Renin is released from the kidney in all except________________?
Correct answer: D. Decrease in the concentration of sodium ions in the proximal tubules
- A. Sympathetic stimulation
- B. Fall in the BP
- C. Decrease in the concentration of sodium ions in the distal tubules
- D. Decrease in the concentration of sodium ions in the proximal tubules
Explanation
Renin release is stimulated by sympathetic activity, reduced renal perfusion pressure and reduced NaCl delivery to the macula densa in the distal tubule. A fall in sodium concentration in the proximal tubule is not the recognized direct trigger.
