Innate immunity is the first line of defense. It’s a rapid response compared to adaptive immunity which can take days.
“These cells signal the occurrence of injury or infection and initiate a cascade of inflammatory processes that help contain an infection and promote healing and recovery.” (Slavich)
Adaptive Immunity
Adaptive immunity is created in response to exposure of a foreign body. It can work without innate immunity.
The function of adaptive immune responses is to destroy invading pathogens and any toxic molecules they produce. (Alberts B, Johnson A, Lewis J, et al, 2002).
