Abstract

20例のイヌの肺を使用した。肺動脈は主として気管枝の外側または背側に沿って走る。右肺動脈は右前葉気管枝の腹側を通り,右中葉気管枝の背側を越えて背側気管枝系と外側気管枝系の間を右気管支の背外側に沿って後方に走る。その経過中,4気管枝系の各気管枝に沿って走る肺動脈枝を分枝する。左肺動脈は左中葉気管枝の背側を越えて右肺の場合と同様に分布する。肺静脈は主として気管枝の内側または腹側で気管枝と気管枝の間を走り,右肺では右前葉静脈と右中葉静脈は共同幹を形成して左心房に注ぎ,この他に右後葉肺静脈幹が流入する。右副葉静脈は右後葉肺静脈幹に注ぐ。左肺では左中葉静脈は2枝あり,短い共同幹を形成して左心房に注ぐ場合と,別々に注ぐ場合がある。この他に左後葉肺静脈幹が左心房に注ぐ。

Twenty dog lungs were examined. The right pulmonary artery runs across the ventral side of the right cranial lobe bronchiole, then across the dorsal side of the right middle lobe bronchiole. Thereafter, the right pulmonary artery runs along the dorso-lateral side of the right bronchus. During its course, the right pulmonary artery gives off arterial branches that run mainly along the dorsal or lateral side of each bronchiole. The left pulmonary artery runs across the dorsal side of the left middle lobe bronchiole, and thereafter has the same distribution as that in the right lung. The pulmonary vein runs mainly along the medial or ventral side of the bronchiole, and between the bronchioles. In the right lung, the right cranial and middle lobe veins form a short common trunk, when enter the left atrium. The right accessory lobe vein enters the right caudal lobe pulmonary venous trunk. The right caudal lobe pulmonary venous trunk enters the left atrium. In the left lung, the left middle lobe vein has two branches. Both enter the left atrium, forming a short common trunk. In addition to these veins, the left caudal lobe pulmonary venous trunk enters the left atrium.
