What is the difference between acquired and innate immunity?

Innate immunity is the inborn resistance against infections that an individual possesses right from the birth, due to his genetic or constitutional markup. Acquired immunity is the resistance against infecting foreign substance that an individual acquires or adapts during the course of life.
