Immunology Exam quiz with answers
graded A+
Define immunology - ANS✅✅The study of the molecules, cells, organs, and systems responsible
for the recognition and disposal of foreign materials
Who is the father of immunology - ANS✅✅Edward Jenner
What are the 4 functions of the immune system - ANS✅✅Defense, homeostasis, surveillance,
regulation
Describe the defense function of the immune system - ANS✅✅defending the body against
infections by recognizing and responding to foreign antigens
Describe the homeostasis function of the immune system - ANS✅✅removal of dead self-cells
Describe the surveillance function of the immune system - ANS✅✅removal of tumor cells
Describe the regulation function of the immune system - ANS✅✅enhancement and depression of
immune response
Describe the 1st line of immune defense - ANS✅✅unbroken skin and mucosal membrane surfaces;
secretions; physical ability to wash away potential pathogens; chemical properties of tears and saliva
Describe the 2nd line of immune defense - ANS✅✅activated immediately; focuses on a few large
groups of microbes called PAMPs; phagocytes, complement, acute inflammatory response
Describe the 3rd line of immune defense - ANS✅✅lymphocytes and antibodies; develops a
memory for the antigen
Humoral components of adaptive immunity - ANS✅✅Antibodies, cytokines
Cellular components of adaptive immunity - ANS✅✅T lymphocytes, B lymphocytes, Plasma cells
, What characteristics are needed for a "good" immunogen - ANS✅✅Foreignness, degradability,
molecular weight, structural stability, complexity
Functions of IgM - ANS✅✅First present in Primary immune response, fixes complement
Functions of IgG - ANS✅✅
Functions of IgA - ANS✅✅Major component in secretions to protect body surfaces against
invading microorganisms
Function of IgD - ANS✅✅unknown
Function of IgE - ANS✅✅mediates some types of hypersensitivity reactions, allergies and
anaphylaxis
Phases of Secondary immune response compared to primary - ANS✅✅Shorter lag, more drastic
log, plateau phase longer
Affinity - ANS✅✅initial force of attraction that exists between a single Fab site on an antibody
molecule and a single epitope or determinant site on the corresponding antigen
Avidity - ANS✅✅the functional combining strength of an entire antibody within its antigen
Immune complex - ANS✅✅the noncovalent combination of antigen with its respective specific
antibody
Sensitivity - ANS✅✅the ability of an assay to determine that samples from infected individuals are
positive for specific antibodies
Specificity - ANS✅✅the ability of an assay to determine that samples from non-infected
individuals are negative for specific antibodies
