This guy is the only reason I'm getting through med school....lol. I just want to know who the 21 people are that didn't like the video!!!!!!!!! (probably faculty members seeing their jobs going away)
Zach, I'm a Term 1 medical student and I just want to stop by and tell you how much I appreciate all your videos. I'm on my last week of the first term and we have our CPR2 exam coming up and your videos have clarified so many points in their lectures. A year ago my father died from a massive pulmonary embolism. As you can imagine, its very difficult for me to listen to these concepts and understand just how much he went through during his final moments. He's my sole motivation for becoming a doctor. I hope I can make him proud in the years to come but as of right now I've been able to accomplish that thanks to you and your channel! I look forwards to watching many more of your videos throughout my medical school journey. Thanks again!!!
Thank you so much. I'm in dedicated right now studying for Step 1, and this is the first time I've ever understood ventilation and perfusion. Ever. I cannot thank you enough.
OMG!! This is absolutely fantastic!! If you understand the basic concept - like what you are explaining, you can never get lost anywhere in Respiratory Pathophysiology!! Thank You Very much!
This man is a genius he teaches and explains things that you didn't understand in your past physiology lecture in class. God richly bless🙏 your for passion and sincerity to let every student comprehend.
best teacher ever! seriously thank you for helping me get through my physio in the course of 6 weeks -_-...yes 6 weeks. I learn more from you then my professor so I stay home and study my chapters with ninja nerd. Thank you
+Breeann Barcelona wow! Thank you for the kind words they mean so much. You are a brave individual for taking a physiology course in six weeks. I hope these videos really helped and I wish you the best of luck in your future endeavors.
Ninja Nerd Science sir iam really thakfull for your teaching....earlier hardly i studied that toowith fear...afteri started watching ur videos,iam studying out ofjoy now sir
Respiratory Physiology has always been a nightmare for me to study until I came across your lectures. Thank you so much for taking the time to explain intricate information to such simplicity. Keep up the awesome work.👏👏👏
Wow! this is exremely wonderful. Thanks alot, you made this things very easy. Point of correction- The lower zones of the lung ventilate better than the upper zones and the middle zones have intermediate ventilation.
Im beginning to think the people who dislike this video are the professors who "teach" the subject but suck at explaining it. What a bunch of haters. You rock dude keep it up!
Hello u said that ventilation is better in the top(apex ) of the lung ,but actually it should be decreased bec all books said that lower zones of the lung ventilated better thant upper ,i wish u explain!! + ur the best in explaining physiology
Sir, you teach us from the root of the topics that i love... Sir can u make a video on chest x-ray..there are many lectures on xray but all are boring....
At time 27:30, you said that ventilation decreases from apex to base, but actually it increases from apex to base of the lung. Perfusion also increases from apex to base, but much more significantly that we have a lower V/Q at the base.
@@BlaackAnchor is it because at the end of expiration, the FRC at the apex area is more than the bottom, so the ventilation at the apex is considered lower?
I feel like you should have emphasized that the smooth muscle in the arterioles contracts and relaxes because capillaries dont have smooth muscle and so the illustration can be misleading.
wanted to let you know Ninja Nerd. you have helped me so much man. literally could not get this down until i watched your video a few times. working toward the Flight Paramedic Certification which, there are no classes to teach the material just a book. so just wanted to let you know. HUUUUGE Help!! couldn't have done it without you.
Untill i saw ur lectures for the God sake i really hate physiology Our lectures would say anything clearly They even don't knw wht rubish they were teaching us Ur excellent 💯 teacher U were helping all 1st yr students sooo much ☺thnk zach sir
There is an error: ventilation is higher at the base than at the apex because of increasing compliance. The V/Q ratio is biggest at the apex because at the apex: Q higher is relatively to V. V/Q ratio is lowest at the base because V is higher comparatively to Q.
I think this video is good but could have been better if you explained why 0.8 is so pertinent for the AVR. Also, presenting different diagnoses that change the ventilation and perfusion rate/amount and how the pathophysiology works. Thank you!
Hey Zach, great video but wouldn't V AND Q be greater at the base compared to the apex (~28:00)? Pa > Pv > PA in Zone 3 so arteriolar perfusion pressure leads to good blood flow. For Ventilation, alveoli at the base have higher compliance and we would see an increase in ventilation for Zone 3 as well. Overall the the increase in Q > V so V/Q is decreased even though both are increased
I've never seen someone teach with such passion and sincerity.. Thank you so much
I wish I could hire him as my own teacher
This guy is the only reason I'm getting through med school....lol. I just want to know who the 21 people are that didn't like the video!!!!!!!!! (probably faculty members seeing their jobs going away)
i was thinking the same thing!
