A mathematical model for the thermoregulation in the dermal layers of the human body is proposed.The skin is composed mainly of three layers-epidermis,dermis and subcutaneous tissues.The relative constancy of the body temperature is remarkable because there is a continuous exchange of heat with the external environment as well as within the different compartments of the body.A model describes the distribution of dermal temperature as a function of internal and external parameters,such as temperature of the incoming arterial blood,blood flow,ambient temperature,and heat exchange with the environment.It is shown that substantial changes in human dermal temperature can be accomplished only through changes in the temperature of the incoming arterial blood or substantial suppression of blood flow.Other parameters can lead only to temperature changes near the skin surface.
A mathematical model for the thermoregulation in the dermal layers of the human body is proposed. The skin is composed mainly of three layers-epidermis, dermis and subcutaneous tissues. The relative constancy of the body temperature is remarkable because there is a continuous exchange of heat with the external environment as well as within the different compartments of the body. A model describing the distribution of dermal temperature as a function of internal and external parameters, such as temperature of the incoming arterial blood, blood flow, ambient temperature, and heat exchange with the environment. It is shown that substantial changes in human dermal temperature can be accomplished only through changes in the temperature of the incoming arterial blood or substantial suppression of blood flow.
