WebThe reabsorption of water in the earlier parts of the nephron (regardless of a person's state of hydration), independent of ADH is termed as 'obligatory reabsorption of water', whereas the water reabsorption in the distal part of the nephron (in accordance with the body's state of hydration), under the influence of ADH, is termed as 'facultative reabsorption of water'. WebKidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: Specialized proteins called transporters are located on the membranes of the various cells of the nephron. These transporters grab the small molecules from the filtrate as it flows by them.
