RAASjärjestelmän
RAASjärjestelmän, which translates to the "RAAS system," refers to the Renin-Angiotensin-Aldosterone System. This is a critical hormonal cascade that plays a significant role in regulating blood pressure and fluid balance within 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 directly increases blood pressure.
Dysregulation of the RAAS system is implicated in various cardiovascular diseases, including hypertension (high blood pressure),
