Sodium Regulation: Renin-Angiotensin-Aldosterone System (RAAS)

This lesson explores how the renin-angiotensin-aldosterone system (RAAS) regulates blood pressure (i.e., effective circulating volume). In particular, how effective circulating volume (ECF) is monitored by baroreceptors, how sympathetic activation of granular cells leads to synthesis and release of renin, how renin leads to the formation of angiotensin II, the role of angiotensin II and sodium regulation and blood pressure, how aldosterone stimulates sodium reabsorption along the collecting duct. For help preparing for an exam on this and […]
