WebSdum reabsorption subsequently happens at four main sites in the nephron - the proximal tubule, loop of Henle, dstal tubule and collecting duct. Normally, about 99.4% of the filtered sodlum load is resorbed to maintain the con- stancy of total body sodium. The primary sites of this reabsorption are the proximal tu- bule and the loop of Henle. WebAll steps. Final answer. Step 1/5. 1. True. Reabsorption of water in the nephron occurs by active transport. Explanation: Reabsorption of water in the nephron occurs by active transport in certain segments of the nephron, such as the thick ascending limb of the loop of Henle and the early distal tubule. In these segments, water reabsorption is ...
