Reabsorption in the __ is critical for the recapture of ions, water, and valuable nutrients from teh huge initaial filtrate volume. NaCl in the filtrte diffuses into the cells of teh transport epithelium, were Na+ is the actively transported into the interstitial fluid. This transfer of positivve charge out of the tubule drives the passive transport of Cl-. As salt moves from the filtrate to the interstitial fluid, water follows by osmosis. THe salt and water then diffuse from the interstitial fluid into the __. Glucose, amino acids, potassium ions, and other essential substances are also actively or passively transported from the filtrate to the interstitial fluid and then into teh __.
