Innate immunity provides the first line of defense and responds rapidly to protect the body against infection. Specific immunity involves producing antibodies against a pathogen to destroy it. Another very important role of this system is to keep a record of each infectious particle or microbe against which it has defeated to protect the body to recognize and kill the microbe rapidly if it enters the body later.
