B) Interferon activity
C) Leukotriene activity
D) Phagocytosis


C
Feedback:
The leukotrienes (autocoids activated through the kinin system) affect the brain to induce slow-wave sleep, believed to be an important energy conservation measure for fighting the invader. They also cause myalgia and arthralgia (muscle and joint pain)—common signs and symptoms of various inflammatory diseases, which also cause reduced activity and save energy. Interferons are released in response to viral infection. Phagocytosis destroys engulfed foreign material in the body. Bacterial toxins cause local reactions unless the infection is intense and the bacteria enter the bloodstream.
