The Renin-Angiotensin-Aldosterone [RAAS] Pathway EXPLAINED

The video explains the RAAS system, a crucial pathway in health disciplines for regulating blood pressure. It describes how low blood volume or pressure triggers the release of renin from the kidneys, converting angiotensinogen from the liver into angiotensin I, which is then converted to angiotensin II in the lungs. Angiotensin II stimulates aldosterone release, increasing sodium and water reabsorption in the kidneys, thus raising blood pressure. It also causes vasoconstriction, further increasing pressure. The video concludes with a brief mention of medications affecting this system.
