Describe three effector actions of innate immunity.
Nagamalla R.
Innate immunity: a. First line defenses: List three physical and three chemical defenses and describe how they defend your tissues from invasion by pathogens. b. Second line defenses: Name three ways your innate immune system responds to invasion by pathogens and how they help fight infection. 2. Adaptive immunity: Humoral a. Describe how B cells are activated. b. List and describe the how antibodies help clear an infection. 3. Adaptive immunity: Cell mediated a. Describe how T cells are activated. b. Describe how T cells help clear an infection.
