The article discusses the morphology of volar cutaneous blood vessels of man to countercurrent thermal flow in thermal regulation. The voral dermal circulatory system is arranged in a characteristic pattern which assists thermal regulation by the skin. This characteristic vascular architectural plan is described and certain functional structural relationships are emphasized. These relationships are believed to regulate the time course of the rate of flow of blood into the superficial capillaries and thermal exchange at the epidermal surface. The three-dimensional arrangement of the courageous blood vessels and their quantitative inter-relationships are described. During studies of the volar skin of man, the spatial orientation of the blood vessels was noted to be ideal for regulation of thermal exchange between the blood and the environment. It is evident from the spatial orientation of the blood flowing under the skin that when man is exposed to a cold environment, countercurrent flow will facilitate the conservation of body heat.
