Question

Quizplus · Accepted Answer

Pyrogens are substances that induce fever in the body. They act on the hypothalamus, which is the part of the brain that regulates body temperature, causing it to increase the body temperature. This increase in temperature helps to fight off infections and other inflammatory reactions by stimulating the immune system. Unlike what options A, C, D, and E suggest, pyrogens do not decrease body temperature or cause vasodilation or vasoconstriction.
