It is well known that gravity influences the physiology of the lung and thereby affects the intrapulmonary localization of disease processes. Less well known are the anatomic and physiologic differences in the axial or cross-sectional plane, which also affect the distribution of disease. Physiologic gradients in ventilation, perfusion, and lymph flow and stresses in the lung are present in the axial plane. Anatomic difference in branching patterns, interstitial design, and development of the… CONTINUE READING
