Detailed explanation-1: -Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream.
Detailed explanation-2: -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 salty, so more water leaves through passive diffusion.
Detailed explanation-3: -The collecting duct of a nephron is normally impermeable to water. In the presence of antidiuretic hormone (ADH), aquaporin proteins are inserted, making the collecting duct permeable to water.
Detailed explanation-4: -Water moves out of tubular filtrate at the descending limb due to osmotic pressure differences between the tubular filtrate and interstitial fluid. This causes the tubular filtrate to become more and more concentrated as it descends.
