Why does a warm-blooded organism rapidly regulates body temperature in the thermoneutral zone

Abstract

In work, the analysis of thermal homeostasis in the human body and homoiotherm animals. It is shown that the temperature in the internal tissues of the body (the nucleus of the body) is high and relatively consistent because it is maintained via heat transfer through the blood flow. The presence in peripheral tissues (the body shell) is mainly due to conductive heat transfer (due to temperature gradients at various points of the tissues). Thermal homeostasis occurs when the temperature of the medium fluctuates within the thermoneutral zone in the internal tissues of the body, primarily due to changes in the size of the nucleus and shell rather than changes in heat output to the external environment or heat production. Owing to this mechanism of heat transfer in the tissues, a rapid thermal homeostasis of the internal tissues of the body is carried out when the temperature of the medium changes within the thermoneutral zone.
