Medicine 36: How Our Immune System Fights Infections


Grade Levels:  6 through 12

Our bodies have a magnificent immune system consisting of a powerful army of killer cells and protective proteins.  This powerful defense system is primed and ready to go within a few seconds of encountering a possible infecting bacteria, virus, or parasite.  These “pathogens” try to outsmart our immune systems and sometimes succeed.  Learn how your immune systems works in a fun, engaging, and insightful program with Dr. Kathryn Tristan.

Guest Expert:  Dr. Kathryn Tristan, Washington University in St. Louis School of Medicine
