OMG!!!! I only have a few more weeks of Human Anatomy and Physiology II and I am so MAD I just found you!!! You were here when I started Anatomy I and I didn't even know it. You have such a flow and easy way to follow each body system etc., Although I am just so mad I missed you for so long, thank you for being here now at least! THANK YOU!!!!
Hey Jenn! You're very welcome! Glad you're finding the videos helpful, and good luck with the last few weeks of your A&P class. Also, thanks for the support on Patreon!
Excellent video, thank God I know English! By far the best explanation I've heard, you're great. Greetings from Spain, you've probably saved my med school exams :)
Great video, your teaching style is so engaging and comprehensive. The labelling exercise at the end is a beautiful touch. Really happy I've found your channel, no doubt they'll be helping me through my Osteopathic degree for the next 4 years!!
Learning and retention are all about connection to the content. WOW. For whatever reason, your visual outline w/ a concise explanation finally brought it home. Thanks...from the bottom of my kidneys !!
I’m an NP student who just started a nephrology rotation. This and your nephron video BY FAR are the BEST resources I’ve seen that capture and explain all the essentials of this fascinating and complex system! I’ve subscribed and intend to use your videos to supplement my education as well as refer your channel to others. THANK YOU THANK YOU!!!
Wow!! Fantastic explanation. I can't still understand why I found this concept difficult back in Medical school. The stuffs keep getting easier. Thanks for the superb explanations
I just spent an hour re reading my textbook trying to figure this out with no luck. Watched this video and completely understand it. Thank you Siebert Science, you are an amazing teacher!
Studying for the MCAT makes you feel like you can never spend too long on one thing. I didn't really fully get the RAAS from a couple of videos I watched but figured I'd just wing it with the knowledge I had. Finally decided I really needed to get it down and this is the first time it actually stuck with me. Thanks a million man.
I have been self-studying my A&P II course based on just the textbook and my professor’s ppt slides because the lecture weren’t helpful. If you were to be my professor, my A&P II course would be so much better and easier to learn, especially for someone like me who is a visual learner. These picture illustrations and side by side explanations are amazing!
Hey I have a question, wouldnt vasoconstriction of afferent arteriole decrease blood flow into glomerulus therefore decreasing pressure, which would decrease GFR which is a good thing because we have a low blood volume so we want to keep as much volume within the blood
Thank you!!- quick question, since you mention that this system is about low levels of Na+ if there was a high intake of sodium by the human, like eating salty meals- would this system cease? as in stop the stimulation of aldosterone to prevent reabsorption of Na+ into the blood stream and allow it for secrection into the urinary system.
Thank you for your great video. Making a very difficult concept so easy. I checked the first aid, aldosterone only affects the ENAC and NA.K PUMP in collecting tubules not DCT .is it correct?
Thank you , better than lecture 2hrs in class
Correct!
Couldn't agree more 😊
Agree
agree
This guy actually knows how to teach... Thank you sir
20 minutes of this has saved me hours of studying. Thank you!

I’m 50, no science background, a nurse student, it’s easy to follow, thank you very much.
Excellent video, thank God I know English! By far the best explanation I've heard, you're great. Greetings from Spain, you've probably saved my med school exams :)
You’re literally the best teacher ever…. Thank you!!

I'm so happy that I have found you're videos!! You are making my anatomy and physiology classes much easier to study for!
Love your videos and I especially appreciate how clean and well thought out your diagrams are! Thank you so much for your work.
Mr Siebert, you are AMAZING!!! I was so confused before watching your video. Now it’s crystal clear!! Thank you soooooo much!!!!!
Impeccable teaching skills. I really liked the concept of dividing the homeostatic process into 4; stimuli, sensors, intergration and effectors
Your videos have made me understand concepts I have long ago struggled to comprehend. Thank you very much!
i cannot even explain how amazing you are at explaining this. THANK YOU SO MUCHHHHHHHH

You make it so easy to understand the whole process of RAAS. Thanks a lot!!
You're so welcome!
Your explanations are top tier!! Just what I needed before an exam. Thank you!!!
this is ACTUALLY the first time i actually understand this mechanism after struggling so much omg! tysm for the vid!!
You literally saved me Sir...!
Your concepts are way more clear than I had imagined. Well explained. Love from India.❤
Thank you so much. Great help Sir. It is people like you that makes the world a tolerable place to live,
If ever there was an outstanding description of a relatively difficult subject this must be it Thank you so much

