Certain aspects of renal tubular transport of water, sodium, chloride, and bicarbonate are considered with emphasis on data obtained by micropuncture concerning localization and mechanism of transport. All water movement is believed to be passive and secondary to solute transport. Sodium transport is considered to be active, since sodium can be reabsorbed against an electrical and chemical concentration gradient even in the proximal tubule. The transtubular potential difference (luminal fluid negative to interstitial fluid) is believed to result primarily from the active transport of sodium out of the tubule. The fall in pH of proximal fluid is of such magnitude
