[Extracapillary oxygenation of blood in the lungs].
The transition of oxygen from ventilated alveoli into the non-capillary vessels of minor circulation was revealed in cats by microoxygenometry and polarogramphic evaluation of the blood. The O2 diffusion from alveoli into the blood of arteriolas and small arteries occurs in the lungs, as well as the O2 permeation through the walls of the lung venules and small veins. Thereupon, the high oxygenation of the blood occurs yet before the capillaries of the small circulation.
