A person is experiencing a sudden decrease in systemic blood pressure. Which of the following will occur within the kidney to help control this blood pressure drop?

Question

Quizplus · Accepted Answer

When systemic blood pressure drops, juxtaglomerular cells within the kidney release the enzyme renin. Renin activates the renin-angiotensin-aldosterone system (RAAS), which helps to increase blood pressure by constricting blood vessels and retaining sodium and water within the body. The other options are not correct. A decrease in blood pressure would actually decrease the GFR, renal arteries would constrict to redirect blood to other organs, and an increase in osmotic pressure would have no effect on systemic blood pressure.
