AB The  immune  system  protects  the  body  from  invading  pathogens  and  has  an  amazing  ability  to  evolve  and  adapt  based  upon  environmental  exposure.  The  immune  system  is  designed  to  attack  and  destroy  foreign  antigens/pathogens;  however,  the  immune  system  must  be  able  to  distinguish  self  from  nonself.  Failure  to  differentiate  self  from  nonself  may  lead  to  autoimmune  diseases1  (see  Table  11-1  for  a  list  of  autoimmune  diseases).  The  immune  system  includes  two  functional  divisions:  (1)  innate  or  nonspecific  and  (2)  adaptive  or  specific.2,  3  The  body  uses  the  innate  and  adaptive  immune  responses  to  kill  foreign  pathogens.  The  greatest  differences  between  the  responses  are  in  specificity  and  memory.  The  adaptive  immune  response  can  evolve  with  each  subsequent  infection,  whereas  the  innate  immune  response  stays  the  same  with  each  infection.2,  3  Awareness  of  immune  systems  components  and  consequences  of  disrupting  homeostasis  must  be  understood  in  order  to  appropriately  dose,  administer,  and  monitor  effects  of  medications  given  to  manipulate  immune  responses.
