Proximal tubule water reabsorption

WebbThe proximal tubule is responsible for the reabsorption of the largest fraction of filtrate. It reabsorbs about 70% of filtered NaCl and water and 100% of the filtered glucose and amino acids. Reabsorption is a highly specific process that occurs through specific proteins located on the apical membrane of kidney tubule cells. Webb7 juli 2024 · Advertisement Reabsorption and Secretion in the Distal Convoluted Tubule Approximately 80 percent of filtered water has been recovered by the time the dilute filtrate enters the distal convoluted tubule. The distal convoluted tubule will recover another 10–15 percent before the filtrate enters the collecting ducts. What is the primary …
