Think about how the immune system is organized, and how the various components functions. You will be provided with certain components of the immune system. Classify whether that component, as described, provides a 'non-specific' defense, 'provides specific defense against certain classes of microbes', or provides specific defense to a single microbe. Finally, the 4th choice will be an option to state that a particular component of the immune system, as described, provides 'no protection', by itself. Question 31 options: The...
