Have a science project and need answers quick! So as soon as your 2nd line of defense is activated do you get sick, or are you sick when the pathogen is attacking your 1st line of defense?
Thanks!

Well the first line of defense can be your skin, or nose or mouth. Once something gets past one of those, you still that your white blood cells and immune system to defend.
So no, getting past the 1st line of defense doesn't mean you'll get sick
