Summary The lung, save for the larger trunks of the bronchial tree and vascular bed, is regarded as a three-component medium (air, blood, tissue). The correlation between the air and the tissue + blood structure is preset on the assumption that the air contained in the alveoli presents closely arranged spheres of identical size, surrounded by a conducting medium (blood + tissue) with summary specific electroconductance determined from the law of parallel connection of these two components. The coefficient depending on the structural and volumetric correlations within the blood + tissue system has been found empirically. A simple formula is given for calculation of the air content in the unit volume of the organ. Experiments on isolated pulmonary lobes have shown that in the majority of cases there is a satisfactory coincidence between the results of determination of the air amount by the direct method and that suggested here.
