WebThe tubule compartments of the nephron include: the proximal tubule (convoluted and straight), the descending tubule, the ascending tubule, the loop of Henle, the distal tubule (early and late) and the collecting duct. The purpose of the tubule components is to selectively reabsorb tubule fluid back into the blood. If the majority of the fluid ... WebThe proximal tubule is the only site for glucose reabsorption. If the filtered load of glucose overwhelms the proximal tubule transport mechanisms, glucose escapes to the loop of Henle. There is no reabsorption of glucose beyond the proximal tubule, and the glucose becomes progressively more concentrated as the nephron reabsorbs water and salt. iou符号
