Morphometric data of the pulmonary veins in the cat right lung are presented. Silicone elastomer casts of the right lungs of five cats were made, measured, counted, and analyzed. The Strahler system is used to describe the branching pattern of the vascular tree. These data are needed for the physicomathematical approach to pulmonary circulation. For all the pulmonary blood vessels lying between the left atrium and the capillary beds, there are a total of 10 orders of vessels in the right upper lobe, 9 orders of vessels in the right middle lobe, and 11 orders of vessels in the right lower lobe. The ratios of the diameters, lengths, and the number of branches in successive orders of vessels are called the diameter, length, and branching ratios, respectively. For the cat pulmonary venous tree, the average branching ratio is 3.521, the average diameter ratio is 1.727, and the average length ratio is 2.402 for vessels of orders 1-3 and 1.532 for vessels of orders 4-10.
本文展示了猫右肺肺静脉的形态测量数据。制作了五只猫右肺的硅橡胶弹性体铸型，并进行了测量、计数和分析。采用斯特拉勒系统来描述血管树的分支模式。这些数据是肺循环物理数学方法所必需的。对于位于左心房和毛细血管床之间的所有肺血管，右上叶共有10级血管，右中叶有9级血管，右下叶有11级血管。连续各级血管的直径、长度和分支数量之比分别称为直径比、长度比和分支比。对于猫的肺静脉树，1 - 3级血管的平均分支比为3.521，平均直径比为1.727，平均长度比为2.402；4 - 10级血管的平均长度比为1.532。
