Which correctly describes renin?

Question

Quizplus · Accepted Answer

Renin is primarily secreted by juxtaglomerular cells in the renal afferent arterioles in response to several stimuli, including low blood pressure, low blood volume, and low sodium levels.

Answer: B 
 The secretion of renin is enhanced by low levels of Na⁺ in the macula densa, which is a specialized region of the distal convoluted tubule.

Answer: C 
 Renin secretion is stimulated by decreased blood pressure or decreased blood flow to the kidneys, which occurs in the renal afferent arterioles.

Answer: D 
 Renin acts on angiotensinogen to produce angiotensin I, which is then converted to angiotensin II. Angiotensin II acts on the adrenal cortex to stimulate aldosterone secretion.

Answer: E 
 Renin is not secreted by the liver, and its secretion is not directly stimulated by low blood pressure.
