Natural acquired active immunity:
Artificial acquired active immunity:
Natural acquired passive immunity:
Artificial acquired passive immunity:
Innate immunity:
Weakened germs given so the body can create resistance to a certain
disease. (e.g. Measles, Mumps and Rubella vaccine)
When you become immune by actually having the infection and the body is
able to recognise the same infection and kill it without you experiencing any
symptoms. (e.g. chicken pox)
When antibodies are passed from mother to baby during pregnancy. (Not
an everlasting immunity)
Not a specific immunity, such as the skin, tears, stomach acid.
Short-term immunization by and injection of antibodies into the system,
which will not give lasting immunity (e.g. Tetanus)

True or False?
 To avoid the cold you shouldn’t wear tight clothes or tight
shoes.
 Coughing and sneezing was banned in public during the
Plague.
 Staying out in the cold without a coat causes pneumonia.
 A white moth in the house meant death long ago.
 An onion cut in half and placed under the bed of a sick person
will
draw off fever and poisons.
 Maggots can be used to clean out wounds.
The maggots only
eat dead or infected tissues.

their surgery.
 If you go outside with wet hair you’ll catch a cold.

Complete the flow chart about how the body
fights infection
Bacteria can get through
the barriers and enter the
body through cuts &
scratches or in the food
we eat and the air we
breathe.
Bacteria reproduce
quickly, threaten
cells and can block
vital organs.
If the bacterial invasion
can't be stopped, more
phagocytes from other
parts of the body travel
in the blood vessels to
help.
B cells multiply into billions
of cells, which bind to the
invader and destroy it. T
Cells identify and destroy
any human cells which may
have died or changed or
those which it recognises as
non-human.
Some B & T cells produced
live on after the first attack
and help the body fight
against a second attack
should it occur. You are
therefore immune to these
bacteria

Phagocytes are a group of
white blood cells found in
bone marrow that can
move and ingest invaders
until they themselves burst
and die.
B cells are one kind of
lymphocyte, (white blood
cells) covered with
chemical feelers called
antibodies, which seek out
and investigate invaders.
Skin is waterproof and airtight; it
excretes oil, which contains
chemicals. Tears wash away
micro organisms, hairs in the
nose filter air and coughing and
sneezing expel micro organisms.
Stomach digestive juices can kill
some organisms that enter
through the mouth.
