WebThe function of the outer medullary collecting duct is to raise further the absolute intraluminal urea concentration. Finally, the inner medullary collecting duct has two major functions in urinary concentration: first, it adds net urea to the papillary interstitium, and second, it allows the generation of maximally concentrated urine due to ... WebStep 6: Collecting Ducts. At the end of the distal convoluted tubule, the filtrate empties into collecting ducts, where it combines with filtrate from other nephrons. Collecting ducts move back into the medulla, which is … WebJul 30, 2024 · That recovery occurs in the PCT, loop of Henle, DCT, and the collecting ducts. Various portions of the nephron differ in their capacity to reabsorb water and specific solutes. While much of the reabsorption and secretion occur passively based on concentration gradients, the amount of water that is reabsorbed or lost is tightly regulated. johnson honda of stuart used cars
