Flow autoregulation in the arteriolar network serves to maintain the capillary-tissue fluid balance by regulation of capillary pressure. In the present study, we have examined theoretically the effects of arteriolar vasomotion and venous pressure elevation on the capillary fluid exchange, the interstitial fluid pressure, and the interstitial osmotic pressure during capillary pressure regulation. We used Starling's hypothesis and extended it to include a consideration of a parallel hetero-porous pathway and to determine the effects of plasma protein filtration on interstitial fluid pressure and osmotic pressure. We have found that arteriolar vasomotion plays a primary role in protecting the capillary-tissue fluid balance during the elevation of capillary flow and that it is a secondary mechanism for the regulation of capillary arterial pressure.
小动脉网络中的血流自动调节通过调节毛细血管压力来维持毛细血管-组织液平衡。在本研究中，我们从理论上研究了小动脉血管运动和静脉压力升高对毛细血管压力调节过程中毛细血管液体交换、组织间隙液压力和组织间隙渗透压的影响。我们采用了斯塔林假说，并对其进行扩展，纳入了对平行异孔道的考虑，以确定血浆蛋白滤过对组织间隙液压力和渗透压的影响。我们发现，在毛细血管血流增加时，小动脉血管运动在保护毛细血管-组织液平衡方面起主要作用，并且它是调节毛细血管动脉压的次要机制。
