对4只白手长臂猿(Hylobates Agilis)的肺进行了检查。右肺动脉穿过右上叶细支气管的腹侧，然后横穿右中叶细支气管的背侧。此后，它沿右支气管背外侧，在背细支气管系和侧细支气管系之间，逐渐跟随右支气管背侧方。在其过程中，它发出沿每个细支管的动脉分支。与右肺一样，左肺动脉穿过左中叶细支气管的背侧，然后沿着左支气管。肺动脉的分支主要沿细支管的背侧或外侧走行，而肺静脉主要在细支管的内侧或细支管之间走行。然而，在少数部分，肺静脉走行于细支气管的外侧。最后，经右上叶静脉、右中叶静脉共同干、右下叶肺静脉干、左中叶静脉、左下叶肺静脉干4条大静脉进入左房。
The lungs of four white handed gibbons (Hylobates agilis) were examined. The right pulmonary artery runs across the ventral side of the right upper lobe bronchiole, and then traverses the dorsal side of the right middle lobe bronchiole. Thereafter, it runs along the dorso-lateral side of the right bronchus, between the dorsal bronchiole system and the lateral bronchiole system, and gradually follows the dorsal side of the right bronchus. During its course, it gives off arterial branches which run along each bronchiole. The left pulmonary artery runs across the dorsal side of the left middle lobe bronchiole and then along the left bronchus as in the right lung. The branches of the pulmonary artery run mainly along the dorsal or lateral side of the bronchiole, while the pulmonary veins run mainly the medial side of the bronchioles or between them. However, in a few portions, the pulmonary veins run the lateral side of the bronchioles. Finally, they enter the left atrium with four large veins i.e. the common trunk of the right upper lobe vein and right middle lobe vein, right lower lobe pulmonary venous trunk, left middle lobe vein, and left lower lobe pulmonary venous trunk.
