The clearance rate for a substance that is filtered and secreted but not reabsorbed is greater than the GFR.

Question

Quizplus · Accepted Answer

If a substance is filtered and secreted but not reabsorbed, it means that it is being actively transported from the blood into the filtrate in the kidney tubules. This increases the amount of the substance that is eliminated from the body compared to the amount filtered by the glomerulus alone, resulting in a clearance rate that is greater than the GFR.
