Infection begins. And as soon as infection begins the innate immune system uses nonspecific defense mechanisms such as the process of inflammation. And what inflammation does is it ultimately localizes our infection to that specific region. It calls upon macrophages and oleukocytes that essentially engulf the pathogens as well as our infected cells. Now, while this process is taking place and while the innate immune system is preventing the spreading of this pathogen of this infection the adaptive immune system also known as the quiet immune system the other part of our immune system begins to mobilize itself. It begins to gear up to basically help fight that infection.
