On the absorption capacity of the nasal mucosa in different types of breathing

Numerous works by Prof. Tsytovich's school, Prof. Viktorov's physiological laboratory and Prof. Trutnev's clinic with the elimination of dyestuffs from the body during different types of breathing have shown that in oral and tracheal breathing dyestuffs are delayed much longer and are distributed in the tissues differently than in the nasal breathing. This is explained by the fact that the movement of the intra-tissue fluid washing the tissue cells is slower with mouth breathing. The latter affects the nutrition of the cells, their metabolism, which in turn is accompanied by a change in their normal state, the constitution of each cell individually and the body as a whole.
