Multiple Choice QuestionAn infection is often accompanied by an increase in body temperature, or fever. What is the kinetic role of fever in fighting infection?Multiple choice question.Increased body temperature inhibits the biochemical reactions of bacteria.An increase in body temperature alerts the patient to the presence of the infection.Increased body temperature increases the rates of the body's defensive reactions.
Solution
The correct answer is: Increased body temperature increases the rates of the body's defensive reactions.
Here's why:
-
Increased body temperature inhibits the biochemical reactions of bacteria: While it's true that extreme temperatures can inhibit bacterial growth, the slight increase in body temperature during a fever is not enough to significantly impact bacteria.
-
An increase in body temperature alerts the patient to the presence of the infection: While a fever can be a sign of an infection, it's not its primary purpose. The body doesn't increase its temperature to alert the person of an infection, but rather as a response to fight off the infection.
-
Increased body temperature increases the rates of the body's defensive reactions: This is the correct answer. A fever is part of the body's defense mechanism against infection. The increase in body temperature can speed up the body's metabolic rate and the activity of cells, including those involved in the immune response. This can help the body fight off an infection more effectively.

Read the passage.How Fevers HelpFevers can be uncomfortable, but the upside is that they are evidence of the body's attempt to heal. When a person develops an infection, a section of the brain called the hypothalamus recognizes a threat. The hypothalamus responds by increasing the body's temperature. Since both viruses and bacteria are temperature sensitive, this environment helps prevent them from multiplying. In addition, scientists have found evidence that fevers may increase the number of certain lymphocytes—white blood cells that are part of the immune system. Increased lymphocytes make the body more effective in destroying infected cells. Of course, this doesn't mean that high fevers don't warrant medical treatment. In fact, another reason that fevers are beneficial is that they serve as warning signs, indicating that something is amiss.What is the main, or central, idea of the passage?Fevers are useful because they help the body fight infections.Fevers are useful because they increase the body's lymphocytes.The hypothalamus responds to infections by raising the body's temperature.Submit
