Question

Renin is released from

• A. juxtaglomerular apparatus
• B. cortical nephron
• C. collecting duct
• D. pelvis

Answer 1

The correct option is A juxtaglomerular apparatus

Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls. The juxtaglomerular cells are also stimulated to release renin by signalling from the macula densa.
