• The study examines respiratory parameters in healthy young males from Western Siberia. The correlations between the parameters are analyzed and the functional structure of the respiratory system in the summer and in the winter is identified. It was discovered that different regulatory programs operate depending on the temperature of inhaled air. The study shows that the changes in the oxygen request of the body in the summer are achieved through the changes in the volume of pulmonary ventilation ("ventilation" or "summer program"). In the winter, when maintaining the level of energy processes in the body is in conflict with maintaining thermal homeostasis in the respiratory regions of the lungs, pulmonary ventilation becomes limited and the number of functioning lung units is reduced. At the same time, for providing compensation, lung diffusion capacity increases ("diffusion" or "winter program"). This means that the functioning of the apparatus of external respiration is optimized in the winter.
