Answer:
When the body has a fever, the body systems may communicate differently in order to fight off infection. The body’s immune system may kick into gear, releasing cytokines and other immune mediators to fight off the infection. The body’s endocrine system may release hormones such as adrenaline, cortisol, and others to help fight the infection. The nervous system may become more active as the body works to regulate its temperature, causing shivering or sweating. The cardiovascular system may also become more active, pumping more blood to the skin surface to cool the body and to the organs where infection-fighting cells can be more easily delivered.
