This paper presents arguments for these conclusions Under physiological conditions automatic and adaptable activity of respiratory functional system is provided by elaborate complex of reflex reactions of different levels. Under conditions of changed gaseous medium against the background of developing hypoxia predominantly value acquires direct effect of products of partial oxidation on cerebral cortex of brain, and then on the medulla oblongata. Under the conditions of hypoxia receptor zones in the tissues of brain, including in the venous sinuses and bulbus venae jungularis acquire special importance. They are the first receptors to receive the effect of the products of partial oxidation, which are generated in the cortex, and because of them the preferential oxygen supply to the cells of cortex, and because of them the preferential oxygen supply to the cells of cortex occurs. With changed gaseous medium first of all is disturbed activity of cortex, which ensures formation of functionally mobile constellations of nerve centers, which integrate the adaptation of the functional systems to varied conditions of vital activity.
