Quizplus · Accepted Answer

When plasma glucose exceeds the renal threshold, it means that the transport maximum (Tm) for glucose reabsorption in the kidneys has been surpassed. As a result, glucose remains in the urine, drawing water with it through osmosis, which leads to an increase in urine flow, a process known as osmotic diuresis.
