Bohr effect vs. Haldane effect | Human anatomy and physiology | Health & Medicine | Khan Academy

Take a close look at how some friendly competition for Hemoglobin allows the body to more efficiently move oxygen and carbon Dioxide around. Rishi is a pediatric infectious disease physician and works at Khan Academy. Created by Rishi Desai.

Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

God bless you. There are only a handful of people who can teach like u can. Mashallah

[khanacademymedicine]

You might like the Double Bohr effect as well. Pretty neat phenomenon...

[stevengunther]

Can't say it in better Words than John Michael. You Sir, are a brilliant teacher and you just helped a medicine student from Germany to pass the first (and most feared) part of his finals. Thank you so much!

[danfonta]

Praise God that I found you!!! I can now understand what's going on in class!

[StraightRocketFuel]

Love your videos! I'm in medical school and every time I see the Khan Academy I instantly get excited because I know you guys will explain it clearly and concisely

[khanacademymedicine]

You're welcome...We will be getting into Double Bohr soon! =)

[kyeremak]

It makes so much sense on a detailed level now. Thank you.

[lernikshirvanian]

I wish my teacher could explain just like you. EXCELLENT!

[ShaistaC]

This was great! Thank you.

Just one thing I don't quite understand... for the Haldane Effect, its a straight line. The slope of the line decreases. Doesn't that cause the amount of CO2 in the thighs to change as well as in the lungs? Why are you able to compare the point for thigh on the blue line (without the Haldane Effect) to the point for lungs on the purple line which includes the Haldane Effect?

[yunchoi]

Wow, this is an excellent explanation!!!! I was very confused about these two concepts but now I totally understand. Thank you very much!

[SiberianHuskyF]

My lecturer somehow explained it in a way that I thought the two weren't even related. Thanks for clearing things up.

[candyg]

Thanks for making the Bohr effect and Haldane effect so easy to understand :)

[fuzzi]

This concept has been an re-occuring issue for me in respiratory phys. This video cleared up my confusion. Thanks!!

[justinoh]

Thank you so much for the great explanation! I'm not sure if someone has already asked you this but I was wondering what kind of equipment you are using to both record and draw out your explanations? Thank you for your time and I hope to hear from you soon.

[TheHadesShade]

this explanation is a lot better than the one my teacher gave me! Thanks for explaining! :D

[obliviousdave]

One of the best revision videos I have ever seen. Cheers!

[rimeln]

i love khan academy much! like i have sooo much love for you guys!! first  you helped me ace my a levels and now you're making uni soo much more easier and enjoyable for me <3 may God bless you

[MirandaTwentySeven]

This is the best physiology video I’ve seen in my entire life and will definitely help in my upcoming oral exam, wow.

[jeffersonhunter]

The difference between the oxygen content delivered (just after leaving the lungs) and the oxygen content after tissue metabolism does not equal O2 delivery, it equals o2 consumption or demand (Vo2).Am I confused?

Gracias por este vídeo! me ha servido de mucho!
