2. Introduction
• White blood cells, also known as leukocytes, are
responsible for protecting your body from
infection.
• As part of your immune system, white blood
cells circulate in your blood and respond to
injury or illness.
3. What do white blood cells do?
• White blood cells protect your body against
infection. As your white blood cells travel
through your bloodstream and tissues, they
locate the site of an infection and act as an army
general to notify other white blood cells of their
location to help defend your body from an attack
of an unknown organism.
4. How are white blood cells formed
• White blood cells originate from cells that
morph into other cells in the body (stem cell)
within the soft tissue of your bones (bone
marrow)
• If you have a low white blood cell count,
you are likely leukopenia.
• If your white blood cell count is too high
leukocytosis

6. What are the types of white blood
cell
•
There are five types of white blood cells:
• Neutrophils: Help protect your body from infections
by killing bacteria, fungi and foreign debris.
• Lymphocytes: Consist of T cells, natural killer cells
and B cells to protect against viral infections and
produce proteins to help you fight infection
(antibodies).
• Eosinophils: Identify and destroy parasites, cancer
cells and assists basophils with your allergic response.
• Basophils: Produces an allergic response like
coughing, sneezing or a runny nose.
• Monocytes: Defend against infection by cleaning up
damaged cells
