When a pathogen evades the
bodys nonspecific immune defenses, it then encounters the
specific immune response.
The cellular and noncellular
components of the specific immune system work together to destroy
foreign invaders. Because it is both specific and diverse, our
immune system is able to respond to millions of different pathogens.
In this Lesson, we'll introduce
the components of the specific immune response and look at their
specific roles in fighting infections. Then we'll look at what
happens when the immune system doesn't work properly.
