RAASaktiivisuus
RAASaktiivisuus refers to the activity of the Renin-Angiotensin-Aldosterone System (RAAS). This is a complex hormonal cascade that plays a crucial role in regulating blood pressure, fluid balance, and electrolyte levels in the body. The system is initiated when the kidneys detect a drop in blood pressure or blood volume, or a decrease in sodium levels.
In response, the kidneys release an enzyme called renin. Renin then acts on angiotensinogen, a protein produced
Angiotensin II is a potent vasoconstrictor, meaning it narrows blood vessels, which increases blood pressure. It
Dysregulation of RAASaktiivisuus is implicated in various cardiovascular and renal diseases. Conditions like hypertension (high blood
