Innate resistance natural barriers | physical, mechanical and chemical |
Innate resistance innate inflammation | first line of defense is breached |
Adaptive immunity | is an acquired or specific immunity |
Adaptive immunity is either | active or passive |
Active natural immunity | develops after exposure to antigen |
active artificial immunity | develops after administration of vaccine. |
Passive natural immunity | maternal antibodies cross placenta in breast milk |
Passive artificial immunity | antibodie adminstered to combat infection. |
