1.
Select the statements that correctly describe the role of the
thymus, spleen, and lymph nodes in adaptive immunity. Select
the TWO answers that are correct.
The thymus is the site of T cell development.
The thymus and lymph nodes work together in humoral
immunity.
The thymus and spleen produce B cells.
Lymph nodes and the spleen filter pathogens from lymph and
blood.
The lymph nodes secrete lymphatic fluid.
2.
How do humoral immunity and cell-mediated immunity differ?
Select the TWO answers that are correct.
Humoral immunity involves mainly B cells, whereas cell-mediated
immunity involves mainly T cells.
Humoral immunity is an innate immune response, whereas
cell-mediated immunity is an adaptive immune response.
Humoral immunity targets antigens that circulate in blood and
lymph, whereas cell-mediated immunity targets abnormal cells.
Humoral immunity involves mainly T cells, whereas cell-mediated
immunity involves mainly B cells.
Humoral immunity responds to viral infection, whereas
cell-mediated immunity responds to bacterial infection.
3.
Select statements that correctly describe the functions of
lymphocytes in cell-mediated immunity. Select
the TWO statements that are correct.
Phagocytes make many copies of a specific antibody.
B cells recognize antigens and divide into plasma cells.
Memory B cells retain antibodies to respond to future
infections.
Memory T cells enter circulation to recognize future
infections.
Cytotoxic T cells kill pathogens and abnormal body cells.
4.
Select statements that correctly describe interactions between
antibodies and antigens. Select the TWO statements that
are correct.
An antibody on the surface of a B cell recognizes and binds to
a specific antigen on the surface of a pathogen.
An antibody is an immune protein that circulates in body fluids
that binds to an antigen on the surface of a pathogen.
An antibody is a surface protein of a pathogen that is
recognized by an antigen on a lymphocyte.
An antibody is a lymphocyte that rapidly divides into plasma
cells when it detects an antigen.
An antibody is a complex and versatile protein that recognizes
and binds to many different antigens.
5.
Select the statements that correctly describe the role of B and
T cells. Select the TWO answers that are correct.
B cells form the lymph nodes.
T cells make up the thymus.
B cells produce antibodies.
T cells destroy infected cells.
B cells stimulate T cells.
6.
What is a memory cell?
a lymphocyte that recognizes a specific antigen long after
initial exposure to the pathogen
a B cell that binds to antigens that are structurally different
from the initial antigen
a T cell that supplies B cells with antibodies that match an
antigen from a previous infection
a phagocyte that binds to a specific antigen and engulfs the
cell with that antigen
a plasma cell that releases large amounts of a specific
antibody into the bloodstream
