Final answer:

Renin is produced by the juxtaglomerular cells of the kidneys, initiating the RAAS system to regulate blood pressure. Granular cells in the afferent arteriole secrete renin in response to decreased blood pressure or sympathetic nervous activity.


Explanation:

Renin is produced by the juxtaglomerular cells of the kidneys. These granular cells in the afferent arteriole secrete renin when they sense decreased blood pressure or sympathetic nervous activity, leading to the activation of the renin-angiotensin-aldosterone system (RAAS). Renin plays a crucial role in converting angiotensinogen into angiotensin I.
