Once upon a time, in a land far away, there was a princess named Annabelle Antibody.
Nurse, I don't feel so well.
Based on your symptoms, I think you might have the flu. I'll fetch you some medicine.
Did you know that your body has its own way of fighting off germs, just like medicine?
When an antigen invades, your body has many lines of defense.
Let me explain this in an easier way!
Imagine an army trying to break into your castle. The army would represent the germ/invader and the outside of the castle would represent your skin. Your skin classifies as non-specific defense because it's not directly attacking the invader.
