Which statement regarding Furosemide's effect on the macula densa is correct?
Show answer and explanation
Correct answer: It blocks macula densa chloride sensing, triggering renin release
Loop diuretics inhibit NKCC2 in the macula densa cells. This prevents them from sensing the luminal chloride concentration, which 'tricks' the kidney into thinking blood pressure is low, thereby triggering the release of renin.
