[Morphofunctional features of the microcirculatory bed of the skin in students from different climatogeographic zones].

By means of the vital microscopy method length, diameter, stipulated area of the longitudinal section have been studied in the nail torus capillaries of students from different regions of the world depending on the climatogeographic zones. The value of the structural parameters in the skin capillaries, which characterize their heat exchange surface, directly, depends on temperature factors of the environment. There is an increase of the heat exchange surface in the capillaris of the person-inhabitants beginning from the moderate towards the subtropical, tropical and subequatorial zone. The exception make the students from the equatorial zone: the structure parameters of their capillaries are less than in the persons from the subequatorial and even from the tropical zones. This is connected with the fact that the equatorial zone is characterized with some extermal amount of heat and moisture.
