How the Body Defends Against Pathogens… • Draw the outline of a body (NOT a stickman!) • Label how the body keeps pathogens out (e. g. ear wax)

How the Immune System Defends Against Pathogens… • What can you remember about the immune system and how it works? (Hint: what three processes do white blood cells do? )
