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: registerednursern.creator-spr...
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.
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.

[@elysenelson3811]

Sometimes, I sit in front of my books trying to make my brain re-understand concepts. Other times, I remember you make amazing videos and I just wasted a whole day on something you helped me re-learn in 10 minutes 🙃.

[@zombiebean6191]

So true 🥲 I spent so long tryna understand what my lecturer was talking about RAAS 😅

[@copperlight]

Only the BEST RAAS system video over made....and I’ve watched a few 💐

[@Gabtistic]

I have a test tomorrow and this saved my life I was so confused at this

[@jacobparker7920]

Sara! I passed my NCLEX RN February 8th and my wife started her nursing prerequisites in January. Now I’m showing her your videos as she asks questions 😂. Thank you so much.

[@DeniseRene407]

Hi Nurse Sarah! Your videos got me through nursing school as well as the NCLEX. I recently accepted a position as a dialysis RN and I’m back watching your videos to brush up on the renal system. I’m pretty sure I’m going to be watching your videos all through my nursing career. 🙂 Thank you for all that you do!

[@sue1416]

who helps you through nursing school ? is it your dog? is it your family ? is it your classmate? is it your significant other? No, it's Sara from Registered Nurse RN.

[@virginiaperello2958]

Amazing, concise, eloquent! Dental student over here!

[@6bblsixpack]

Hi Sarah, I would like to say thank you so much for all your help. All your videos helped me tremendously with my review. I am a BSN RN from the Philippines. I have been out of school for more than 10yrs and last week I challenged my NCLEX RN exam for the first try and passed it in 75 questions! Next month I'm going to start my orientation in a BSN RN position and I am so excited. Thank you so much and I will continue to watch all your videos. God bless you Sarah and your family for helping all the nursing students around the world!

[@RegisteredNurseRN]

Hello! I just wanted to say CONGRATULATIONS on passing NCLEX. Thank you for studying with me. I'm very honored to help out a fellow nurse from the Philippines. I wish you the best in your career and may God richly bless you in your nursing career. Thank you for taking the time to leave this comment 💜💜💜💜

[@dsolomon]

Your videos are a lifesaver. I get tired of trying to learn by staring at my textbooks, and your videos really make it easier for me to learn.

[@May-kg6wj]

Sarah, May God bless you for all the work you and your husband put into these videos and your website. You were a key part of my success in nursing school and also the NCLEX. Thank you again!🙏🏾💕

[@greciagarcia959]

Hi Sarah; a future nutritionist from Mexico here 👋🏽, just to say thank you, this video was so helpful to recapping RAAS. 😃

[@Crissy868]

Currently preparing for final exams and your videos are really helpful. Keep up the amazing work. If i may, I'd like to see more videos on medication. Maybe you can group them according to class like antibiotics, antihypertensives etc. Also a video on crash cart medication would be nice. Thank you 😁

[@MrJimmy-ox7fq]

Another great video by a very intelligent and gifted young lady; I'm and RN but Nurse Sarah's presentations never get old and I always pick up something valuable to further my understanding of the subject matter. Keep up the good work!
