What barriers does the human body have to prevent pathogens entering?
The most obvious is the physical barrier - one's skin. The body also has enzymes such as lysozyme and defensins, which are secreted on the exterior, and kill bacteria. The acid in the stomach also kills most pathogens, and the lining of the intestines prevents many pathogens from entering the blood stream from the gut. In the blood, there are immune cells which mark and attack invading pathogens too. It's therefore astonishing that pathogens have evolved mechanisms to evade or counter all of these defences.
