Lori Herrington. Chaparral High School. What is immunology?. Very simply, it is the study of our body’s defense against infection and disease.. Even though we are constantly bombarded by microorganisms, we rarely become sick. Why?. Kyle Murar. 5/5/2015. Period 4. What is Immunology?. Immunology is the study of the immune systems of all organisms.. Immunologists not only study the human immune system, but the immune systems organisms ranging from archaea bacteria to zebras..
