How does the immune system work to prevent pathogens from causing disease in the body?

Not exactly, at least not the immune system most know.
In the acquired immune system, a disease enters your body and starts making you feel ill. Your immune system can now destroy this disease because it is in you and it has sensed it. Sometimes diseases are sensed so quickly and the body is already ready for it (due to memory b-cells)
that you never feel it. This often happens with the chicken poxs.
However the innate immune system can completely prevent certain diseases. Your innate immune system is made up of your skin, your digestive track (primarily the stomach and its acid), and mucus membranes (like inside your nose and lungs). Those systems can block diseases and send them away before they fully enter the body (cool facts, the space in your lungs and your digestive system are not considered "inside the body" - that's right, there is basically a hole going right through your person.)

If we are surround by pathogens why don't we die of disease?
Because our bodies have evolved to defend ourselves from these pathogens. We have an "immune system".
Which is your body and rsquos ability to destroy pathogens that it has previously encountered before these pathogens can cause disease?
Immunity.
What is a small dose of weakened pathogens that make you immune to disease called?
a vaccine
What disease causes the body to attack pathogens and its normal cells?
Auto-immune
The body's most specific defense mechanism is?
Natural immunity, such as skin. For example, the skin is a physical barrier that keeps out pathogens (disease causing factors).
Which are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells?
Antibodies are special molecules of protein produced by the immune system that match parts of pathogens and prevent them from infecting cells.
What does the immune system normally do?
fight against illnesses
How do viral infections in animals cause disease?
by a weakend immune system letting pathogens into the body.
What is active vs passive immunity?
Active immunity occurs when an individual is exposed to the disease causing organism, and the immune system produces antibodies to counteract the disease. Future exposure to the same pathogens will stimulate a rapid response from the immune system to produce antibodies. Passive immunity occurs when an individual receives antibodies instead of inducing the immune system to produce antibodies.
What is the function of the immune system?
The function of the immune system is to protect your body from infection by pathogens and foreign invaders, or what the body perceives as invading "germs". Your immune system works to identify pathogens and sometimes other unrecognized cells, like tumor cells, that could cause disease and then to eliminate them from your system. Your body's immune system has an incredibly difficult task in this because some of these pathogens can be "sneaky": they can redesign (mutate) themselves to trick the immune system into misidentifying them as harmless cells rather than appropriately treating them as foreign invaders.
Sentence with immune?
The immune system identifies, remembers, attacks and destroys disease-causing invaders or infected cells.
What is a harmless version of a disease causing microbe that stimulate a person's immune system?
A vaccine.
