It is carried in air droplets so enters through the airway and then into the lungs where it thrives on warm, damp environment.
Active acquired immunity occurs when you get an infection by a pathogen (bacteria, virus) and your body responds and removes the pathogen and also your body makes "memory" cells. These cell remember this pathogen and when it enters your body again you remove it immediately. You are now immune to it. You usually don't notice this.
The inflammatory response is the body's response to infection. After a pathogen enters the body and creates an infection, leukocytes rush to cite to kill off the bacteria. Inflammation results because of the puss that the body secretes to combat the bacteria. After the intruder is eliminated the body tries to heal the passage through which the pathogen entered, by closing it off and healing the skin.
Prions are the easiest way to answer this. Prions are like mis-folded proteins that cannot reproduce. When a prion enters a cell, it interacts with the normal protein and transforms it into the prion's version. By transmissible pathogen it means that the forgein body is able to be passed along.
No white blood cells are not pathogens, they protect the human body from pathogens.
Technıcally, a pathogen ıs anythıng that trıes to attack your body, so that bacterıa ıs the flesh-eatıng pathogen.

It is called a pathogen! it carries the bacteria fugus disease or whatever else into the body!
Yes, contagious diseases are infections. Infections are occur when a pathogen (germ) enters the body and reproduces.
Respiratory tract
The pathogen tries to infect the body. The defense mechanism of the body resists the entry of the pathogen. If pathogen succeeds the infection is established and the body becomes sick.
A very broad answer to a very broad question... A "pathogen" as defined by a dictionary would be, "any disease-producing agent, esp. a virus, bacterium, or other microorganism." First- a "pathogen" in drinking water will cause nothing unless someone or something drinks the water or if the "pathogen" enters the body/host by some other means... Second- even once the "pathogen" enters the body it may still cause nothing, as the quantity of the "pathogen" must be sufficient to cause the would be disease... Third- because a "pathogen" could be any one of millions of things, what disease would be caused by your hypothetical "pathogen in the drinking water" would depend entirely on what it is... You should seriously consider being more specific about your question. If you are interested in a specific pathogen and the associated disease, please try again.

During subsequent exposures to the same pathogen, the immune system is able to respond rapidly and activity reaches higher levels. The secondary immune responses can usually prevent disease, because the pathogen is detected, attacked and destroyed before symptoms appear.
Tuberculosis (TB) is caused by an airborne pathogen but is also carried in the saliva. Infected persons can spread the pathogen by breathing, coughing, kissing, or by sharing drinking cups / straws with saliva on them. Infected persons wear a mask until treatment has reduced the number of viruses found (the viral load). A recent case on an overseas flight meant all passengers needed screened for TB and treated on a "just in case" basis because TB is highly contagious!
