What does a Medieval Fortress have to do with the Immune System?

We’re in the midst of a unit on Infectious Disease in Cardio/Health this week.  Students have learned about 4 “bad guys” (viruses, bacteria, protozoans, and fungi) and the human body’s three lines of defense against these sinister vilains:

  1. The first line of defense is the physical and chemical barrier that is created by the skin, sweat, saliva, tears, and stomach acid.
  2. The second line of defense is Inflammation.  The main players at this line are the phagocytes.
  3. The third, final, and most complex line of defense is the immune system.  The B and T Lymphocytes are running the show at this level.

Today, we’ll create an analogy as a class in which each of the elements in the body’s defense system is represented by some element of a medieval fortress.  Think walls, motes, guard towers, scribes, etc. Each of the 4 pathogens will be represented by a different character that’s trying to attack the fortress.

I’ve got my dry erase markers ready and I’m looking forward to seeing what we come up with as a class.  Stay tuned.
