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

[@atharvgupta5681]

Best videos of physiology in whole youtube.

[@PhysiologyOpen]

Thank you so much…do share with others

[@biologywithbiswajit5]

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

[@biologywithbiswajit5]

Best video on oxygen haemoglobin dissociation

[@PhysiologyOpen]

Thank you ❤️

[@DrGHaris]

Grt video marvellous teaching

[@PhysiologyOpen]

Thanks 😊

Great Great and simply great...stay safe and stay blessed madam amidst good health happiness and success forever

[@PhysiologyOpen]

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 💥🤩

Thank you mam It helps me a lot for better understanding

[@PhysiologyOpen]

My pleasure

Very beautiful explanation ☺️☺️☺️

[@PhysiologyOpen]

Thanks a lot 😊

[@ulagavishnu4457]

thanks a lot for this video mam..

[@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

[@kashibakashiba4137]

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

[@PhysiologyOpen]

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

[@PhysiologyOpen]

Guyton always....if difficult go for of course my notes at physiomed.winuall.com

@@PhysiologyOpen thank u mam 🙏🙏🙏.

[@chaimaasalhi9646]

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

[@chaimaasalhi9646]

@@PhysiologyOpen thank you so much ma'am 😊

[@PhysiologyOpen]

[@anuragnath8182]

​@@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.

[@ZainabTariqMahdi]

The source please?

[@PhysiologyOpen]

All my sources are basic Guyton Ganong…and that’s minimum…then I go for all reference books
