B i.e. PotassiumPotassium once filtered in the tubular fluid is reabsorbed only in the proximal tubules. Nowhere else it is reabsorbed so it is not reabsorbed in the DCT, rather it is secreted into the tubular fluid in DCTQ.Water reabsorption in DCTEarly pa of distal tubule is impermeable to water.Late DCT becomes permeable under the influence of ADH.
