Transport of heat through the skin

Abstract

The transport of heat through the skin of the human body has been investigated in the paper. The analysis of cytoarchiterture of this region was done, a model of vascular stream of the skin was built where the transient microregion typical for its different tissues was separated. A mathematical model taking part both convective and conductive heat transport was reproduced for this microregion. There was no heat transfer through the blood but only conductive heat transport was shown to be in the superficial skin tissue strates having blood current. In the norm, there was convective heat transport preferably in the deeper skin strates of the hypoderm where arterials and veins of more than 100 and 300 um in diameter were lying. The organism was revealed to able to increase or decrease the skin region where there was only convective or conductive heat transport by means of changing the blood stream. Therefore, the organism is able to change the size of peripheral tissue where there is only convective or only conductive heat transfer according to physiological necessity.
