摘要

直立体位时，通气和灌注均由肺顶向肺底增加。以前认为这是由于重力的影响(所谓的引力模型)，但现在认为肺动脉和细支气管之间的结构相似性起了作用(见第15章)。

Ventilation–Perfusion Zones in the Lung

In the upright position, ventilation and perfusion both increase from the top to the bottom of the lung. This was previously attributed to the effect of gravity (the so-called gravitational model), but it is now thought that structural similarities between the pulmonary arteries and bronchioles contribute (see Chapter 15).
