The Renin-Angiotensin-Aldosterone System (RAAS) is a hormone system that regulates blood pressure and fluid balance. It is comprised of three main hormones: renin, angiotensin II, and aldosterone. The RAAS is primarily regulated by the rate of renal blood flow. It promotes oxidative stress in the brain, activating the RAAS and increasing sympathetic output, which can lead to hypertension when angiotensin II and aldosterone from the periphery act on the brain.

- 2. RAAS Renin-Angiotensin-Aldosterone System The Renin-Angiotensin-Aldosterone System (RAAS) is a hormone system within the body that is essential for the regulation of blood pressure and fluid balance. The system is mainly comprised of the three hormones renin, angiotensin II and aldosterone. Primarily it is regulated by the rate of renal blood flow.
- 6. The RAAS promotes oxidative stress in the brain, further activating the RAAS and augmenting sympathetic outflow. Angiotensin II and aldosterone of peripheral origin act in the brain to activate this cascade, increasing sympathetic outflow and leading to hypertension.
