macrophage
antigen
Body's Radar Type of cell normally present in
the blood Detects the enemy
The Enemy Invader Usually a bacteria or virus.
Immune response
14
The T-Helper CellCommunication Link Between the
body's macrophages and b-cells
The B-CellThe War Factory Produces antibodies
custom tailored for the type of enemy antigen
AntibodiesAntigen Busters Designed to seek and
destroy the specific
15
ComplementSupport Troops Assists the antibodies
to neutralize the enemy antigen
Immune ComplexWhen antibodies and complement
attack the antigen, an immune complex
PolymorphDisposal Unit Detects the immune
complexes and removes them
16
T-Suppressor CellAnother Communication
Link Signals to the b-cell to stop making
antibodies once the antigen has been destroyed
