a. recognize self from nonself. U/ U/ U/


b. defend the body against nonself.U/ U/ U/ U/


c. amplify specific functions. U/ U/


d. Both A and B. U/ U/ U/




ANS: D U /


The function of the immune system is to recognize self from nonself and defend the body a
U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/ U/


gainst nonself. Such a system is necessary for survival. The immune system also has nons

pecific effector mechanisms that usually amplify the specific functions. Nonspecific compo

The desirable consequences of immunity include natural resistance, recovery, and acquired re
