Your Immune System
the "Department of Defense" for Your Body

Learn and EARN A REWARD!!

Antibodies Attack Cancer Cell
Your body’s immune system protects you against bad germs (called ANTIGENS) every day. In most cases, the immune system does a great job of keeping people healthy but sometimes problems can lead to illness and infection.

The immune system includes cells, tissues, and organs that work together to protect the body. The cells involved are white blood cells (called LEUKOCYTES), which seek out and destroy the antigens.   During this process, the white blood cells produce special proteins (called ANTIBODIES) to fight the antigens. 

Once produced, antibodies continue to exist in a person's body, so that if the same antigen is presented to the immune system again, the antibodies are already there to do their job. So if someone gets sick with a certain disease, like chickenpox, that person typically doesn't get sick from it again.

This is also how immunizations prevent diseases. An immunization introduces the body to an antigen in a way that doesn't make someone sick, but does allow the body to produce antibodies that will then protect the person from future attack by the germ or substance that produces that particular disease.

Your body – an amazing creation!

Do some research and EARN A REWARD!

Students in Alabama are typically required to have the following immunizations before entering school:

  • Diptheria
  • Tetanus
  • Pertussis
  • Polio
  • Mumps
  • Rubella
  • Measles
  • Varicella

Pick any two of the diseases listed above.  Do some research on each of the two diseases you select to find out the following:

  1. What is the Cause of the Disease?  (how do you get the disease?)
  2. What are the Symptoms of the Disease?
  3. What is the Treatment if you have the Disease?

Record your answers on paper and turn in to Mrs D by class on Friday, 15 March to EARN A REWARD!!
