本文研究了各年龄、非心肺疾病死亡患者死后肺动脉和大肺静脉环条的延伸性。容器带在张力平衡中承受不断增加的载荷。肺动脉容易扩张。这种可扩展性随着年龄的增长而减弱。肺静脉在各个年龄段几乎都无法扩张。大的肺实质外肺静脉可能在从肺向左心房供血方面起着容血作用。这可能是由于它们的可折叠性，因为它们几乎没有膨胀的能力。
The extensibility of circumferential strips of main pulmonary artery and large pulmonary veins obtained at post mortem from patients of all ages, dying from conditions other than heart and lung disease were studied. The vessel strips were submitted to increasing loads in a tension balance. The pulmonary arteries were readily extensible. This extensibility lessened with increasing age. The pulmonary veins were virtually inextensible at all ages. The large extraparenchymal pulmonary veins may have a capacitative role in supplying blood from the lungs to the left atrium. This may be accomplished by their collapsible nature, as they have little capability of distension.
