- ✨This is the first in a three-part series on acid base physiology. The job of regulation is done by three systems. Buffers, the lungs and the kidneys. In this video, I talk about some of the basics of acids and bases, in addition to the role of buffers. I hope it helps!☀️

5 years into medical school and all these concepts where very disorganised in my head. Thank you so much.
oh my god so good u cleared my concepts about buffer mechanism thank you so much 💜💙
this is fantastic, thank you!
thank you so much for this succinct and straight to the point video
thank you so much!! your videos help me a lot.
Wow Thank you sooo much, this is exactly what I needed
I love this... ma'am can u plz upload pulmonary ventilation (resp. system)??🙏🙏
Awesome explanation 👍
tremendous explanation!
Thank you so much ma'am 😌 i gonna watch all your videos...i found it really helpful ☺️ thank you once again
Crisp explanation!😊
Thank you so much 💛
bro this is actually amazing
You are just phenomenal 😢❤where have you been all my life
Nice explanation 👌👌👍🏽
Thanks,amazing
Wow this is very good ❤
i really like your all lecture. please make more videos on usmle step 1 and step 2. thank you so much mam.
Amazing ❤️🔥
It's the best❤❤❤
Good video!
Our guru ,Suhas and vijay loves you ❤❤❤❤❤❤❤❤🎉🎉🎉🎉
amazinggg keep goingg
very helpful mam keepit up
Perfect. Which drawing program do you use? Thank you.
Thank you
The best video on biological buffers...
A small correction....it is Hasselbalch, not Hasselbach. Everything else was awesome...
Ty
Very well explanation but I find some little confusing at 2:51, in the part of co2 + h2o and carbonic anhydrase then it forms carbonic acid. Carbonic anhydrase is an enzyme and it speed up and dissociates the h2co3 into hco3 and h+
So?
A little confused by when you said , if we increase OH- , then if the balance shifts to the right. Even though more H+ is formed, there is also formation of more HCO- , so wouldn't that amount to no change ?
Hi! The kidneys work along with the lungs in regulation. From how I understand it, when the pH increases, the kidneys are going to keep the H+ ions while they get rid of more HCO3- ions. So they’re already removing the bicarbonate trying to bring the pH back up, and it compensates for the bicarb that’s being formed. I hope that was helpful! 😊
👍👍👍
Must be very nais
Thank you so much for your great video that help me alot! ❤️❤️
Can you please upload GIT EMBRYOLOGY... please
How can l gat this note
I'm in gen chem and was just looking for an explanation of buffers lmao
Please can anyone explain why pH changes with PCO2 changes, as from the equation H+ and HCO3- are produced at a 1:1 ratio, and given that HCO3- buffers any H+ that is produced, forming H2CO3, wouldn’t [H+] and pH stay the same? (Not saying this is true - this is my question and what I’m trying to understand!). How can H+ concentration change if for every single H+ that is produced there is also one HCO3- produced that would buffer it to form H2CO3?
Please I would be so grateful for an answer to this question, thank you so much!
I also have the same question?
.
this video is really poorly done.
