Keywords

anthropophysiological approach, upright posture, gravitation gradient of lungs ventilation and perfusion, clinostatics, orthostatics

Abstarct

The authors considered gravitation factor influence on respiratory system of health men; it showed in organ morphofunctional heterogeneity, lung air distribution irregularity and in gradient of negative pleural pressure between apex pulmonis and basis pulmonis. The “conception of three functional lung zones” which was formulated on the base of influence of alveolar pressure on pressure and blood flow in pulmonary circulation was thoroughly analyzed. Due regard for gravitation gradient in ventilation and perfusion of lungs was necessary both for working-out of therapeutic tactics and for prevention in the most part of diseases.
