Question
Chapter 15, Problem 30RA
Summary Introduction
To review:
The mechanism by which the innate immune system recognizes pathogens and responds to them.
Introduction:
The immune system provides protection against the deleterious effects of various pathogens. The body mainly has two types of immunity, namely innate immunity and acquired immunity. Innate immunity is present since birth and serves as the first line of defense mechanism. Acquired immunity is generated throughout the lifetime of an individual and it is the second line of defense.
