Very few pathogens can survive the acid environment of the stomach. The acids could burn a hole in a rug. The pH is 1.5 to 3.5.

how does residental normal flora protect the body against pathogens
Cilia protect your body from pathogens up to a certain extent. The cilia in your lungs prevent dust particles and other such particles you breathe from entering your lungs by trapping them and sweeping them away. The cilia located on the cell membrane prevents certain substances from entering the selectively permeable cell membrane through that same manner. However, if you get a cut or something, cilia are not really going to protect pathogens from entering your body from that cut.
Symptoms of bloodborne pathogens include stomach problems, flu like symptoms, fatigue, and weight loss. HIV and malaria are bloodborne pathogens.
it is all to do with a buffer system in the stomach! the body has many of these systems! its to ensure homostasis! the mucus in the walls of the stomach protect from selfdigestion! the stomach contains hcl which is concentrated! this is what keeps the pH low!
Yes, there are examples of pathogens attacking human tissue. An example is Helicobacter pylori forming ulcers in your stomach.

The pores on your skin help to prevent harmful pathogens from entering. Pathogens cause disease, infection and Cancer. By keeping these pathogens out, this is how pores protect you.
Immune system,

they attack it
They don't defend pathogens. They defend *against*pathogens. They poison them, they burn them with ozone / hydrogen peroxide / sodium hypochlorite / chorine dioxide, and then they eat them whole if necessary.
Your body is really a possible large dinner table for pathogens that are found everywhere. You need as many defenses as you have to fend them off.
Viral infections and cancerous cells
cilia prevents the entrance into the body by pathogen by constantly beat toward the outside of the body. If it is in your throat it will beat it toward your stomach so stomach acid can destroy the pathogen.
The hydrochloric acid in the stomach helps protect against disease because it kills many microorganisms and toxins in food.
Serves as a physical barrier to keep pathogens out.
Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them. Mucous is a physical barrier against pathogens. It acts to trap pathogens to prevent them from entering the body any farther.
