Immune System Lines of Defense:
The immune system includes three lines of defense against foreign invaders: physical and chemical barriers, nonspecific resistance, and specific resistance.
The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity.
The second line of defense is nonspecific resistance, which also is considered a function of innate immunity. The third line of defense is specific resistance, which is considered a function of acquired immunity.
Innate immunity involves nonspecific immune defense mechanisms that activate immediately or within hours of an antigen’s invasion of the body. Innate immunity is present at birth. Innate immunity activates when the immune system recognizes chemical properties of the antigens.
Acquired immunity, also referred to as adaptive or specific immunity, is not present at birth but is learned. The immune system encounters antigens and the acquired immunity’s components learn how to attack each antigen and develop a memory for it. Specific immunity tailors attacks to specific antigens because it learns, adapts, and remembers them.
