प्रश्न
In which segment of the nephron most of the re-absorption of substances takes place?
Advertisements
उत्तर
In proximal convoluted tubule cells, Glucose, lactate, amino acids, Na+ and water, are reabsorbed. In the descending limb of Henle’s loop, water is reabsorbed. In the ascending limb, Na+, Cl and K+ are reabsorbed. In the distal convoluted tubule, water is reabsorbed.
