A similarity of the blood flow shifts in response to every single pressor or depressor stimulus in the v. cava anterior in cats and a possibility of dissimilar changes of capacity of the vein's vascular basin under the effect of one and the same stimulus, are revealed. This dissimilarity is mainly due to a skin-muscular component of this vascular basin. An increase in the central venous pressure from 0 to 40 mm of water limits the extent of shifts in the capacity function of the v. cava anterior's basin. The blood flow changes in the v. cava anterior is mainly due to a relationship among regional components of the vessels' total peripheral resistance. A potential possible contribution of the v. cava anterior basin vessels capacitance's shifts constitutes 17.5%, whereas under the effect of neurogenic stimuli in the increase of the blood flow in the v. cava anterior may be completely (up to 100%) maintained by a drop of the capacitance of the vein's vascular basin.
揭示了猫前腔静脉中对每一种单一升压或降压刺激的血流变化的相似性，以及在同一刺激作用下静脉血管床容量可能发生不同变化的可能性。这种差异主要归因于该血管床的皮肤-肌肉成分。中心静脉压从0升高到40毫米水柱限制了前腔静脉血管床容量功能的变化程度。前腔静脉中的血流变化主要归因于血管总外周阻力的区域成分之间的关系。前腔静脉血管床容量变化的潜在可能贡献为17.5%，而在前腔静脉血流增加的神经源性刺激作用下，静脉血管床容量的下降可能完全（高达100%）维持这种增加。
