The
immune system
destroys
pathogens
and any
toxins
they produce.
The immune system protects is incase the same type of
pathogen
invades us again in the
future.
White blood cells
can
ingest
and
destroy
pathogens.
Phagocytosis
The
white blood cell
detects chemicals releases from the
pathogen
and moves
towards
it.
The
white blood cell ingests
the
pathogen
and once
ingested
, the
white blood cell
uses
enzymes
to
destroy
the
pathogens.
Antibodies
are
protein
molecules produces by
white blood cells.
The
antibodies
stick to the
pathogens.
This
triggers
the
pathogens
to be
destroyed.
Antibodies
are
extremely specific. Antibodies
are developed for a
specific pathogen
and they will not
protect
against other
pathogens
Antibodies
will remain in the
blood
for a
long time
, meaning they can
protect
is incase we ever got
infected
again with the same
pathogen.
White blood cells
can produce chemicals called
antitoxins.
Antitoxins
stick to
toxin
molecules and
prevent
them from
damaging cells.
