Organs of the Immune System
These are the organs that make up the Immune system:
 Tonsils adenoids

Thymus
Lymph nodes
Appendix
Bone marrow
Lymphatic vessels
Spleen
Peyer’s patches
What does it do?
The Immune system is made up of cells, proteins,
tissues, and organs, which protects the body against
germs and micro organisms every day.
The Immune system protects the body from getting
illnesses such as bacteria and germs. Leukocytes are
released to destroy diseases.
Germs
Bacteria
What could go wrong with it?
The immune system can also cause problems in the
body. Sometimes the immune system doesn’t know
what it is fighting and it may attack the body instead of
the germs and bacteria. Some people have died from
this disease. Sometimes the immune system can create
a disease which makes it hard to fight. Because the
immune system can’t fight itself.
What do you need to keep it healthy
and working properly?
To keep the immune system working properly you need
to eat healthy to build up a good immune function.
Immunisation can also prevent diseases by the immune
system fighting germs. When you go on a holiday
overseas you need to get an inoculation which protects
the body from foreign germs.
3 Levels Of Defence
• There are three levels of defence. These are
the things that protect your body when you
get cut or hurt. These are the three levels of
defence:
• Level 1. Skin and mucous.
• Level 2. Swelling and fever.
• Level 3. Internal immune system
When an infection is at it’s greatest
Illness
When it is most dangerous
Measles
This disease is contagious at the start, there is less danger
after the rashes appear.
Chicken Pox
It is contagious from the day before the first blister, until 7
days has past the last spot goes.
Mumps
It is most contagious when the neck becomes swollen.
Whooping Cough
Unless you treat it with antibiotics there is a chance of a
infection until six weeks after the illness. If you do teat it
with antibiotics the infection will go away after seven
days.
Polio
It is infectious until you become paralysed.
Scarlet fever
It is most infectious in the first few days of the illness. It
stops being infectious after 24 hours starting with the
treatments.
Immune Response
 The immune response are the steps to killing an invader. The
immune system needs to identify the invader, kill the invader
and remember the invader for later. These cells protect your
body:
 Macrophages: surround invader put a flag to notify the T
cells.
 T cells: helper cells and tell B cells.
 B cells: Produce Y- shaped antibodies to attach to the germ.
 K cells: Destroy invader
 M cells: Remember the invader for next time.
