Show transcribed image text Glomerular filtration brings glucose into the nephron. Normally, all the glucose filtered into the nephron is returned to the peritubular capillaries by reabsorption at the proximal tubule, so that no glucose is present in the urine. Diabetics have increased levels of blood glucose, which leads to an increase in the amount of glucose present in the filtrate. Not all of this glucose gets reabsorbed, resulting in measurable glucose levels in the urine. A common symptom of diabetes is an increase in the volume of urine produced. Based on what you know about how the kidney works, how can you explain this symptom?