😂😂😂👍👍👍👍
Real
he is great I actually enjoy his videos, I’m learning from videos he made like 7 years ago 😂

You guys are saving me a lot of heart ache with my pulmonary physiology lectures. Humble thanks! Your efforts are greatly appreciated!

First year veterinary student here and your channel has been a lifesaver for all my physiology courses, so I wanted to comment a big THANK YOU!!
This man is a genius he teaches and explains things that you didn't understand in your past physiology lecture in class. God richly bless🙏 your for passion and sincerity to let every student comprehend.
Words are useless to appreciate.Finding this channel was the best event in my entire life
I actually understand what you were teaching. Thank you so much for helping a difficult class in nursing school make sense
best teacher ever! seriously thank you for helping me get through my physio in the course of 6 weeks -_-...yes 6 weeks. I learn more from you then my professor so I stay home and study my chapters with ninja nerd. Thank you

Helping me get through CRNA school!!! This page is such a blessing
I’m a student nurse anesthetist. I wish my physiology course would just post your videos instead of their lectures. You’re awesome.
Holy moly he’s freakin’ good! Better at teaching than my instructors! He makes it so simple and straight to the point!
Idk why we humans after seen all these amazing things still believe there is no creator and it’s all just present
Subhan Allah❣️
YOU COME THROUGH EVERY SINGLE TIME OMG I APPRECIATE YOU SO MUCH
Zach, i'm in respiratory school and I got to tell you man you've saved my butt so many times with your videos. Thank you for your hard work!
I will be a RT student this summer any advice?
Respiratory Physiology has always been a nightmare for me to study until I came across your lectures. Thank you so much for taking the time to explain intricate information to such simplicity. Keep up the awesome work.👏👏👏
Wow! this is exremely wonderful. Thanks alot, you made this things very easy.
Point of correction- The lower zones of the lung ventilate better than the upper zones and the middle zones have
intermediate ventilation.
In addition ventilation perfusion ratio increases three times in the apex than in the base
But in that won't the v/q ratio be disturbed?Could u explain why u think ur point is right?
Im beginning to think the people who dislike this video are the professors who "teach" the subject but suck at explaining it. What a bunch of haters. You rock dude keep it up!
these videos have really helped in a wide range.
Always such great explanations! I am rewatching the pulmonary lectures and they make so much more sense.
Tomorrow I have an exam on all respiratory subjects and you are saving my life❤❤❤😢thank you sir.
Edit: my exam was so hard 💔
🥺🥺
U guys did it again men making my exams brighter i appreciate mates
the best channel for med students!!
WHAT ELSE TO SAY THEN: I LOVE STUDYING WITH NINJA NERD!! THANK YOU FOR HELPING ME BECOME A DENTIST :-)
Just Awesone .... I go into ecstasies whenever I watch your videos . It helps me alot in my medical studies . Thank you soooooo much💞💞💞💞💞❣😊
Thank you so much for this video, you're literally saving lives.
THANK YOU SO MUCH! I felt lost between my papers understanding nothing about respiratory physiology and you saved my life❤
Perfect videos for Respiratory Therapy school, thank you so much!
Your video was awesome!! I never comment on these things, but you deserved a response. Keep it up, Ninja Nerd!!! On my way to watch more.
Thanks you so much for the presentation on V/Q ratio .
It was amazing .
Great.
outstanding. cheers mate from Turkey,
you're saving lives i can say that !
You broke that down to the ground! Amazing Job!
you give the human body it's proper dues! love your videos. big thank you!
I am brazilian and this video helped me so much
Thank you so much for the video on V/Q. This is awesome.
This is some of the best content ever
You are a wonderful teacher! Thank You for helping me through pathophysiology
Thank you very for your lecture. It’s easier to understand than reading the book
He literally made it simple. Thankyou!
Thank youuuu so much our DR 💝💝💝💝💝💝💝💝💝💝💝💝💎💎💎💎💎💎💎💎💎💎💎💎💎🌼🌼🌼🌼🌼🌼🌼🌹🌹🌹🌹🌹🌹🌹🌹
Extremely perfect!
I really enjoyed it bro. Congratulations
Hello u said that ventilation is better in the top(apex ) of the lung ,but actually it should be decreased bec all books said that lower zones of the lung ventilated better thant upper ,i wish u explain!! + ur the best in explaining physiology
Yesni read the same
Sir, you teach us from the root of the topics that i love... Sir can u make a video on chest x-ray..there are many lectures on xray but all are boring....
