- Hairs and mucus in the nose
- Hair traps pathogen
that have been
breathed in, in mucus in
the nostrils

- Trachea and Bronchi
- Secrete mucus to trap
pathogens
- Lined with cilia (hair like

- Immune System/White Blood Cells
- Consuming/engulfing pathogens
- Called PHAGOCYTOSIS

- Producing Antibodies
- Every pathogen has
unique antigens on its
surface.
- White blood cells
produce antibodies to
lock onto this specific
antigen.
- Antibodies are then
produced rapidly and
carried around the
body to find all similar
bacteria or viruses.
- If the same pathogen enters the
body again, the white blood cells
will rapidly produce the correct
antibodies to kill it.
- If the same pathogen enters the
body again, the white blood cells
will rapidly produce the correct
antibodies to kill it.

- Producing antitoxins
- Antitoxins counteract the toxins
produced by invading the bacteria
