3.1.1 Germ Theory of Disease
L.O: to recall knowledge from GCSE about
disease and immunity
to categorise diseases
to describe how the body defends
itself against disease
**Stick in ‘3.1.1 overview’ sheet **
Starter: List all of the illnesses you’ve had in
your life (e.g. tonsillitis)

WHO Top 10 Causes of Death
• Look at the data from high income and low
income countries
• What conclusions can you come to?
Infectious Diseases
Caused by pathogens…
• Define a pathogen
• State the different types of pathogen
• List how pathogens can enter the body (e.g.
food)
Infectious Diseases
Caused by pathogens…
• Define a pathogen: a micro-organism that
causes disease
• State the different types of pathogen:
bacteria, virus, fungi (and protist)
• List how pathogens can enter the body:
Food, airborne droplets, water, cuts/grazes
How the Body Defends Against
Pathogens…
• Draw the outline of a body (NOT a
stickman!)
• Label how the body keeps pathogens out
(e.g. ear wax)
How the Immune System Defends
Against Pathogens…
• What can you remember about the
immune system and how it works? (Hint:
what three processes do white blood cells
do?)
How the Immune System Defends
Against Pathogens…
White blood cells
Produce antibodies
Produce antitoxins
Engulf pathogens
