QuestionSBA
QuestionChoice
This is incorrect. Tubuloglomerular feedback is the mechanism by which the nephron alters the GFR according to changing Na+ concentration. A high Na+ concentration is detected by the macula densa in the distal convoluted tubule which stimulates the release of adenosine. This results in afferent arterial constriction to drop the GFR.
