What is In a person on a very low potassium diet, which part of the nephron would be expected to reabsorb the most potassium? and explain in detail?
About 65% of the ﬁltered K+ is reabsorbed in the proximal tubule, and another 20% to 30% is  reabsorbed in the loop of Henle. Although most of the daily variation in K+ excretion is caused by  changes in potassium secretion in the distal tubule and CD (collecting duct), only a small percentage of the ﬁltered K+ load can be reabsorbed in these nephron segments.
