Taller 10. Sistema Inmune (cap 42) 1. 42.1 Animals have nonspecific and specific defenses against pathogens. Both kinds of mechanism are based on the ability to differentiate self from nonself. Nonspecific defenses target a broad range of molecules and organisms, while specific defenses target specific configurations of atoms on molecules. a. List the differences between specific and nonspecific defenses. See p. 874 b. What are the two classes of white blood cells, and how do they function in vertebrate defense systems? See p. 875 and Figure 42.2 2. 42.2. Nonspecific defenses are the first line of defense against pathogens. These include physical barriers such as the skin; defensive proteins; and coordinated responses such as inflammation. a. How do complement proteins and interferons defend the body against microbes? See p. 578 b. Describe the inflammation response. See pp. 878–879 and Figure 42.3 3. 42.3 The specific immune system reacts against nonself or altered self molecules call