Such an amazing explanation of the RAAS!!!! Kudos and thank you!
You are amazing please go more in detail for others topics. You saved me hours of studying thanks a lot. Please please go more in details
RAAS is the most complex part of my A&P class so far, but thank you so much for your videos. Will probably have to watch this one a few times.
This video and the nephron video saved my butt today on my Systems Phys exam! You make it so easy to understand and remember. THANK YOU SO MUCH 😭😭😭
Thank you so much! I love your teaching style, it makes everything so easy to understand!!! THANK YOU!!
You are the best at teaching. You made things so easy to understand and learn. Thank you.
you singlehandedly answered all my questions from a whole semester of anatomy
16:03
action of angiotensin II is contraction of mesangial cells resulting in (decrease) of the GFR not increase.
Correct me if I'm wrong..
wow, I'm so happy and grateful for my course. I'm having fun with A&P it's like a puzzle 😮
Thank you. This was the best explanation I've seen. Very clear & helpful.
Thank you for explaining it really well and for easier to understand you’re a really helpful to us students.❤
Thank you so much for this video! Your content makes these subjects very easy to understand and also very fun! Makes me enjoy learning these things.
Amazing! I have hyperaldosteronism and this gave me a deeper understanding. Wish you were my dr.!!
You ARE THE MANN!!!!! I finally understand RAAS. Thank you :)
Thank you so much! You are an awesome teacher! I now understand somthing I've been reading about for a week. Thank you!
This video could not explain this process any better! Thank you!!
:)
Whoaaaaa you are the best. You teach better than my Prof
Bravo!!!
Thank you so much for explicitly breaking down all these.❤❤❤
Thank you so so much for drawing ALL the visuals 🫢AND explaining. They are very helpful!
I like the way you teaching with step by step which much easier to catch up and thanks

Thank you very much. The way you explain things is really interesting and captivating.
This lecture is very lively and interesting compared to this in school. Thank you so much
your videos are very easy to understand. I had A in both anatomy and physiology I last semester. thank you so much
This explanation iss the best that I have come across so far. Thank you so much!
The way you explain this is amazing, thanks 🎉
You're very welcome!
Never understood better! Thanks a lot!!❤
Never understood this until NOW, Thank u so much❤
You taught this better than my prof!!
thank you so much this helped a lot. i wish you and your family a merry christmas and great holidays :)
You changed my understanding...❤❤
I like your video’s, simple and easy to understand. Can you do lymphatic system?
Thanks! I'll add lymphatic system to my list of videos to make!
You are such a good teacher!!!! Thank you.
Thank you very much! This video explanation is extremely helpful.
This review was excellent.
Bril lecture.
Angiotensin II has an effect on both afferent and efferent arteriole but it mainly constricts the efferent to maintain the GFR.
Beautifully explained ❤
You have a gift of explaining things 😍🤗😊 ty
Love your videos! Thank you so much for making them.❤
THIS HELPED ME SO MUCH, thank youuu😊
angiotensin 2 constricts mainly efferent arterioles, not afferent. In that way the pressure in the glomerulus increases
best lecture, please continue and make more videos. you are the best.
Could you link exercise to RAA system. I’m curious as to the lungs and neuromuscular contributions
YOU DID AN AMAZONG JOB. I UNDERSTAND IT ALOT MORE THANK YOU
Glad it helped!
sooooooo grateful for your channel. Thank you!!!
5:40- my understanding was angiotensinogen isn't considered a hormone, is that right?
Fabulous explanation! I loved all contents in your video, well explained for us to understand easily! Thank you for making such a good video :)
You naturally intelligent sir , you make physiology of the kidney to me to very simple. Easy to understand. Thks
Thank you so much! you are an A&P SAINT!
Wonderful video and thank you for producing.
Wow this is good, well expanded
Thank you soo much this is such an amazing resource and you're such a great teacher!!!
Man, you are amazing.
Excellent video brother, Thank you.

just passed the TEAS thx dude!
The macula densa are in the DCT? I thought the DCT was on the other side of the Loop of Henle?
i’m just learning this in class! thank you!
Awesome! You're welcome!
I'm just curious, what level of class is it for? (high school, undergrad, med school, other?)
@@SiebertScience undergrad
