Exercise 19

Secretion of renin is stimulated by:

A. Juxtaglomerular cells

B. Angiotensin I and II

C. Macula densa cells

D. Circulating angiotensin-converting enzyme

Step 1 of 2

Renin:

Renin is an enzyme produced by juxtaglomerular of nephron (kidney). It participates in the renin-angiotensin aldosterone system thereby regulating the blood pressure.

Renin is formed during the following stimulus:

• blood pressure.ceasation

• Decrease in sodium level in nephron.

• sympathetic nervous system action.

• The macula densa cells stimulate renin secretion by signaling the juxtaglomerular cells when there is a cease in tubular fluid volume.

• The macula densa cells and juxtaglomerular together called as juxtaglomerular complex.

Therefore, “macula densa cells” stimulates to produce renin. Hence, the correct answer is option.
