Your body recognizes bacteria, viruses, and other substances that seem strange and hazardous and protects itself against them using the immune response.
Which of the following distinguishes between innate and adaptive immunity?
The first line of defense the body has against infections is innate immunity. It does not distinguish between different pathogen kinds since it is generic and non-specific. One sort of immunity that develops as we are exposed to illnesses or receive vaccinations is adaptive immunity.
