Renin-Angiotensin-Aldosterone System (RAAS) & Renal Artery Stenosis

This module begins by exploring how the renin-angiotensin-aldosterone system (RAAS) maintains homeostasis by preventing a decrease in glomerular filtration rate (GFR) during periods of low blood pressure. It then examines the role of angiotensin II as the key effector in preserving GFR throughout the body. Finally, the module addresses renal artery stenosis, a condition in which chronic RAAS activation leads to pathologically elevated blood pressures
