Oxygen movement from alveoli to capillaries | NCLEX-RN | Khan Academy

[@tandome]

I just have to say, your brilliance astounds me and words cant even express how much you make sense of everything, the magnitude that Im expected to understand as a 1st year nursing student. You simpify in such a way, that is unequivocal, it must be a gift. Your voice helps, its very listenable, especially your accent. Thank you, a million times over, thank you.

[@HamnaAzhar7]

amy gdala I've been trying to find words to express my gratitude towards Khan Academy but couldn't. Now you've helped me with, if not accurate, the most close words to thank Khan Academy for these amazing lectures!

Give one location in the human body where partial pressures lower than the unloading tension may be reached. Give a reason for your answer. Please help

[@Coreycry]

As a non-native english speaker, I very much appreciated your clear spelling and the recording quality, along with the god-sent subtitles! *slow clap*

[@EminentlyEms]

Fantastic video as always. The speeding up with that choice of music made me smile. Cute.

[@amaankham3137]

Emilie Ludén yeah true . sorry for replying after 4 years 😂☺

[@christinamclean93]

I LOVE KHAN ACADEMY!! _TRUE FAN!!

[@arborshell6830]

Sal, if helping others equates to happiness, then you must be one of the most blissful people on earth.

[@kavyakothalanka5242]

i never laughed while reading this topic. the music just boosted my energy!!! hahahaaaaaa!!!!!

[@GurleenKaur-e7h]

Absolutely amazing. Well explained mr.

[@carlakantyka2783]

I really can't get over how well this video basically explains lung disease.

[@MedFunds]

Great vid - but I'm pretty sure there is no thick layer of connective tissue for an O2 molecule to travel through. In fact, the membrane of the Alveoli and the Capillary are fused so as to create as little barrier as possible. Otherwise, a gas such as O2 would not be able to diffuse down concentration gradients. Correct me if I'm wrong.

[@shaewnbrown1371]

Thanks to you I'm doing good in school in scenes

[@Zajme]

Thank you so much Khan academy and mr. desai

[@karamiller4310]

This is the video I was scouring the internet for. My professor nor no KZbin video I’ve seen seems to address how pO2 in the lungs is actually computed, they just say it! Thank you thank you thank you

[@oliversparks1459]

Exceedingly Impressive Informative and Presented

[@ravenex5515]

This is far easier than other tutorials.

[@xinking2644]

just awesome, thank u bro ❤

[@shreyas7439]

the way you use the music was lit tho!

The 3D Rectangle is a great example!

[@obiwankenobi1409]

11 year old me who has to learn this kind of stuff These are confusing times

[@anneuppal4078]

Thank you so much for this...all the respiratory videos are broken down so nicely....I have forwarded it to all my A&P nursing students. Thank you!

[@luciefarar1807]

The thing you drew is rectangular prism

[@hyunjunlee2987]

great video! helped me alotttt

[@MariaTResele]

Interesting topic and good explanation.

[@SacredSalmonFish]

ok, I needed all this until 5:50 for my year 7 assignment...

[@abirhasan507]

You guys are awesome!

[@alexanderkenniethbam]

Thank you!

[@NamNguyen-he7gz]

What name of this draw app ?

[@xirishluck7]

I can't thank you enough for these videos. I wish my teachers would use them! Great resource.

[@Seekertopath]

such a awesome video

[@zungazen]

thank you

[@muhammadabubakar9712]

superb

[@ibnaliraq1000]

Very nice video thank you

[@jga4750]

you are amazing thank u!

[@AshiPongener]

You saved my day!!!

[@HabibiGa1z]

do oxygen molecules get dissolved in the fluid when travelling from the alveolis to the bloodstream?

[@ChaewonieYT]

nicely explained and its very useful. but that RBC has to be the biggest in the world

[@tsheringlhamo6233]

It's cuboid, the rectangular 3D thing

[@TheManOfRash]

i feel like im commenting this on every KAM video, but le medicine ones are by rishi, not sal

[@Paragota]

Loved it, but there is a small detail that it is not correct. The respiratory membrane OR Blood Air Barrier is actually composed of: alveolar cell, fused BASAL LAMINA (not Basement Membrane) of alveolar cells and endothelial cells, endothelial cells (of capillaries).

[@DrugoliKnight]

Paragota I was also a bit confused about this. Looking at my histology textbook shows that there really isn't any connective tissue between the alveoli and the capillaris. Instead, what is going is that epithelial cells of the alveoli make an extremely thing sheet around the inside of the alveoli, where right beneath them there's a merged basal membrane/lamina from these epithelial cells and the endothelial cells of the capillaries. This means that the distance the oxygen and carbondioxide has to move is a lot smaller then what is indicated in this video.

wow great vids thank you!

[@akshayb5265]

LEGEND!!!

[@akaursunda3082]

omg thank you so much, this was sooooooooooo helpful!!!

lol the music

[@meroOoO92]

i was shocked hahahahah

[@nourmahjoubi9771]

that made me LOL too !!

[@nabdh100]

thank you so much!!!!!

