A point I’m needing clarification on is this: if CO2 is elevated, it stimulates chemoreceptors and is blown off. But an elevation in CO2 will also shift the equation to the right? So which happens first and/or predominantly? The two concepts seem contradictory, but I know there is a piece I must be missing. Thank you.
It is an equilibrium where not all added CO2 will react to form H and HCO3 - it will just shift the equilibrium (as buffers do). So there will still be an increased P_CO2 stimulating chemoreceptors
Hi, thank you for the video! Just wanted to add something , the chemoreceptors are sensitive to the H+ , because the co2 in reaction with water in the CSF in the end (according to the formula) makes HCO3- and H+. I don't want to be petty, but I had to search more and more about the topic , because in my notes it was written that the chemoreceptors respond to H+ and from your video , at least the way I understood it, that they do not respond to H+ but only to co2
This video is really good and explains the respiratory buffer system well, awesome stuff!
Please make more videos... your teaching is really helpful. THANK YOU FOR THIS VIDEO.
This is just superb! Thank you
now I am cear concept about respiratory buffer system......thanks a lot.....

Thanks very much sir ...it was a great explanation ...it made my day...once again thanks a lot.
AMAIZZZZZING 😍thank u very much. keep up plz because your explanations is amazing .
Make video in digestive system physiology 💖💖💖💖💖

You can see it described here, under pulmonary physiology: www.sciencedirect.com/topics/neuroscience/central-chemoreceptors
It was very helpful... Thank you
well done. Thanks
thanks very much
Thanks!
Thanks
