Hydrostatic pressures in the renal vasculature of hagfish have been studied. Estimates of the blood colloid osmotic pressure (COP) have been made. In blood vessels supplying the renal corpuscles, the average hydrostatic pressure is about 1 kPa. The average hydrostatic pressure falls to a value of 0.04 kPa within the postcardinal vein efferent to the renal corpuscle. Within the glomerular capillaries the hydrostatic pressure averages 0.21 kPa. Since the blood COP averages about 1.4 kPa, it is clear that glomerular filtration in the hagfish is not underlain by the hydrostatic pressure of the arterial pulse. In some blood vessels efferent to the renal corpuscles, hydrostatic pressure may be as high as in the afferent supply. Evidence is presented that the glomerular capillaries are shunted by this high pressure vascular pathway.
对盲鳗肾血管系统中的流体静压进行了研究。已对血液胶体渗透压（COP）进行了估算。在供应肾小体的血管中，平均流体静压约为1千帕。在肾小体传出的后主静脉内，平均流体静压降至0.04千帕。在肾小球毛细血管内，流体静压平均为0.21千帕。由于血液COP平均约为1.4千帕，显然盲鳗的肾小球滤过并非由动脉脉搏的流体静压所支撑。在一些肾小体传出的血管中，流体静压可能与传入供应血管中的一样高。有证据表明，肾小球毛细血管被这条高压血管通路分流。
