<prompt> The highest percentage of glomerular filtrate reabsorption occurs in:Bowmans capsuleProximal tubuleThick ascending limb of loop of HenleDistal tubule  <response>: Under all circumstances most of the filtrate is reabsorbed in the proximal tubule. Normally, this reabsorption amounts to about two-thirds of the sodium and water filtered. Normally 60 of Na is reabsorbed in the proximal tubule, primarily by Na-H exchange.
