Before moving on ask yourself if you've met the Learning Targets for this week:

Describe the different pathogens and how they are transferred Describe how vaccines are used in prevention and treatment of viral diseases Describe the body's innate physical and chemical defenses Explain the inflammatory response Explain adaptive immunity Describe cell-mediated immune response and humoral immune response Describe immune tolerance Describe hypersensitivity Define autoimmunity

If not take the time to review the ones you are uncertain of, and let your teacher know if you need more help on any of these.
