在双侧颈动脉闭塞和中度和重度出血期间，通过体积描记技术测量迷走神经切断犬的脾、肝和肠的血容量的反射性减少。在颈动脉闭塞和中度出血期间，从每个器官动员的血液量为各自血容量的6%至30%，在重度出血期间为55%至81%。在每一种实验情况下，脾脏表现出最大的释放血液的能力，而肠则表现出最小的释放血液的能力。在中度出血（9 ml/kg）期间，脾脏产生的体积等于失血量的35%，肝脏为14%，肠为7%。严重出血的可比数字分别为26%、13%和5%。内脏循环的组成区域在作为血液储存器的功能方面的这种排序顺序可能是狗特有的
The reflex decrease in blood volume of the spleen, the liver, and the intestine of vagotomized dogs was measured by plethysmographic techniques during bilateral carotid occlusion and moderate and severe hemorrhage. The volume of blood mobilized from each organ during carotid occlusion and moderate hemorrhage was from 6 to 30% of their respective blood volumes and from 55 to 81% during severe hemorrhage. In each experimental situation the spleen exhibited the greatest ability to release blood and the intestine, the least. During moderate hemorrhage (9 ml/kg) the spleen yielded a volume equal to 35% of the blood lost, the liver 14% and the intestine 7%. Comparable figures for severe hemorrhage were 26, 13, and 5%, respectively. This order of ranking the component regions of the splanchnic circulation with regard to function as a blood reservoir may be specific for the dog
