To provide an accurate measure of renal blood flow,a test substance should be:
A) Filtered by the glomerulus
B) Reabsorbed by the tubules
C) Secreted by the distal convoluted tubule
D) Cleared on each contact with functional renal tissues

Question

Quizplus · Accepted Answer

A test substance that is cleared on each contact with functional renal tissues provides the most accurate measure of renal blood flow as it is effectively removed from the bloodstream by the kidneys during filtration, reabsorption, and secretion. Test substances that are filtered by the glomerulus or reabsorbed by the tubules may not accurately reflect the true renal blood flow, while substances secreted by the distal convoluted tubule may not be present at high enough concentrations to provide an accurate measure.
