During a Major Infection, You Get a High Fever Because

Question

During a major infection, you get a high fever because
A)the bacteria in your body produce chemicals that cause the brain to raise your temperature to make the environment more amenable to bacterial growth.
B)your immune system signals the brain to raise body temperature to limit bacterial growth and speed up phagocytosis.
C)pathogens damage tissues throughout your body, causing an extreme inflammatory response.
D)your low energy levels prevent the brain from maintaining the negative feedback loop that controls body temperature.

Accepted Answer

When your body is infected, your immune system releases chemicals called cytokines, which signal the hypothalamus in your brain to raise your body temperature. This elevated temperature, or fever, helps to limit bacterial growth and speed up the activity of immune cells. Fever can also make the body less hospitable to certain pathogens.
