RAAS System Made Easy for Nursing Students and Nurses
The RAAS system stands for Renin-Angiotensin-Aldosterone System. When fluid volume deficit occurs (too little fluid in the body) a low blood pressure will develop.
The body doesn’t like low blood pressure and has built-in monitoring systems to surveillance the body and increase the blood pressure as needed. One of those systems is called the RAAS.

Renin Angiotensin Aldosterone System (RAAS) Nursing Mechanism for Blood Pressure
Renin-angiotensin-aldosterone system (RAAS) nursing review for how this system manages the blood pressure via the kidneys.
The RAAS helps manage the blood pressure, especially when the blood pressure is too low.
⭐Fluid and Electrolytes eBook: https://registerednursern.creator-spring.com/
When the body senses the blood pressure is too low the sympathetic nervous system will sends nerve impulses to the juxtaglomerular cells in the kidneys. These cells will release renin.
When renin enters the circulation, it will cause a substance in the liver to become activated called angiotensinogen. Angiotensinogen will turn into angiotensin I. As angiotensin I presents in the system it will signal to ACE (angiotensin-converting-enzyme) to convert the angiotensin I into angiotensin II.

Flüssigkeitsvolumen, Osmolarität und Blutdruck hängen direkt miteinander zusammen und werden gemeinsam in engen Grenzen reguliert. Dabei ist das Zusammenspiel der Enzymen und Hormonen wichtig, die die Menge an resorbiertem Natrium und Wasser in der Niere auf die Verhältnisse im Körper abstimmt. Die Rede ist vom sogenannten RAAS.
In dieser Folge des Auditors erfährst du wie genau die Enzyme und Hormone zusammenarbeiten und welche Wirkungen sie haben.

Renin-angiotensin-aldosterone system
♬ Ain't nothin' gonna break my stride, nobody gonna slow me down, oh no,
I got to keep blood moving! ♬ Today's #ClinicalCuts is all about the renin-angiotensin-aldosterone system, which helps keep blood movin'.
The main job of the cardiovascular system is to keep the blood moving, and to help facilitate that, blood pressure and other critical functions are kept under tight control. A major way the body does that is through a set of hormones that make up the renin-angiotensin-aldosterone system.
Renin is an enzyme that gets into the plasma and looks for its primary substrate, angiotensinogen.
Angiotensinogen is a large protein made up of over 400 amino acids that’s produced by the liver and is always hanging out in the blood.
When they meet up, renin cleaves off a huge chunk of the angi...

The renin–angiotensin–aldosterone system, RAAS, is a hormonal system that controls blood pressure. While baroreflex is a short-term response to sudden changes in blood pressure, RAAS is responsible for long-term regulation.
In the kidneys, within the walls of afferent arterioles, there are specialized cells producing prorenin called juxtaglomerular cells. Upon activation by a drop in blood pressure, prorenin is cleaved to form renin, which is released into the blood. Renin converts a plasma protein called angiotensinogen, produced by the liver, into angiotensin I, a peptide of 10 amino acids. Angiotensin I is further converted into angiotensin II, an 8-amino acid peptide, by the angiotensin-converting enzyme, ACE, predominantly present in the lungs and kidneys.
Angiotensin II is a hormone. It binds to angiotensin II receptors in tissues to exert various effects:
- It promotes sodium reabsorption in proximal convoluted tubules of the kidneys.
- It stimulates vasoconstriction in systemic arterioles.
- It induces the release of aldosterone from the adrenal cortex. Aldosterone promotes sodium and water retention in the kidneys.
- In the central nervous system, angiotensin II has several effects:
+ It acts on the hypothalamus to stimulate thirst and encourage water intake.
+ It induces the posterior pituitary to release antidiuretic hormone, which promotes water retention by the kidneys.
+ It reduces the sensitivity of the baroreceptor response to increased blood pressure, so that this response would not counteract the effect of RAAS.
All these actions lead to an increase in blood volume and blood pressure.
Angiotensin II is short-lived with a half-life of 1 to 2 minutes. It is degraded into angiotensin III and IV, which have lesser effects.
Overactive or inappropriately activated RAAS is a cause for hypertension.
RAAS is a frequent target of anti-hypertensive drugs. ACE inhibitors and angiotensin receptor blockers are common treatment for hypertension.

