RAASjärjestelmässä
RAASjärjestelmässä, often referred to as the Renin-Angiotensin-Aldosterone System (RAAS), is a vital hormonal cascade that plays a crucial role in regulating blood pressure and fluid balance within the body. This complex system is activated when the body detects a drop in blood pressure or reduced blood flow to the kidneys.
The primary trigger for RAAS activation is the release of renin from the kidneys. Renin then acts
Angiotensin II is a potent vasoconstrictor, meaning it narrows blood vessels, which directly increases blood pressure.
The RAAS is a tightly regulated system. While essential for maintaining adequate blood pressure, its overactivation
