Aldosterone (aka mineralocorticoid): Adrenal glands release aldosterone, causes kidney (distal tubules) reabsorb more Na+, which in turn causes more water reabsorption. ADH (made in hypothalamus, stored in pituitary): causes more water reabsorption in the kidney tubules, raising blood pressure.
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.
