Morphometic data of the pulmonary artery in the cat's right lung are presented. Silicone elastomer casts of cat's right lung were made, and measured, counted and analyzed. The Strahler system is used to describe the branching pattern of the arterial vascular tree. These data are needed for any quantitative approach to the study of the pulmonary circulation. For all the pulmonary blood vessels of the cat lying between the main pulmonary artery 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 ratio of the number of branches in successive orders of vessels or the branching ratio, is 3.58. The corresponding average diameter ratio is 1.72, whereas the average length ratio is 1.81.
本文呈现了猫右肺肺动脉的形态测量数据。制作了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动脉血管树的分支模式。这些数据是研究肺循环的任何定量方法所必需的。对于位于主肺动脉和毛细血管床之间的猫的所有肺血管，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。连续各级血管的分支数量比或分支比为3.58。相应的平均直径比为1.72，而平均长度比为1.81。
