Good video.



[sneakybast3rd]

what happens to that 2% of non-converted oxygen? does it go through your bloodstream as air bubbles?

[moonsun786]

@sneakybast3rd Actually, less than 1.5% is dissolved in the blood plasma.

[Neroscot]

Please, do not smoke...!



[eranbw]

Wonderful clip by the way!!

[ben5073]

it would be cool to see this process at the atomic/molecular level

[DADHYAKSANTI]

thank you this video can be help me to understand

[SparklenShineStudios]

Great video!

[EsaChicana9151]

HEY DIS VIDEO HELPED ME ALOT....THANK U.....

[briebrigi]

it's good for students !!!!!

[klynn42066]

thanks for the CLEAR audio & great animation !

[smileysnowman24]

Is that your voice?



[klynn42066]

@smileysnowman24 ? 

[SukhovKonstantin]

Its good filme, please contact with me - konstantinvs@yandex.ru

[irawr3m0pandasi]

@SukhovKonstantin Really?

[kobrajesusreturns]

that was good but he talks too fast

[picaticatara]

true

[fulla92]

thanks for shearing it

[o2me2]

Fantastic video. Thank you for the valuable information.

[Gottfried2210]

PS: the oxygen doesn't actually dissolve into the blood, it diffuses past the capillaries from the alveoli, directly into the blood stream, where it binds to the haemoglobin. Oxygen is way too non - polar to be dissolved. Unless the temperature radically decreases (which it has not) or the pressure massively increases (which did not). So it is a highly improbable that such an event will occur.

[sebsonater]

@Gottfried2210 oxygen can and does dissolve into aqueous solution (dissolved oxygen levels are a measure of the health of lakes and streams)

2% of oxygen in the blood is unbound and dissolved in plasma

the remaining 98% is bound to hemoglobin

[suhad91]

thanx

u make it easy to understand

[Aboydebeat12]

I learned this in 3 lessosn, and i didn`t getted it, now in 3 min I know it,

thnx so much

[2jimmy21]

Thank you! Learned more in three minutes than an hour in class!

[ahlussunnahwj]

Aaargh... eyes!

TWICE.

[draotic]

u savd my life

god bless!

[GoldenBudgiesRule]

there is something about the guy's voice - it's just blah blah blah -

you don't suppose he is just hand reciting perfectly as opposed to knowledgeable soul with excited insight?? silly people don't know that all that hesitation voice waves and breathe pauses is what makes it so much easier to understand

[sxureedb]

Heme structure is wrong. It is attached to the protein via a histidine ligated to the iron, not these two 'sticks' that eminate from the edge of the heme. And what does "iron containing pigment" mean? Its the heme porphyrin structure that is the pigment NOT the iron!! Goes to show that you cannot entirely believe even professionally produced stuff like this. Otherwise not bad.

[cossmmynn665]

yeah... the graph's ok, but forgot to mention that both oxihemoglobin and carboxihemoglobin are unstable compounds, so the oxigen will be released into the tissues...oh and also the gas exchange in the lungs (O2 and CO2)

we die from prolonged exposure to carbon monoxide because the CO and the hemoglobin forms an stable compound, that doesn't "break up", so the gas exchange doesn't happen and the body will be deprived of oxigen, eventually pass out and die

sorry if i made any grammar mistakes

[muktid]

Thank you.

[pseudohippie55]

Just imagining the immense amount of Heme in your body as of right now is insane.

[NorwegianBastard]

@lostdreamz901 And I'm studying chiropractic; it's like medicine, only that you don't have to be THAT smart! xD

[NorwegianBastard]

@lostdreamz901 Yes, that is true - but the purpose of this video, I believe, is to explain the oxygen transport of the hemoglobin in an approach that is simple and short in order to enable better understanding for those who do not have a background education within healthcare professions, science or biology. The details, which you have a listed a few of in your comment, are available in various textbooks of physiology.

[smilesnblues]

needs to be more detailed

[NorwegianBastard]

@smilesnblues Read a book, then.

[smilesnblues]

@NorwegianBastard huh suggest me a good book then

[NorwegianBastard]

@smilesnblues Use Google and search 'oxygen transport, physiology, cardiovascular system, etc.'

[sammynick04]

very helpful! im taking the dreaded MCAS test 2morrow and i understand oxygen transportation now, thank you

[GandhiLover]

Very good for the focussed discussion of intended  instruction

[MultiYerick]

Thank you very much

[kevin271311]

this video doesn't make any sense to me.

[superspine113]

no fucking idea what he was talking about but looked SO AWSOME

[tricia618]

good video. thanks

[usefulstuf]

There is a problem with the color photos of the JFK limo in the Washington DC garage. The rear seat shows a RED blood smear.

That is a huge oxidation problem.