Angiotensin II is a major vasoconstrictor that will cause vasoconstriction and trigger the adrenal gland and pituitary gland to release substances to help increase blood volume.
The adrenal gland will release aldosterone, which will cause the kidneys to keep sodium and water. The pituitary gland will release ADH (antidiuretic hormone), which will cause the kidneys to keep water. All of this together will increase systemic vascular resistance and blood pressure.

Explaining RAAS with the help of a case of hemorrhage; Low Renal Perfusion leading to Renin release from kidney.
Renin production in detail;
Low blood flow in Afferent arterioles; Polkissen are the modified afferent arteriolar smooth muscles that are able to measure blood flow to nephrons.
Low blood flow to nephrons; Polkissen releases Renin into the blood.
Second mechanism of Renin production: Na-sensing device in DCT; Macula Densa.
Polkissen measures blood flow/pressure and is derived from afferent arterioles; while Macula Densa is a Na-measuring device derived from nephrons in the kidney.
Polkissen and Macula Densa are held together by connective tissues; as a complex; known as Juxta Glomerular Apparatus (JGA).
Low Renal Perfusion leads to low Glomerular Filtration; slow movement of filtrate through nephrons; leads to increased Na+ reabsorption and ultimately decreased amount of Na+ reaching the Macula Densa of JG apparatus.
Polkissen of JG apparatus receive that message; and increases production of Renin.
Both are Intrarenal Mechanisms of Renin Production.
Extrarenal or Systemic Mechanism of Renin Production:
Baroreceptors in Carotid Sinus; Low blood flow activates them; message to CNS; Vasomotor Center (in Medulla) activated; stimulates the Sympathetic Outflow.
Sympathetic fibers in JG apparatus release Norepinephrine (NE) to act on Beta1-adrenergic receptors in JG apparatus; leading to increased production of Renin by JG apparatus.
Function of Renin: will go into systemic circulation through the renal vein.
Angiotensinogen (ATG); produced by the liver. Renin; (which is an enzyme) will act on ATG and convert ATG into Angiotensin-1(AT-1).
AT-1 gets converted into AT-2; enzyme in the lung (on the surface of endothelial cells) responsible for this conversion = Angiotensin Converting Enzyme (ACE).
ACE inhibitors (Captopril, Enalapril).
Bradykinin (a vasoconstrictor); is also broken down/inactivated by ACE; thus, doubly ensuring vasodilation.
Recap.
Actions of AT-2: AT-2 receptors are present in venous smooth muscles; AT-2 acts on them to cause venoconstriction; which increases Venous Return; increased Stroke Volume; increased Cardiac Output; increase in Systolic Blood Pressure (SBP).
AT-2 will also cause arteriolar vasoconstriction; results in blood retained in arterial tree during diastole; increased blood pressure during diastole = Increased Diastolic Blood Pressure (DBP).
AT-2’s action on Zona Glomerulosa (ZG) in Adrenal Cortex; releases Aldosterone.

♬ Ain't nothin' gonna break my stride, nobody gonna slow me down, oh no,
I got to keep blood moving! ♬ Today's #ClinicalCuts is all about the renin-angiotensin-aldosterone system, which helps keep blood movin'.
The main job of the cardiovascular system is to keep the blood moving, and to help facilitate that, blood pressure and other critical functions are kept under tight control. A major way the body does that is through a set of hormones that make up the renin-angiotensin-aldosterone system.
Renin is an enzyme that gets into the plasma and looks for its primary substrate, angiotensinogen.
Angiotensinogen is a large protein made up of over 400 amino acids that’s produced by the liver and is always hanging out in the blood.
When they meet up, renin cleaves off a huge chunk of the angiotensinogen protein, leaving behind a tiny fragment called Angiotensin I that’s just 10 amino acids long – a bit like a tiny pearl found within a giant oyster!
