Body heat regulation is a constant within the human body, and regulation can take place by several means. In which way does the body regulate itself by means of heat loss?
  1. Convection
  2. Conduction
  3. Respiration
  4. All of the above.
Explanation
Answer: D - The body regulates itself by means of heat loss by convection, conduction, and respiration. Convection is the body heat lost to surrounding air. Conduction is body heat loss to surrounding objects through direct physical contact. Respiration is body heat loss through the process of breathing. The body also loses heat through radiation and evaporation; however, these are not considered a “loss” per se. Radiation is the transfer of heat from the surface of one object to another without physical contact. Evaporation is when body heat causes perspiration; heat is lost from the surface of the body when water is changed from liquid to vapor.
