells
    • Humoral immunity: Targets extracellular pathogens (bacteria) using antibodies produced by B cells
    • Antibodies: Five classes (IgG, IgA, IgM, IgD, IgE) with varied locations and functions

    Additional Information

    • Immune system components include lymphoid organs, lymphocytes, and chemicals activating cells
    • The lymphatic system includes lymph, lymph vessels, lymph nodes, nodules, and the spleen; crucial in pathogen filtration and immune cell function
    • Aging affects immune system efficiency, making older adults more vulnerable to infections and autoimmune disorders.
    • Assessment of immune system includes history of allergies, medications, and past illnesses, as well as physical examinations.
    • Diagnostic tests for immune disorders include blood tests, biopsies, and skin tests, helping determine causes and diagnoses.
    • Therapeutic measures include medications, treatments to assist in immune function, and potentially surgical intervention.
