Immunity

Innate Immunity
Prevent: pathogens from getting in
skin: is dead and prevents everything from passing through
Mucus: openings have mucus that traps pathogens
Bacteria: have these inside tracks. they destroy pathogens
if that fails
Destroy: if they get in tissue and blood
Neutrophils: White blood cells that sence pathogens, rush to them, suround them, engulf them, and destroy them.
Macrophages: engulf and destroy pathogens as well.
Swelling traps pathogens and killers.

Aquired immunity (the lymphocytes)
T-cell:
helper T-cell: comands the killer T-cells and instructs the B-cells.
Killer T-cell: Reanforcmants the engulf pathogen.
B-cell: make antibodies
antibodies: Specific to pathogens they are Y shaped, they attach to the pathogen to signal destroyers.
Memory B-cells: remembers the specific pathogens so it can imobalize quicker next time.
