Answers
Answer:
(a) When your body temperature rises because of an infection, it's called a fever. Fevers are caused by chemicals called pyrogens flowing in the bloodstream. ... One purpose of a fever is thought to be to raise the body's temperature enough to kill off certain bacteria and viruses sensitive to temperature changes.
(b) We feel cold because technically we are colder than our body's new set point. The body works to generate heat to warm itself by contracting and relaxing muscles — hence the shivering, or chills.
(c) When skin feels hot to the touch, it often means that the body's temperature is hotter than normal. This can happen due to an infection or an illness, but it can also be caused by an environmental situation that increases body temperature.
