Your drawings and explanations are very clear and so easy to understand. A lot of other videos on UA-cam only deals with short summaries but I really like how you include the in-depth material that I need :) You saved my life studying for medical physiology. I hope you keep on making videos for other physiology topics as well because god knows I need it!
I think the explanation from 2:26 to 2:39 may be incorrect. The Haldane effect actually occurs at the level of the alveoli, where the binding of O₂ to hemoglobin decreases its affinity for CO₂, causing CO₂ to be released from the blood into the alveoli. In the mentioned timestamp, you've stated the opposite- "removal of O2 from hemoglobin, increase hb affinity for co2 and that's the Haldane effect"
thank you so much for this video! As a nursing student this video was well made and easy to understand with such a complicated topic!! keep up the great work!! ❤️
Why Bicarbonate ion diffuse out from red blood cell to maintain the electrochemical in red blood cell Cl- then diffuse into red blood cell, both bicarbonate ion and Cl- are same charges , so why does bicarbonate ion diffuse out in the first place ?
In red blood cells, the movement of bicarbonate ions (HCO₃⁻) and chloride ions (Cl⁻) is a crucial part of the process called the chloride shift, or Hamburger phenomenon. Here’s how it works: 1. CO₂ Conversion: In tissues, carbon dioxide (CO₂) enters red blood cells and is converted to carbonic acid (H₂CO₃) by the enzyme carbonic anhydrase. Carbonic acid then quickly dissociates into hydrogen ions (H⁺) and bicarbonate ions (HCO₃⁻). 2. Bicarbonate Diffusion: Bicarbonate ions (HCO₃⁻), now in higher concentration inside the red blood cell, start to diffuse out of the cell into the plasma to maintain balance in the blood pH. 3. Chloride Shift: To maintain electrical neutrality, chloride ions (Cl⁻) diffuse into the red blood cell from the plasma as bicarbonate ions leave. This exchange of anions ensures that the cell's charge balance is maintained even though ions are moving in and out. Although bicarbonate and chloride have the same negative charge, bicarbonate’s tendency to diffuse out first is driven by concentration gradients created as CO₂ is converted into bicarbonate inside the red blood cell. This exchange is not purely based on charge but also on the chemical gradients that favor bicarbonate exiting and chloride entering.
I'm honestly nowhere near even average intelligence. I want to state this before I continue with this comment. How does that 1% of carbon dioxide transport? Does it not? I'm concerned about the 1%.
CO2 is transported in 3 forms 1. CO2 directly dissolved in blood (5-10%) 2. As Bicarbonate in blood (70%) 3. As Carbon Dioxide directly bound to hemoglobin along with free amino group (NH2) (20%) As there are rounded of figures, the it should add up! Hope that helps!!!

Thank you so much! I appreciate the support! I'm glad my videos are helping you and there are definitely more to come😊
you clearly explain the transport of carbon dioxide in the form of bicarbonate ion so nice of you
..😢
the most underrarted channel on youtube!! simple clear explanation of complexe mecanismes in just 5 minutes.. genius
please keep making videos.
Thank you so much. 😊
Fortunately ,I’ve discovered this channel before my physiology final exam 😅

The video was short and brief.
Loved it.
Just keep making these videos, never stops. My teaching method in wonderful
Such a perfect video. Explains everything in a good depth, with animations that help the understanding
thank you so much for this video! As a nursing student this video was well made and easy to understand with such a complicated topic!! keep up the great work!! ❤️
I have watched every video on this topic and for the length of video, yours is the best!
Yours way of explaination is osm and very helpful for me and people like me . Thank you so much ❤ keep it up 👍
Understood everything perfectly! Thank you so much ❤
Love from Pakistan 😍 best teacher ever. ❤️
much better than 10 pages in my textbook :)))). Thanks a lot
