.../user-licence-1-1/ Summary: Magnetic resonance imaging showed accumulation of the injected tracers in the kidney. The atrial wall of the Mytilus galloprovincialis could filtrate small molecules (<0.5 kDa), but not larger molecules. Nephridia Glomerular filtration T 1 relaxation...

... collected naturally voided urine. As a percentage of the infusion rate, glomerular filtration rate increased by about 135%, but urine flow rate (UFR) by only 80 %, reflecting increased tubular reabsorption of H 2 O. During NaCl infusion, virtually all of the extra Na + and Cl - filtered was reabsorbed...

... was varied indicate that P GC reflects the area of the active capillaries and the rate of perfusion. Therefore, in the hagfish, P GC appears to be an effect of factors that cause glomerular filtration, not the main cause of that process. Although there is considerable scatter, the data of Table 1 reveal...

... 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...
