astra-53 [7]

Answer: True

Explanation:

Renin ( angiotensinogenase), is an aspartic protease protein which is secreted by kidney that participates in the body's renin – angiotensin – aldosterone network that mediates arterial vasoconstriction and extracellular fluid volume.

Renin is released by cells of the juxtaglomerular apparatus in response to the stimuli of decrease in arterial blood pressure and the degree of stretch of the arteriole wall.

Hence, the statement is true.