You deserve all my respect ... thanks alot .... thanks again🌸🍃
best videos ever - actually makes learning this stuff, dare I say, FUN?!
This was so perfect and helpful in every way! one of my favorite videos on RUclips.
Thankyou for everything 🙏🙏
At time 27:30, you said that ventilation decreases from apex to base, but actually it increases from apex to base of the lung. Perfusion also increases from apex to base, but much more significantly that we have a lower V/Q at the base.
but shouldnt air goes against the direction of the gravity?
@@caidenlu we are talking about ventilation here, not just air. Thanks for your input....
@@BlaackAnchorbut isn't ventilation the movement of air? but i get youre right, just still got confused here about why
@@BlaackAnchor is it because at the end of expiration, the FRC at the apex area is more than the bottom, so the ventilation at the apex is considered lower?
@@caidenlu The ventilation is low because the cross sectional area (surface area) is low in the apex of the lungs
Thought yall were capping but this a game changer fr
I became a member and the extra notes are amazing thank you so much
Glad you’re enjoying it! 😀
Love this guy. Such a good teacher!
I feel like you should have emphasized that the smooth muscle in the arterioles contracts and relaxes because capillaries dont have smooth muscle and so the illustration can be misleading.
Elaborate
best teaching ever
what a conceptual lecture it was.....well done....more power to you...
your videos are so amazing. THANK YOU! THANK YOU! THANK YOU!
Best explanation ever ❤
I love your lectures! Clarifying my concepts now after completing my med school lol. I wish i had found your lectures earlier. Love from 🇵🇰
wanted to let you know Ninja Nerd. you have helped me so much man. literally could not get this down until i watched your video a few times. working toward the Flight Paramedic Certification which, there are no classes to teach the material just a book. so just wanted to let you know. HUUUUGE Help!! couldn't have done it without you.
Lots of love to you sir! You made this topic so much easier to understand 😀
Untill i saw ur lectures for the God sake i really hate physiology
Our lectures would say anything clearly
They even don't knw wht rubish they were teaching us
Ur excellent 💯 teacher
U were helping all 1st yr students sooo much ☺thnk zach sir
Thank you, Ninja Nerd. 💯
Mannnn you're the best and you're genius 😭♥️♥️ I really don't know how to thank you but you really help me in my studying.. ♥️ Hi from Iraq 🇮🇶
طلع دكاترة العراق كسر 😂
Wow great video Zach
Thank you for the best lecture video and they are understandable
You are just too much.Thank you so much for your help. God bless you.
Love and a great respect from india .....very passionate teacher u r....bdw I m also a biology teacher 😊😊😊
This is really wonderful
Thank you Ninja Nerd!
you are the best teacher ever!!
Zack you are king❤ much love from Sweden ❤
27:15 !Ventilation is higher at the base of the lungs (in an upright position) due to gravity pulling on lung tissue which increases pleural pressure!
Such a great effort Sir 🙌💯
Thanks alot for making it easy to understand ...
You’re brilliant!
Thank you professor God bless you❤
Good video pal. Very well explained. Thanks.
Ventilation increases from apex to the base. Please correct it ! Other than that ! A big fan ! Great job zack !
There is an error: ventilation is higher at the base than at the apex because of increasing compliance.
The V/Q ratio is biggest at the apex because at the apex: Q higher is relatively to V.
V/Q ratio is lowest at the base because V is higher comparatively to Q.
amazingly helpful
Check the description guys
you're a lifesave mater
all your lectures are excellent..thank you..could you please give lectures on Mechanical ventilation basics and breathing cercuits if possible.
Love these lectures 💕
Hey thanks for this video could you please assist and create a video on how an incentive spirometer works to prevent atelectasis?
Love your explanation 👏
You just save my life!!!
Thanks ❤
Great job! Thanks
Your amazing, excellent teacher! Thank you.
I think this video is good but could have been better if you explained why 0.8 is so pertinent for the AVR. Also, presenting different diagnoses that change the ventilation and perfusion rate/amount and how the pathophysiology works. Thank you!
Correction : ventilation and perfusion both is less in the apex of the lung
U deserve respect ...
This helped me so much !! Thank you.
U should explain how CO2 is causing bronchocontriction and dilatation... Keep it up
You're a godsend!
Hey Zach, great video but wouldn't V AND Q be greater at the base compared to the apex (~28:00)? Pa > Pv > PA in Zone 3 so arteriolar perfusion pressure leads to good blood flow. For Ventilation, alveoli at the base have higher compliance and we would see an increase in ventilation for Zone 3 as well.

You da real MVP
you're really the best
Never get bored
