Welldone ma RAAS: is a well known regulator of blood pressure and determinant of target-organ damage. It controls fluid and electrolyte balance through coordinated effects on the heart, blood vessels, and Kidneys.
Renin angiotesin system:It is internal hormonal interaction devised by the body system to maintain adequate blood pressure in case of blood loss or shock. Organs involved are kidneys and adrenal cortex
Thank you for the lecture ma..it’s well explanatory. The RAAS system consists of the Renin,Angiotensin,Aldosterone system. This is activated when there is low blood volume which may occur due to haemorrhage,postpartum haemorrhage and other conditions. Then the sympathetic nervous system stimulated the kidneys in the Juxta glomerrula cells to secrets RENIN. This activated Angiotensinogen in the liver,which produces the Angiotensin 1..then the ACE comes in which is the Angiotensin converting enzyme which will convert the angiotensin 1 to 2.this is found in the lungs,kidneys and the endothelium. Immediately after the conversion,The kidney,adrenal glands and the pituitary gland are been worked on. On the kidney,it retains sodium and water,on the adrenal cortex,it also retain sodium and water and decrease potassium,and on the pituitary glands it activates the anti diuretic hormone,the vasopressin..all this is just to retain water and sodium to increase blood pressure. Now,the the alpha blockers will inhibit that ACE.so that it won’t increase the blood pressure,and there won’t be vaso. constriction..without the ACE..blood pressure won’t be increased.

Have you been struggling with NCLEX be it LPN, RN, or CNA, have you taken the exam for more than once? Are you taking it for the first time? Do you have a too busy schedule to study? Get to Dr Needham for your NCLEX assistance. I’m so happy I finally passed my exams thanks to him. He’s got a magical qbank which will help you become a RN
RAAs mechanism- when the blood volume drops or blood flow to the kidney reduces, kidney produce an enzyme renin to the blood streams which help to covert plasma proteins angiotensinogen to angiotensin 1 and ACE convert angiotensin 1 to angiotensin 11 which is a potent vasoconstriction thereby increasing the blood pressure
The Renin-Angiotensin-Aldosterone System (RAAS) is a hormonal cascade critical for maintaining blood pressure, fluid, and electrolyte balance, as well as systemic vascular resistance. This system is activated in response to various physiological triggers, including low blood pressure, decreased sodium levels, or increased sympathetic nervous system activity. RAAS components are, Renin, Aldosterone, Angiotensin I, Angiotensin II etc.

RAAS mechnics:renin is released by kidneys in response to decreased blood volume or low blood pressure which converts angiotensin 1 is converted to angiotensin ll by ACE in the lungs, angiotensin ll causes blood vessels to constrict increasing blood pressure.
When blood volume is low as a result of haemorrhage this makes the blood pressure to falls, the Juxta glomerular cells of the kidneys release an enzyme renin into the bloodstream. As renin moves in the bloodstream as it gets to the liver it then reacts with an inactive enzyme angiotensinogen which is protein produce by the liver and convert it Angiotensin I by Angiotensin converting enzyme. Angiotensin I, which is inactive (doesn’t cause any effects), flows through the bloodstream and is split into pieces by angiotensin-converting enzyme (ACE) in the lungs and kidneys and convert it to angiotensin II, an active hormone. Angiotensin II causes the muscular walls of small arteries (arterioles) to constrict (narrow), which increases blood pressure. Angiotensin II also triggers the adrenal glands to release aldosterone and the pituitary gland to release antidiuretic hormone (ADH, or vasopressin). Together, aldosterone and ADH cause your kidneys to retain sodium. Aldosterone also causes the kidneys to release (excrete) potassium through the urine. The increase in sodium in the bloodstream causes water retention. This increases blood volume and blood pressure, thus completing the renin-angiotensin-aldosterone system.

Concept of RAAS The renin-angiotensin system (RAS) is one of the major control systems for blood pressure and fluid balance. The major biologically active hormone generated by this system, angiotensin (Ang) II, is produced by sequential cleavage of peptides derived from the substrate molecule angiotensinogen (Agt). The renin angiotensin aldosterone system is the system of hormones,protein, enzymes and reactions that regulate your blood pressure and blood volume on a long term basis. The major biological active hormone generated by the system, angiotensin (Ang)ii is produced by sequential cleavage of peptides derived from the substrate molecule angiotensinogen (Agt) PROCESS when there is reduction in blood flow, juxtaglomerular cells in the afferent arteriole will be stimulated and produce enzyme renin, Renin will act with Alpha globulin in blood to form angiotensin I Angiotensin I will act with unknown enzyme in the lungs to form angiotensin Il (vasoconstrictor) angiotensin Il will stimulate the adrenal cortex to produce aldosterone Aldosterone will act on the kidney tubule to increase its permeability to sodium salt leading to increase in osmotic pressure of the blood then water balance will start because they work hand in hand.

when there is reduction in blood flow, juxtaglomerular cells in the afferent arteriole will be stimulated and produce enzyme renin,
Renin will act with Alpha globulin in blood to form angiotensin I
Angiotensin I will act with unknown enzyme in the lungs to form angiotensin Il (vasoconstrictor) angiotensin Il will stimulate the adrenal cortex to produce aldosterone
Aldosterone will act on the kidney tubule to increase its permeability to sodium salt leading to increase in osmotic pressure of the blood then water balance will start because they work hand in hand.
