Within the LOOP OF HENLE, the descending limb allows for the reabsorbtion of water through osmosis whereas the ascending limb allows for the passive and active transport of salts such as sodium to move out of the tubules and be reabsorbed.ccuring more commonly within the nephron system than filtration, this is a form of active transport which takes the the useful substances for the body from the tubules and places them back into the blood filled capillaries.
Magnitude of Proximal Tubule Reabsorption. Since PNa = 145 mEq/L and GFR = 180 L/day, then 26100 mEq Na/day (equivalent to Na in 1.566 kilogram salt) are filtered. Only 300 mEq Na/day are excreted in the urine. Thus, about 99% is reabsorbed by the kidneys. Most of the Na reabsorption takes place in the proximal tubule. The (TF/P)inulin = 3 by the end of the proximal convoluted tubules(PCT). This indicates that only 1/3 of the filtered water remains by the end of the PCT and two thirds have been reabsorbed.
