All of the Following Would Result in an Increase in Renin

Question

All of the following would result in an increase in renin release except
A) decreased blood pressure at the glomerulus.
B) blockage in the renal artery.
C) increased blood volume.
D) stimulation of juxtaglomerular cells.
E) decreased osmotic concentration at the macula densa.

Accepted Answer

Renin is released in response to a decrease in blood pressure at the glomerulus, a blockage in the renal artery, stimulation of juxtaglomerular cells, and decreased osmotic concentration at the macula densa. However, an increase in blood volume causes stretch receptors in the atria to be activated, resulting in the inhibition of renin release. Therefore, option C would not result in an increase in renin release.
