通过直接观察证实，从兔子最小的肠系膜根到体重14公斤的狗的腹腔静脉都存在层流。犬腔静脉内雷诺数最高可达1000。在人类中，在轻度运动中可以达到2000个。在胸椎腔静脉中，血流有明显的阶段性变化，血流模式更为复杂。讨论了呼吸运动对血管腔和血流模式的影响。
The presence of laminar flow by direct observation was confirmed in veins ranging from the smallest mesenteric radicles of the rabbit to the abdominal vena cava of a dog weighing 14 kg. Reynolds numbers in the dog vena cava were 1000 at maximum. In the human the number of 2000 may be reached in mild exercise. In the thoracic venae cavae, where marked phasic variations in flow were present, the flow pattern was more complex. The effect of respiratory movements on the vessel lumen and flow pattern is discussed.
