Source: Vovchyn Taras/Getty Images OpenStax Anatomy and Physiology When the environment is not thermoneutral, the body uses four mechanisms of heat exchange to maintain homeostasis: conduction, convection, radiation, and evaporation. Each of these mechanisms relies on the property of heat to flow from a higher concentration to a lower concentration; therefore, each of the mechanisms … Continue reading Mechanisms of Heat Exchange
Source: OpenStax Anatomy and Physiology OpenStax Anatomy and Physiology The body tightly regulates the body temperature through a process called thermoregulation, in which the body can maintain its temperature within certain boundaries, even when the surrounding temperature is very different. The core temperature of the body remains steady at around 36.5–37.5 °C (or 97.7–99.5 °F). … Continue reading Energy and Heat Balance
