What is the function of the immune system?

Answer 1

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.
