Studying Disease Revision Notes
- Preventing Disease
- Pathogens
- Bacteria
- Multiply rapidly in warm
and moist conditions.
- Microscopic.
- Living cells.
- When they enter the body,
they release toxins that
make humans feel ill.
- Multiply rapidly in warm
and moist conditions.
- Fungi
- Larger fungi include
moulds and mushrooms
- Larger fungi include
moulds and mushrooms
- Viruses
- Genetic material inside a
coat of protein.
- Passed through bloodstream.
- Genetic material inside a
coat of protein.
- Disease-Causing Microbe
- Parasites
- Can cause disease in humans
- Can cause disease in humans
- Bacteria
- White Blood Cells
- Produce antibodies to
destroy pathogens
- Bought in when first line of
defence is broken
- Bought in when first line of
defence is broken
- Type 1: Surrounds and digests the microbes
- Types 2: Produces chemicals called
antitoxins
- Type 3: Produces chemicals
called antitoxins, which
neutralise poisons (toxins)
- Type 4: White Blood Cells produce
another type of White Blood Cell called a
memory cell, this usually means that you
rarely get the disease again as the
antibodies are produced quicker.

- NOTE
- Pathogens are not the disease, they CAUSE the disease.
- The period between when the person becomes
infected and when the symptoms of the disease start
to show is called the INCUBATION PERIOD
- Pathogens are not the disease, they CAUSE the disease.
- First line of defence is the SKIN
- When you cut or graze yourself the skin is broken so now
the microbes can enter the blood, to prevent this the
blood will clot, dry and go hard. This forms a SCAB

- Pathogens
- Micro-Organisms
- Types: Virus, Bacteria, Fungi and Parasite
- Killing Micorbes
- Disinfectants work by killing the microbes ,
they can kill living cells so they shouldn't
come in contact with human tissue.
- Antiseptics can be used on human tissue
because they stop the microbes growing,
some antiseptics are weakened forms of
disinfectants.

- Types: Virus, Bacteria, Fungi and Parasite
- Vaccinations
- Weakened form of the disease
- Given as an injection
or as a drink (polio)
- When the vaccine enters the body it triggers the
immune system to respond, white blood cells
produce antibodies to attack the microbe. The
body now has defence against the microbe:
Antibodies/ Special White Blood Cells called
Memory Cells. If microbe then attacks the body
then the memory cells produce antibodies to
attack it quickly.
- There can be
side-effects
- Weakened form of the disease
