Study Notes
Innate Immunity
- The main characteristic of innate immunity is that it provides immediate, non-specific defense against infection.
Biological Barriers
- skin and mucous membranes are examples of biological barriers in innate immunity.
Physiological Barriers
- The low pH of the stomach is an example of a physiological barrier in the second line of defense.
Inflammatory Barrier
- The inflammatory barrier in the second line of defense is induced by the presence of pathogen-associated molecular patterns (PAMPs) or damage-associated molecular patterns (DAMPs).
Cells of Innate Immunity
- Cells that are part of the innate immune system as the second line of defense include neutrophils and macrophages.
