how does fever indicate that your bodys immune system is doing its job?\no fever increases red blood cell production.\no fever raises the bodys temperature to destroy harmful substances.\no fever triggers inflammation.\no fever causes the secretion of hormones that fight harmful substances.
Answer
Brief Explanations:
Fever is a response where the body - temperature rises to inhibit the growth and activity of pathogens (harmful substances) and enhance the immune - system's function. Red blood cell production is not directly increased by fever. Inflammation is a separate immune response not directly triggered by fever in the way described. Hormone secretion related to fighting substances is not the main way fever indicates immune function.
Answer:
Fever raises the body's temperature to destroy harmful substances.
