76 Multiple choice questions
Term 1 of 76
What is the primary function of CD4+ effector cells?
phagocytosis of pathogens to eliminate infections
production of antibodies to neutralize toxins
secretion of cytokines to activate B cells
regulation of blood sugar levels in the body
Term 2 of 76
What type of effector cell can kill tumor cells (or virus-infected cells) due to decreased MHC I
expression on the surface of the host cells?
Natural Killer cell
Basophil
Macrophage
Eosinophil
Term 3 of 76
The TCR alpha-beta heterodimer neither recognizes antigens nor is able to transmit
biochemical signals to the interior of the cell and so is redundant.
True
False
,Term 4 of 76
Cell-Mediated Immunopathology causes tissue damage and:
antigen presentation and phagocytosis
recognize MHC I.
All of the Above
Both B and D
Term 5 of 76
I make people sleepy, live in the bloodstream, and rapidly shift my surface proteins so that
they are one step ahead of the antibody attack. I am primarily found in Africa where I am
transmitted by the tsetse fly. Who am I?
Trichomonas
Plasmodium
Leishmania
Trypanosoma

Which of the following is NOT a peripheral lymphoid organ?
Spleen
Spongy Bone
Bone Marrow
Macrophages
,Term 8 of 76
I am a large fixed phagocytic cell that kills microorganisms, secretes cytokines, and presents
antigen to helper T lymphocytes in the tissues. I am a:
Lymphocyte
Eosinophil
Macrophage
Neutrophil
Term 9 of 76
T and B lymphocytes specifically recognize antigens.
True
False
Term 10 of 76
The main hemodynamic changes in inflammation are:
To allow products of the immune response to enter area of infection or damage
All of the above
The production of exudates and increased permeability
Secretion of cytokines to activate b cells
Term 11 of 76

Term 13 of 76
Antibodies are produced after stimulation of B lymphocytes by antigens in the peripheral
lymphoid organs.
True
False
Term 14 of 76
Two processes that occur in a B cell during an antibody response to antigen that help to make
that response more effective are:
Both b and d
Differentiation into subtypes
Secondary lymphoid organs
Affinity maturation and isotype switching
Term 15 of 76
Heavy chain class (isotype) switching and affinity maturation enhance the protective functions
of antibodies.
True
False
