The main, or central, idea of the passage is Fevers are useful because they help the body fight infections. How does the detail in bold develop the main idea?Fevers 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.It explains the function of lymphocytes in great detail.It describes one manner in which fevers fight infections.It points out a weakness of the fever response.Submit

Fill in the blank question.A fever, an increase in body temperature, often accompanies an infection. The body responds in such a manner to the rates of defensive reactions that kill bacteria.

While all effects of fever are not entirely understood, some studies have suggested various reasons as to why especially low-grade fevers may be beneficial. Which of the following would not be a function of fever?ANSWERFever promotes tissue repair.Fever works by limiting the production of prostaglandins in the hypothalamus.Fever enhances the antiviral effects of interferons.Fever increases phagocyte efficiency.

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.
