The function of the immune system is to protect your body from infections and illnesses. Your immune system works to identify pathogens and tumor cells that could cause disease and to eliminate them from your system. Your body's immune system has an incredibly difficult task in doing this because these pathogens and bad cells are sneaky: they can redesign themselves and adapt to changes your body makes to get rid of them. answer by Diamond Madison
