everyone is med school, at some point, tests their understanding of the material or hears the voice of their professors in their brain even when they're sleeping cause they've studies 12-14 hours straight, I had that happen to me with Ninja nerd videos & Zach's voice & Anki makes me test my understanding even in sleep/ light sleep. Zach- you're the best at explaining things to a level that they actually make sense & you follow through with every concept and it's collateral context in it's entirety, which most professors fail at. I cannot thank you enough, for helping me detangle the jumbled neuronal circuitry for so much of the material that professors & textbooks only rally jumble further. So Zach + boards & Beyond + pathoma + Drawittoknowit + silver thorn textbook + some Anki are so much of my life lately. (I wish professors lecture notes sufficed, but they just simply don't even though my school had some really stellar profs. I am obsessive I have to understand things logically, so I don't have to do explicit memorization.
You explained this concept better than my medical school professors can. It's shocking that you covered more clinical correlates on this topic than we were given.
This was...beautiful. I've had 3 different professors try to explain this material, and I got the basics but nowhere near a solid understanding. And you fixed it! You put it into English, and I get it now! I can't wait to tell my study group! And my professor!!!! Thank you! Big test tomorrow, and I'm no longer worried!!
So adorable the way u make faces for every cell and which makes me don't forget the things I can just keep listening the whole day and still won't be bored
thank you Ninja Nerd from the bottom of my heart! Your content is 100X better than the lectures are uni! you are truly amazing and god bless! if I come across any fortune I will donate a proportion to you :>
Really it's amazing chanell with amazing teacher thank u so much you helped me and many people to understand any something we need...This channel it's a gift for all medicine student thank u so much i can't believe how this channel not have a lot subscribes u deserve a lot❤❤❤❤❤❤
Can you do an updated video adding how the endothelial glycocalyx layer influences the change in pressures and leads to the lymphatics taking up all the fluid from the interstitial space?
Zach i think the osmotic pressure on the venule side of the capillary must be higher because we lost water making the blood plasma more concentrated so the osmolarity increases. Therefore i think we should be having a higher osmotic pressure on the venule side of the capillary. i might be wrong though u can correct me.
Congratulations nerdy ninja I always accompanied your videos and I have left well thank you so much for that I have basic notions of English that help me follow you I wish you courage and keep making more videos like this and I would like to take the opportunity to suggest you to make more videos of physiopathology i live in africa in the democratic republic of the congo a francophono country thanks and congratulations for the 1 M views and you can count on that we will always be supporting you
Thank you so much for this explanation. But Kindly answer one question of mine from this video You said that when MAP goes up, vasoconstriction occurs to to reduce blood flow. In your videos related to blood pressure, you said that b.p goes up when vasoconstriction occurs bcz of increased resistance. Is there a difference between MAP and b.p? PLEASE PLEASE SORT OUT MY CONFUSION. I WILL FOREVER BE GRATEFUL. BEST REGARDS
He said in his blood pressure videos that BP = MAP-CVP where MAP= Mean Arterial Pressure CVP= Central Venous Pressure Since CVP is very less we neglect it so it can be said MAP is appropriately equal to BP
Please don't take this the wrong way, you still explained this topic better than my med school professors, however for constructive criticism i felt that this video was one of the harder ones to follow. I think because you jumped all over the board. Anyways still thank you, and cant wait for your website launch and will absolutely get myself some ninja nerd merch!
Thanks for this great explanation, I have just one question, when the sympathetic system works does it close the arterioles part or venules part in skin and ig track?,, I got confused a little because the explanation was on the venules side, thanks another time ❤️
Arterial vasoconstriction causes the velocity of blood to increase, subsequently increasing the kinetic/mechanical energy. According to the law of energy conservation, potential energy carried by the blood is decreased when an increase in kinetic energy takes place. Decreasing potential energy =>decrease in hydrostatic pressure (since hydrostatic pressure of force exerted by blood on arterial walls) Hope that answered your question!
That a low MAP responds with vasodilation and a high MAP responds with vasoconstriction seems backwards to me. Please help me understand. I LOVE your videos.

