Web1 Dec 2008 · The reabsorption of water along the nephron thus leads to a rise in the tubular urea concentration. During hypovolemia, when levels of vasopressin are high and water is maximally reabsorbed, the inner medullary interstitial fluid urea concentration concomitantly rises, owing to the increased concentration gradient for the passive transport of urea out … The kidney's ability to perform many of its functions depends on the three fundamental functions of filtration, reabsorption, and secretion, whose sum is called renal clearance or renal excretion.

WebThe active reabsorption of sodium (a positively charged ion) into the blood leaves the fluid remaining in the proximal tubule electronegative with respect to the peritubular fluids. This provides a driving force for the reabsorptive transport of negatively charged ions such as chloride, bicarbonate, and organic solutes.
