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.

WebEach of these carries out a specific function. The proximal nephron absorbs about two-thirds of filtered sodium, without dissociating salt and water absorption. The thick ascending limb absorbs 25% of filtered Na+, but no water. The distal nephron absorbs 10% of filtered Na+ in close relation with K+ and, to some extent, H+ secretion. WebMay 14, 2024 · Figure 15.5.2.1 Freshwater kidneys. After solute reabsorption is complete, the urine is little more than water. Most of the nitrogenous wastes (including large amounts of ammonia, NH 3) leave by diffusion out of the gills.
