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 YouTube 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!

[airotkiv]

So well explained that even I as a non-native speaker could get it. Thank you!

[joseheli]

I stumbled upon your explanation and it was by far the most concise yet informative and detailed.

[romeolhk]

Still can't believe you gave us so much information with only 1 picture, great work!

[zsebi]

Thank you! thank you!
Really great explanation, far better than any other I have seen.
Clean, simple and makes sense.
Appreciate it very much!

Such a phenomenal explanation, the diagram was perfect and you simplified it all very easily. Thanks!

[AndreaaaNS]

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!

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.

Your explanation of this process is great!
Thank you!!!

9 years later and it's still being used <3 thank you for this

[wetsponge]

This video made it seem so simple thank you for the help! Great explanation!

[UrpinionDoesntCount]

this is the best way ive heard it explained! thank you

[KM-zetr]

Thank you! Very simple yet informative
