Potassium is maximally absorbed in which pa of nephron?
Much of the filtered K+ is removed from the tubular fluid by active reabsorption in the proximal tubules K+ is then secreted into the fluid by the distal tubular cells. In the absence of complicating factors, the amount secreted is approximately equal to the K+ intake, and K+ balance is maintained. Ref: Ganong 25th ed/page 681
