Player Name
Function
Analogy
Explanation
Viruses, bacteria, fungus,
etc. (microorganisms) that
cause infectious diseases
Sticky or acidic fluid that
traps pathogens and kills
them
Dry flexible covering over
your whole body that keeps
out pathogens
White blood cells that
attack and destroy
pathogens entering the body
Identifying “tags” on the
surface of invading
pathogens
Eats/destroys pathogens and
saves identifying antigens to
alert other white blood cells
to start the immune
response
Immune Response
Receives signal from the
macrophage and recruits Tcells and B-cells to infected
area
Kills infected body cells to
prevent the further spread
of an infection
Makes antibodies specific to
a particular antigen found
on a pathogen
A protein produced to tag an
antigen for attack by other
cells; each one is specific to
one antigen
Sends the signal to slow
down the immune response
once pathogens are under
control
Cells that are made to
remember the antigen and
remain in the body in case
of another infection
*Extra Credit: Create an analogy for each “player” of the immune system. Explain why your
analogy fits.
