The most important system involved in the regulation of systemic blood pressure, renal blood flow, and glomerular filtration rate is called the renin-angiotensin-aldosterone system, or (RAAS) for The renin-angiotensin system or RAS regulates blood pressure and fluid balance in the body. When blood volume or sodium levels in the body are low, or blood potassium is high, cells in the kidney release the enzyme, renin. Renin converts angiotensinogen, which is produced in the liver, to the hormone angiotensin I. The release of Renin is what causes the cascade known as the Renin-Angiotensin-Aldosterone system. So let’s look at the Renin Angiotensin Aldosterone System – or the RAAS one step at a time. First, we get a stimulus – again it could be hyponatremia, low blood pressure, or low perfusion to the kidneys.

Although synthesis of aldosterone is the final step in the RAAS cascade, the intermediate component Angiotensin II also has potent physiological effects as discussed in the next section. Angiotensin II is the major bioactive product of the renin–angiotensin system, binding to receptors on intraglomerular mesangial cells, causing these cells to contract along with the blood vessels surrounding them and causing the release of aldosterone from the zona glomerulosa in the adrenal cortex. Background: The renin-angiotensin aldosterone system (RAAS) is a hormonal cascade that functions in the homeostatic control of arterial pressure, tissue perfusion, and extracellular volume. Dysregulation of the RAAS plays an important role in the pathogenesis of cardiovascular and renal disorders. This system is very important in managing our blood pressure, especially when the blood pressure falls too low. In addition, nurses should know how the renin-angiotensin-aldosterone system works so they can understand how certain cardiac medications (like ACE inhibitors) work to lower the blood pressure in the body.

Ökar utsöndringen av Na, Cl i distala tubuli. Sänker fyllnadstryck (preload) och minskar vätskeöverskott vilket ger RAAS-aktivering varför de bör kombineras med ACEI. Risk för hyponatremi (gäller även spironolakton) och hypokalemi.

Increasing salt and water retention by the kidneys, The RAAS also significantly impacts tubular reabsorption in the nephron and collecting system in order to influence electrolyte balance and blood volume, in Nov 1, 2018 Angiotensin consists of a group of hormones that are part of the renin- angiotensin system. To create angiotensin, the liver first creates a protein Renin is an enzyme, also produced by the kidneys, that plays an important role in the renin–angiotensin–aldosterone hormonal system, which helps to control The renin-angiotensin system or RAS regulates blood pressure and fluid balance in the body.

The RAAS plays a central role in the pathogenesis of hypertension and CKD. 15–18 Inappropriate activation of intrarenal RAAS, resulting in enhanced angiotensin II (Ang-II) generation has also been suggested to contribute to progression of CKD, 16 but the mechanisms involved in RAAS-induced Activity of the renin-angiotensin-aldosterone system (RAAS) is increased in patients with heart failure, and its maladaptive mechanisms may lead to adverse effects such as cardiac remodelling and sympathetic activation. The renin–angiotensin system (RAS), or renin–angiotensin–aldosterone system (RAAS), is a hormone system that regulates blood pressure and fluid and electrolyte balance, as well as systemic vascular resistance.
