When the concentration of glucose in the blood flowing through the kidneys is within the normal range, most of the glucose within the nephron tubule is reabsorbed by the blood. Glucose is filtered from the blood into the Bowman’s capsule at the glomerulus, but it is then reabsorbed by the proximal convoluted tubule and returned to the bloodstream. Glucose is not normally pumped into the collecting duct and is not normally secreted back into the blood by the Bowman’s capsule. Additionally, when blood glucose levels are normal, most glucose that passes into the nephron tubule is reabsorbed and does not end up in the urine.
