far better than any of my teachers have ever explained it thanks
literally the BEST explanation of what happens in the blood buffer system both chemically, mechanism, and biologically. Thank you!!!!
I saw a comment asking about where the CO2 in the blood comes from and where it goes, so I thought I'd comment in case anyone else watching wants to know. CO2 is a waste product of glucose metabolism in cells and it accumulates in the tissues. When oxygen carried by hemoglobin (in red blood cells in plasma of blood) passes thru the body, it gets ejected at places where the CO2 is accumulated. But the CO2 accumulation itself doesn't trigger the release of oxygen. The CO2 actually enters the blood plasma and from there it enters red blood cells where its broken down into carbonic acid and then further into protons (H+) and bicarbonate. The increase in this proton (H+) concentration is what triggers the hemoglobin to release the oxygen that it's holding, into the tissue. After delivering the oxygen to the tissues, the red blood cell takes up the CO2 and the blood flow continues to the heart from where it will enter the lungs to be exhaled.
One of the best lectures I've seen on the subject.
Thanks for the RUclips videos! You talk about science the way people talk about movie twists. You’re so excited and passionate! It helps me see just how incredible our body is, all the things that have to happen in order for us to function!
SO helpful! I was having trouble understanding this in lecture and from the textbook, but the way you explained it made it easy to grasp. Thanks!
I stumbled upon your explanation and it was by far the most concise yet informative and detailed.
Thank you! thank you!
Really great explanation, far better than any other I have seen.
Clean, simple and makes sense.
Appreciate it very much!
Still can't believe you gave us so much information with only 1 picture, great work!
So well explained that even I as a non-native speaker could get it. Thank you!
Such a phenomenal explanation, the diagram was perfect and you simplified it all very easily. Thanks!
Your explanation of this process is great!
Thank you!!!
9 years later and it's still being used
While many videos explain the conversion of carbon dioxide in the red blood cell, this is the first I found that explains how the conversion is reversed in the alveoli. Thank you.
This is very helpful. Thank you so much!
Thank you! Very simple yet informative
This video made it seem so simple thank you for the help! Great explanation!
Great explanation thx really helped
Thank you so much, very clear explaination. I now understand the chloride shift and carbon dioxide transport! Better explaination than my teacher
Excellent job explaining this! Thanks
this was great! all of the other videos on this subject that I found on youtube can't match yours. this is the complete cycle from the tissue to the lungs, and no one else has talked about the whole cycle. thanks!
AndreaaaNS please do watch my video on transport of carbon dioxide ruclips.net/video/Sc-g6Ogg-RI/видео.html
What beautiful way to explain this process, thank you so much!!
this is the best way ive heard it explained! thank you
Thank you! This will help me with my final, you explained it easier than the book and my teacher combined.
Thank you very much, it made carbon dioxide transport easier to understand.
Great video! thank you so much!!
Thank you so much. You’re such a blessing
Amazing! Thank you so much, it finally makes sense
Awesome video! This helped so much more than my teacher did in lecture!!
Great video. Thank you!
that was ultra clear and helpful, many thanks
Just wonderful. Thank you
Very nicely done! Thanks!
Very spectacular Video, I really understand the entire mechanism, thanks a lot
Thank you so much very good explained and love your structure.👏🏻👏🏻👏🏻👏🏻
EXCELLENT VIDEO!
Thank you so much! For some reason it wasn’t clicking until I watched your video.
Super helpful! Thanks so much!
Man that was sick!
I have a feeling this topic is going to be the essay question on my final because my teacher talked a lot about this today. He made no sense at all. You explained this so well, thank you.
Thank you so much for this!
thankyou so much for this! i finally understood it after trying to get it for so long!! thank youu
Perfect explanation. Really helpful.
Thank you for this lecture man!
Thank you! Great video! Totally understand this now! :)
Thnku very much. The thumbnail itself suffice to know the mechanism. Thnks🙌🙌🙌love from india
such a good explanation!
Thank you so much! So helpful!
spectacular explanation. Thank you
Life saving video!! Thank you sir!!
this is fire flames thank you.
incredible explanation !!!
amazing explanation!
this was insanely helpful!! thank you sir
Thanks for this video. I want to study Respiratory Therapy and this will help me a lot.
a very good and helpful video 100 percent. thank you so much
That was fantastic!!!!!!!!!
First semester nursing school student here. great video :)
In the uk we have to do this at 16/17, it’s so difficult! Good luck with nursing school :)
This was very helpful, thank you.
This video basically saved my life 😅😅 ty tysm♥️♥️
I had this diagram in my CIE endorsed textbook and it wasn't that easy to understand and thought wasn't making any sense. After I watched your video it made it easy for me to understand the concept.
Great video!
very good explanation! Please make more videos with pictures. You helped me a lot during studying! ❤️
Thanks a lot , you've saved me 🙏
Great explanation. Thank You
so so so helpful. thank you!
thanks this was awesome
thank you very nice, appreciated
10\10
thnx for the additional informations❤
Can you comment on the difference between the hemoglobin buffer system vs the carbonic acid-bicarbonate buffer system?
Great job bro , jst awesome explaination man 🤩🤩
awesome!
it's 2 am and i have a bio exam tomorrow and i love you greg
Thank you so much!!
very helpful!
sorry to be ask so this is mean that hemoglobin is not specificly bind the co2 but it actually made it to bind H+? so what does bind the HCO3 in RBC ?
Great video bro!
This was so helpful
Why is deoxygenated Hb a better H+ buffer/proton acceptor than oxygenated Hb?
Is carbonic acid diffusion from the lymphatic system into the blood effective or does it happen at a fast rate? I saw somewhere where they said this happened very slowly.
Great👍👍👍👍
Awesome
awesome
Thank you.
Awesome..thank you so muchhh
very good
really helpful..thanks sir
Thank you for the easy explanation, mademy med physiology exam a lot easier
Thhhank you
U r excellent
Lmao. Been so many years after the med school and never knew since when I actually had this idea in my mind that acidosis is due to the lactic acid.. thanks. Well spent 8 minutes 😬
Thanks
thank u
Started breathing properly after this video
After we get the C02 from the working tissue cell, and its pulled into the RBC, where do we get the h2o from to turn it into carbonic acid? - do we just 'suck' it in from the high concentration of h2o in the blood plasma ?
Thanks for the video ! the rest made more sense then my text book !
Since the blood is a watery (aqueous) solution the water is always present and available for use in chemical reactions.
well !! but i have a doubt - what happens if bicarbonate is accumulated in RBC???????????????? is it burst??????
gr8 video..
Btw where is the pict you got? Reference plis
thanks very nice vedio
This helped alot
real talk please do watch my video on transport of carbon dioxide ruclips.net/video/Sc-g6Ogg-RI/видео.html