In this universe, during the time from the Elm St conspiracy murder to the garage pictures, the limo blood can not still be RED. But it is. The RED lie is smeared over previous dried DARK blood stains on the seat.

No dark seat stains before Dallas. Most of the blood was wiped off in Dallas.

They added RED blood to alter investigations.

It's a very good job.

Thanks by it

[marshall9509]

This was very helpful for my physio exam!

Thank you!!!

[jayathma]

Good job

[lopler123]

Awesome man!!!!!!!!!!!!!!!!!!!!!!!!

[Broken1801]

very informative. thank you!

[luizfernando240]

very good

[riecod]

Very nice and precise document. The changes of colour of the hemoglobin from blue (indicating T conformation) to red (indicating R conformation) are very instructive. The only problem in my view is the final plot. Why are you indicating 50 mmHg?. Would be better sheekshampoo to put 40 mmHg (venous O2 pressure) and 95-100 (arterial). In any case, thanks for the video!.

[funniman250x]

The 50mmHg they are referring to here is called the P50 or pressure at 50 mmHG, it is simply a baseline measurement tool when looking at a dissociation curve of this nature and does not imply that venous O2 pressure is at 50 mmHg. If you look up online the comparison of myoglobin to hemoglobin on a dissociation curve this may help to understand the concept... gotta love biochemistry!

[riecod]

Sorry funniman250xl, you have a wrong concept of P50. P50 indicates hemoglobin oxygen affinity, not a baseline, and it is the oxygen pressure at which hemoglobin is saturated 50% with oxygen. The plot indicates just the opposite. If so, the red line of the plot must be drawn from 50% to a value in X axis (mmHg). For instance, P50 value for human blood is 26 mmHg.

[Okeaola]

sheekshampoo, your vid don't say anything about CO2 in the blood.

[coconutsaregood]

@Okeaola hehe thats because its called ' oxygen transport '

[NorwegianBastard]

@Okeaola What do you mean? It says that when the partial pressure of carbondioxide in surrounding tissues is high, which means that there are loads of CO2 in the blood and the tissues surrounding the capillaries, the oxygen molecules will be released from the heme in the RBC and diffuse into the O2 deficient tissues.

It says a lot of CO2 in this video, not just doesn't mention CO2 outright, since hemoglobin is utilized as a O2 delivery system.

[lukethompson18]

Okeaola read the title

[IcyLions]

@Okeaola @Gottfried2210 Says in my text...could be wrong..7-10% are dissolved in plasma, 20-30% bonds to hemoglobin in RBC (HbCO2- Carbinohemoglobin) and 60-70% is bicarbonate ion in plasma (HbCO3-) with Cl- leaving RBC to compensate for loss.

[zackboomer]

@Okeaola The title of the video is Oxygen Transport, Einstein.

[noosha7sm]

Very good and informative thank you so much

[Gamma40k]

I thought mmHg was only used in relation to systolic and diastolic heart rates. Explain please...I've got an exam for my AS level on teusday.

[funniman250x]

mmHG is simply a measurement of pressure, it is used in may different areas of scientific study. systolic and diastolic "heart rates" does not make sense here, heart rates are not what is measured by blood pressure. In this video the mmHg refers to partial pressures of certain areas in the body. In this case oxygen tends to move from a higher pressure (mmHg) to that of a lower pressure (mmHg) .. hope that clears it up a bit

[tgdayana]

i thought deoxygenated blood is dark red nor sumthin like that.

[Andrescmil]

Me parece un video super interesanteee!:D

I guess this is an awesome video!

[iowafan180]

Deoxygenated blood isn't blue.........

Just thought you would like to know. Cut into your jugular sometime, It comes out red.....

[Chrisss2323]

That's because when the blood comes into contact with air it becomes reoxygenated.

[iowafan180]

I wasn't trying to be mean before.

Blood owes its color to hemoglobin, a metalloprotein compound containing iron in the form of heme, to which oxygen binds. There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin. Moreover, the blood inside is dark red and exhibits poor light reflection.

It doesn't change when it hits air..

[Tshannon3201]

Good information. Thanks!

[Rand0mT3chn0]

deoxygenated blood is blue in your body, but when it comes out, the deoxygenated blood has a chemical reaction to the oxygen that makes it turn red.

[Mafiadaughter]

Deoxygenated blood is actually a maroon type of colour. Its ur veins that give it the blue colour you see under ur skin.

[sheekshampoo]

Thank you for your kind comments as well.

[kylitaable]

@sheekshampoo nice

[sheekshampoo]

Please do not grab any videos i have posted. Thank you for your understanding.

[anniequiloan]

can i grab this video

[angieskidney]

I have low hemoglobin because my kidney (I only have one and it is a transplanted one) does not produce the protein that aids in making the red blood cells that carry oxygen to the muscles .. so this video I found very informative! Thank you!

[ExNihiloJimmy]

What a wonderful system, worthy of a wonderful molecule.
