CO2 Transport | Carbon-di-oxide Transport | Respiratory Gas Exchange | Respiratory Physiology

✨In this video, I talk about the three ways Co2 gets transported in blood, between the tissues and the lungs (Dissolved, Bound to hemoglobin and as bicarbonate). I hope it helps!☀️

Thank you so much. 😊 Fortunately ,I’ve discovered this channel before my physiology final exam 😅

[@jongminlee9501]

Your drawings and explanations are very clear and so easy to understand. A lot of other videos on KZbin 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!

[@bytesizemed]

Which muck are you using???

[@ishanthosar1359]

👍🙏

[@sanomanjiro4352]

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 ?

[@codrut913]

[@Guest10101]

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%.

[@gowthamkrishnans8869]

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!!!
