Renin Angiotensin Aldosterone System - RAAS

Explore the intricacies of the Renin Angiotensin Aldosterone System (RAAS) in this comprehensive 59-minute lecture. Delve into the mechanisms of renin production, including intrarenal and extrarenal pathways, and understand the role of the juxtaglomerular apparatus. Learn about the conversion of angiotensinogen to angiotensin-2 and its various effects on blood pressure regulation. Examine the actions of aldosterone on principal cells in the distal convoluted tubules and collecting tubules. Discover the impact of RAAS on the central nervous system, including ADH production and thirst center activation. Finally, investigate the pathological functions of RAAS in conditions like congestive cardiac failure and the importance of RAAS-blocking drugs in preventing cardiac remodeling.
