immune system - CORRECT ANSWER-complex body defines system-
protects body against bacteria, viruses, toxins and parasites
innate system - CORRECT ANSWER--present at birth
-not antigen specific
-present at all times
-does not improve with
repeated exposure to infectious agent
adaptive immune system - CORRECT ANSWER--develops throughout
life
-antigen specific
,-lag time between infection and response
-memory develops- provides lifelong immunity to reinfection
