Final answer:
The specific term for toxins that microbes produce to kill WBCs is not provided, but microbes employ immune evasion to protect themselves from WBCs' immune responses. Phagocytes destroy bacteria through phagocytosis, and macrophages are both phagocytic and inflammatory.
Step-by-step explanation:
The term that describes toxins produced by microbes that are capable of killing white blood cells (WBCs) is not listed in the options provided. However, the mechanism that microbes employ to protect themselves from the immune responses of WBCs, including the production of such toxins, is termed immune evasion. Microbes use various strategies for immune evasion, such as producing capsules to inhibit phagocytosis, producing proteases that break down host antibodies, and avoiding detection by modifying surface antigens.
From the question's context, we can assume that the correct answer should relate to immune evasion (d). Moreover, the method by which a phagocyte destroys a bacterium it has ingested is through the process of phagocytosis, where the pathogen is engulfed and digested within a phagolysosome.
Macrophages (option b from the Review Questions) are a type of white blood cell that is both phagocytic and capable of producing chemicals that promote inflammation, thereby playing an essential role in both innate and adaptive immune responses.
