Granular cells of the juxtaglomerular apparatus respond to decreased blood volume and increased sympathetic nerve activity by secreting

Question

Quizplus · Accepted Answer

Granular cells in the juxtaglomerular apparatus are responsible for secreting renin in response to a decrease in blood volume or blood pressure, or an increase in sympathetic nerve activity. Renin is an enzyme that plays a role in the renin-angiotensin-aldosterone system, which helps regulate blood pressure and fluid balance.

B, C, and D are incorrect as inulin is not secreted by granular cells, angiotensinogen is produced by the liver, and natriuretic hormone is secreted by the heart in response to changes in blood volume and pressure.
