All systems in body have a safety factor. What is the safety factor in oxygen transport. Watch the above video and share your thoughts below

Hemoglobin acts as a buffer for tissue O2 that is it resists even slight change in tissue PO2 when O2 partial pressure in arterial blood rise or fall lets say when at high altitudes and compressed chamber as high 02 are damaging to the tissues😊..is that right?

[@atharvgupta5681]

Best videos of physiology in whole youtube.

[@PhysiologyOpen]

Thank you so much…do share with others

Best video on oxygen haemoglobin dissociation

[@PhysiologyOpen]

Thank you ❤️

Finally I got the Nazeeb Hussein version of India... U r really a gr8 teacher ma'am.

[@PhysiologyOpen]

Wow that’s a great compliment. Thank you so much

[@zqr444]

But dky this channel is underrated she finish the concept within few mins with great understanding

[@PhysiologyOpen]

Thank you so much 😊…I am just thankful that people are liking what I am doing

Thank you mam It helps me a lot for better understanding

My pleasure

Mam kindly add this video in play list of r.s , so that its easy to watch without searching

Ob is it missing from there? Thanks for informing. I will add

So when we say that venous blood is 75% saturated of oxygen does it mean that in each one blood cell 75% of total hemoglobin molecule are fully saturated and 25% are empty ? Or it means that in one red blood cell all hemoglobin molecules contain o2 but each one carries 3 molecules of o2(75% of site ) ?? I hope you clarify this to me

[@PhysiologyOpen]

We don’t say for each Hb, rather for a sample of blood. Because from tissues Hb will become more deoxygenated , while less in some depending on their metabolic activity. So collectively we say that

​@@PhysiologyOpenhi ma'am I have a doubt. During left shift of curve affinity for oxygen increases then how will the oxygen unload in the tissue? Since haemoglobin has more affinity towards oxygen.

as always thank you so much for wishes. wish the same for you

You deserve millions of subscribes ma'am...... Simply awesome ❤️😊... Lots of love and respect from tamilnadu 💥🤩

[@biologywithbiswajit5]

Ma'am can u please explain the role of BPG in details? How its influencing dissociation exactly?

[@PhysiologyOpen]

It binds with beta chain and reduces oxygen affinity of Hb. Fet Hb does not has beta chain , hence has high affinity for oxygen

[@biologywithbiswajit5]

@@PhysiologyOpen thank you very much ma'am. Does the curve keep shifting left and right through the day or it's constant?

[@PhysiologyOpen]

@biologywithbiswajit5 it keeps shifting everywhere in every tissue depending on the conditions locally

[@narasimha7870]

Mam in carbon monoxide poisoning , wat is mechanism by which it prevent release of O2 bound to Hb?? Thank you mam 🙏

[@PhysiologyOpen]

Any change in dissociation occurs because of change in affinity
