I'm the FIRST to respond when there's a threat, using general protection to keep away bad bacteria!

Now Isaac will answer some questions we all want to know about the Immune System!

What body organs help the Immune System?

The red bone marrow, thymus, spleen, and tonsils all play a role in helping the Immune System!

What happens when the Isaac and the Immune                             triplets make a mistake?

Sometimes when we confuse the healthy body cells for bad bacteria and attack them it means we made a mistake, this is called autoimmune disease. 

What is an allergen?

Allergens are things that can cause the body to have an allergic reaction. One example of an allergen is pollen!
