In the horizontal position (supine and lateral), in the upright position (head up and head down) and during change of the cat body position in space, quantitative responses of regional blood volume and blood flow in the lungs (ml/100 cm3) revealed presence of the gradient in the gravitation direction. Blood volume and blood flow of different lung portions changed qualitatively and quantitatively in different ways. These changes occurred only in the direction producing the equality of regional hydrostatical and hemodynamic loads in the lungs at either horizontal level.
在水平位（仰卧位和侧卧位）、直立位（头高位和头低位）以及猫在空间中身体位置改变时，肺部区域血容量和血流的定量反应（毫升/100立方厘米）显示在重力方向存在梯度。不同肺段的血容量和血流在质和量上以不同方式发生变化。这些变化仅发生在使肺部不同水平区域的流体静力学和血液动力学负荷相等的方向上。
