Multiple Choice

Fever can have positive effects on the process of fighting an infection. Which of these answers is not a positive effect fever can have during an infection?

High body temperatures inhibiting the growth of many pathogenic bacteria.

High body temperatures increase the enzymatic reactions associated with the immune system.

High body temperatures enhance the inflammatory response and release of inflammatory signals.

High body temperatures constrict the blood vessels ensuring the infection does not spread throughout the body.

Verified step by step guidance

Understand the role of fever in the immune response: Fever is a common physiological response to infection, characterized by an increase in body temperature. It is part of the body's defense mechanism against pathogens.

Evaluate the positive effects of fever: High body temperatures can inhibit the growth of many pathogenic bacteria, increase enzymatic reactions associated with the immune system, and enhance the inflammatory response and release of inflammatory signals.

Consider the physiological effects of high body temperature: Fever can lead to vasodilation, which increases blood flow to infected areas, aiding the immune response. It does not typically cause vasoconstriction, which would reduce blood flow.

Identify the incorrect statement: The statement 'High body temperatures constrict the blood vessels ensuring the infection does not spread throughout the body' is not a positive effect of fever. Vasoconstriction is not a typical response to fever and would not aid in fighting an infection.

Conclude the analysis: Recognize that the incorrect statement is based on a misunderstanding of fever's role in the immune response. Fever generally promotes processes that help fight infection rather than constricting blood vessels.
