WebIntroduction. The distal convoluted tubule (DCT) is the portion of the nephron that is immediately downstream of the macula densa. Although the DCT is the shortest segment of the nephron, spanning only about 5 mm in length in humans (), it plays a critical role in a variety of homeostatic processes, including sodium chloride reabsorption, potassium … WebWorking on nephron update for empagliflozin and obesity - nephron-empa-obese/computation_parallel.py at main · mstadt/nephron-empa-obese WebMar 23, 2024 · The proximal convoluted tubule (PCT) is the site where maximum reabsorption of water and salts takes place. The collecting duct and distal convoluted tubule (DCT) are the final reabsorption sites in the nephron.
