Which sequence correctly describes the RAAS activation leading to increased blood pressure?

• A. Macula densa senses low GFR -> Renin release -> Angiotensin II increases SVR -> Aldosterone increases preload
• B. Aldosterone release -> Angiotensin II increases SVR -> Macula densa senses low GFR
• C. Renin release -> Aldosterone increases preload -> Angiotensin II increases SVR -> Macula densa senses low GFR
• D. Angiotensin II increases SVR -> Macula densa senses low GFR -> Renin release

Answer: (A)
