By intraarterial injection of silicone rubber we visualized the main feeding vessels of the rabbit trachea. They originate from the right subclavian artery and supply bilateral longitudinal tracheo-esophageal arteries. These lie in the groove between the trachea and the esophagus, giving off numerous segmental branches to both of these organs. In the trachea these pass submucosally between the tracheal cartilages, feeding a rich capillary network within the mucosa. The membranous part of the trachea is extremely well supplied with vessels, originating in arteries running longitudinally in the space between the trachea and the esophagus. The mucosa contains many sinusoidal ectasias, forming an almost cavernous arrangement in the tracheal wall. It is probable that these vessels are of great importance for the conditioning of inhaled air. Experimental studies on intubated animals have shown that a large-volume tracheal tube cuff, inflated to a pressure of 50 mm Hg, decreases or completely hinders capillary silicone rubber perfusion of the tracheal mucosa.
通过动脉内注射硅橡胶，我们观察到了兔气管的主要供血血管。它们起源于右锁骨下动脉，供应双侧纵向气管食管动脉。这些动脉位于气管和食管之间的沟内，向这两个器官发出许多节段性分支。在气管中，这些分支在气管软骨之间的黏膜下层穿行，为黏膜内丰富的毛细血管网供血。气管的膜部血管供应极为丰富，起源于在气管和食管之间的间隙纵向走行的动脉。黏膜含有许多窦状扩张，在气管壁内形成几乎海绵状的结构。这些血管可能对吸入空气的调节非常重要。对插管动物的实验研究表明，充气压至50毫米汞柱的大容量气管导管套囊会减少或完全阻碍气管黏膜的毛细血管硅橡胶灌注。