I can't believe that you only have 6K viewers.. YOU ARE GREAT thank you so so mcuh!!!
So adorable the way u make faces for every cell and which makes me don't forget the things I can just keep listening the whole day and still won't be bored
You make every concept crystal clear! Thank you for this initiative! Keep shining!
Subtitles are absent in this video😞

This is the best content on UA-cam. Thank you for all
You are my teacher, I respect you a lot, if I ever meet you in life, I will kiss your hands 🥺🥺
Brilliant teaching method covering much more clinical corelations uh explain much better than my professor
Super helpful! Got my first physiology test tomorrow! Wish me luck :)
Good luck
Awesome explanation sir...love from Tamil Nadu , India...tq so much sir
thank you Ninja Nerd you making may days fruitful. my med university failed to teach me in a proper way.
Where can we get more Teachers like you?
- Schphincter -
ya'll hear him say it
So helpful! Thank you for all of your diligence in presenting these videos 😊
Really it's amazing chanell with amazing teacher thank u so much you helped me and many people to understand any something we need...This channel it's a gift for all medicine student thank u so much i can't believe how this channel not have a lot subscribes u deserve a lot❤❤❤❤❤❤
If anyone else if here to learn about local control of blood flow, he starts talking about it at 0:24:00 !!
Can you do an updated video adding how the endothelial glycocalyx layer influences the change in pressures and leads to the lymphatics taking up all the fluid from the interstitial space?
Thanks you so much 💗. God bless you, physiology is flowing because of ninja nerd med

Your good with giving examples to learning styles
im gonna have to put your name in the foot notes of my dvm diploma

Wara Qasim you can measure mean arterial pressure using blood pressure
He said in his blood pressure videos that BP = MAP-CVP where MAP= Mean Arterial Pressure
CVP= Central Venous Pressure
Since CVP is very less we neglect it so it can be said MAP is appropriately equal to BP
So freaking cute how Zach says sphincter
Thank you for your effort.
You are a good man!!
Thank you. You teach better than med school teachers. :)
Much better
God bless you for this bro! helped me greatly with this video.
"shsphincter" is my favorite part of this video
Please don't take this the wrong way, you still explained this topic better than my med school professors, however for constructive criticism i felt that this video was one of the harder ones to follow.

Thanks ninja.....it helps a lot.
God bless you. Thank u so much for ur efforts 🥺🙏💛⭐️
Please do a video based on edema
Thanks for this great explanation, I have just one question, when the sympathetic system works does it close the arterioles part or venules part in skin and ig track?,, I got confused a little because the explanation was on the venules side, thanks another time ❤️
THANKYOU SO MUCH FOR THIS .. GOD BLESS YOU
hi, can i ask a question, why does arterial vasoconstriction causes an decrease in hydrostatic pressure ?
Arterial vasoconstriction causes the velocity of blood to increase, subsequently increasing the kinetic/mechanical energy. According to the law of energy conservation, potential energy carried by the blood is decreased when an increase in kinetic energy takes place. Decreasing potential energy =>decrease in hydrostatic pressure (since hydrostatic pressure of force exerted by blood on arterial walls)
Hope that answered your question!
You make everything so easy. Woahhhhh 😍🙌🏻
Thanks ❤
I so grateful to you
That a low MAP responds with vasodilation and a high MAP responds with vasoconstriction seems backwards to me. Please help me understand. I LOVE your videos.
Thank you
Excellent videos please make video on internal medicine!
Amazing!!
Great video bro!!! Greetings from Mexico
loved it
Thankyou so muchh.God bless youu..more power to you❤
Awesome help. Thanks
thanks
Hi, could you maybe make a lecture on glycocalyx? its really a loaded topic which I am struggling to grasp
Great lecture!
Thanks for making it easier
Super clear!
Happy to subscribe both here and patreon! You guys are the best of the best~!
Very knowledgeable❤
28:23 shldn't it be vasodilatation due to stimulation of baroreceptors? or is the constriction only in the blood vessels of brain ?
thank u
Thank you 🙏❤️
i owe u my life
Can anyone plz explain me why hydrostatic pressure of interstitial fluid does not change
Sir, plz do video on hemodynamics
Thank you very much
Just love you ! Thank you very much
Awesome video 🤩
Is regulation of capillary blood flow is similar with micro circulation
Could you add subtitles for this video? Many thanks
amazing work !!!!!!
Thank You So Much. You guys are the best!!!
Please is it metaarteriole or metarteriole?
Is regulation of capillary blood flow is similar to micro circulationn
Oh yeah, thanks so much
THE BEST IN THE WORLD
Good work
Awesome
*_Wow lecture_*
pls show all the whitebord at the end pls pls
