WebIn the distal convoluted tubules and collecting ducts of the kidneys, aldosterone stimulates the synthesis and activation of the sodium-potassium pump. Sodium passes from the filtrate, into and through the cells of the tubules and ducts, into the ECF and then into capillaries. Water follows the sodium due to osmosis. WebIntroduction. The distal convoluted tubule (DCT) is the portion of the nephron that is immediately downstream of the macula densa. Although the DCT is the shortest segment of the nephron, spanning only about 5 mm in length in humans (), it plays a critical role in a variety of homeostatic processes, including sodium chloride reabsorption, potassium …
