IMMUNOLOGY

Detailed explanation-1: -The innate responses call the adaptive immune responses into play, and both work together to eliminate the pathogens (Figure 24-1). Unlike innate immune responses, the adaptive responses are highly specific to the particular pathogen that induced them. They can also provide long-lasting protection.

Detailed explanation-2: -The immune system can be classified into two subsystems: the innate and adaptive immune systems. In general, innate immunity is considered a nonspecific response, whereas the adaptive immune system is thought of as being very specific.

Detailed explanation-3: -The adaptive immune system, also called acquired immunity, uses specific antigens to strategically mount an immune response.
