Watch everything that goes down and remembers. Exists
for a long time so that they can be cloned in case the
foreign invader returns.
Plasma Cells
Army of Clones equipped with antibody machine
guns that zap everything (eventually die and break
down after victory)
T-Lymphocytes
(Made in Thymus Gland)
Natural Killers
Also called Cytotoxic T-Cells
By injecting poison, kills cells that have changed their MHC Marker due to
changes in DNA (like cancerous cells) and cells that have become ill and dropped
their MHC Markers.
Helper T-Cells
Communicators
Help identify the captured invaders and also send Interleukin Messages
Also alerts
Memory T-Cells
Hang around for future reference after the battle, just like helper B-Cells
Nonspecific Immune System (Innate)
Phagocytes
Neutrophils
Small, dies quickly (white pus in a wound
= corpses)
Macrophage
Large, takes longer to die (can be
linked to a general area or a specific
tissue)
Sends a...
Skin (Epidermis) Blocks Stuff
MHC Marker (Cell's ID Card)
If foreign, a Macrophage will eat the
bacteria/cell it's connected to and display it for
a Lymphocyte to ID and kill.