[@عبقالزهور-ب8غ]

You're the best

[@diannosaur16]

How about if the person is doing exercise? Could that not be a reason for P1 and P2 to change?

[@viviannguyen3262]

i hope i can understand all what you explain, it's related to my subjects much. Now i need to improve my english more. :(

[@elaynahallal3827]

its a rectangular prism...

[@sendygreenhoney9452]

thank you so much, i'm sure i'll have test on this tomorrow

[@iblaze1085]

You could call it surfactant

[@katean2459]

thank you for enlightening me

[@campanelli8]

exchange of oxygen and carbon dioxide at the pulmonary capillary bed . Then from that to venules vein's and at last superior and inferior vena cava to right atrium I think that's a little more simpler. Just spit balling here.

[@RICKENBOCKEN]

vena cava is in the systemic system. I believe your referring to the pulmonary circulation system. which is right ventricle to pulmonary arteries, then pulmonary capillary bed, too the pulmonary veins back to the left atruim

[@atijjain2197]

Most of you are nursing students And I'm supposed to learn this for grade 10

[@wanfaris9473]

Hello, what makes the O2 gas state to liquid? or CO2 in liquid state to gas?

[@rabiahasnain7394]

wan faris my man we the only two in 2020😂

[@artofwar420]

I like the hair haha.

[@mcsmartass8306]

its called a rectangular prism

[@aadivkole737]

Could you please specify which connective tissue acts as a medium for the transfer, love the vid but couldn't help but ask 😄😄

[@ahsanulfikri9580]

what cause the diffusion??

[@xaustinx15]

So is this true for other types of gases/vapors like vaporized or insufflated drugs?

[@lindseycoleman6800]

How can I find an easier way to get oxygen through the membrane if mine has become harder

[@shanmu1891]

Gud xplntn

[@churnel1]

so is this diffusion?

[@aparnasingh8644]

Do the lungs receive oxygenated blood

[@cassandrarinehart9970]

Aparna Singh no they receive deoxygenated blood and then carries oxygenated blood to the rest of the body

[@PeterPete]

thought you were actually going to demonstrate an oxygen molecule making its way from the alveoli to end up in the blood!!! You never stated in the description you were going to animate it.

[@Rene-uz3eb]

Given that co2 pressure in blood is in the same ballpark range as oxygen, I wonder why it is that athmospheric CO2 has any effect on us at all: it's only 0.04% of air. At levels that make you sick, say 0.2% or 2000ppm, the atmospheric CO2 would still barely effect the reverse CO2 gradient from blood to air. Ah right, it's because CO2 dissolves much more readily in water, water is a CO2 sink. Someone should put up the corresponding effective CO2 gradient. It would also seem then that alveoli surfectant condition has a bigger impact on CO2 gradient than on oxygen. In other words, CO2 will be leaving much more readily at low surface tension, and will be trapped at high surface tension. Finally, since body only has CO2 sensors, not O2, breathlessness would seem to be from insufficient CO2 clearance predominantly (the blood has a pretty large store of O2, so insufficient breathing would first show up as too much CO2 content). Speculating here.

[@lizatsoi2322]

Now im confused... So oxygen from lungs goes directly to the capillaries then to the blood then to the rest of the body? Thought that oxygen travels from the left lung-left pulmonary artery-heart-aorta-arteries-capillaries-rest of the body?

[@lizatsoi2322]

Left pulmonary vein**

[@sarahsimmons3577]

+Liza Tsoi it is implied

[@Melzare]

Jesus that went right over my head

[@lucyl1921]

Don't really get it, does that mean all that tissue is liquid? But great explanation anyway.

[@nickcolejackson6884]

Lucy L No the oxygen is moved through the tissues in the liquid phase.

[@vinnivinodh3827]

+Nickcole Jackson it is about respiration in alveoli

[@nickcolejackson6884]

VINODH SEEMAKURTI what does that mean. I am not in that class anymore. I made my A, now make yours. Thank you for late information.

[@eragon2121]

+Nickcole Jackson Oxygen turns liquid at extremely low temperaures/extremely high pressures though. The tissue isn't really entirely liquid but considering that most if its mass is accounted for by the water in the cytosol, it's mostly made up of liquid.

[@danieljluland9862]

kind of a round about way of getting to the point.

[@hamadalmhanedi6921]

WHY DID UR VOICE CHANGE !!! :(((((

[@dflesh12]

Look at the hair

[@trt300600]

Shouldnt the heart be towards the right..and since we are facing the person..isnt the drawing wrong(?) ...corect me if im wrong

[@mikelindqvist8015]

+Theo Rajan Terence no the drawing is correct as far as I can see. :)

[@sahil-um8bf]

Are u american or chinease

[@Sum_1human]

:)

[@noahhill7842]

bbbbooooooobbbbbiiiiiieeeeeeesssssss

[@lukasx543]

Not good .

[@lukasx543]

U just forgot to say the most Important , Gas molecules move from higher concentrations to lower concentrations ( diffusion) witch is a passive process and doesn´t requiere energy . Partial pressure of o2 in alveoli 100mmhg and in Arteries : 40 mmHg

[@sarabain3023]

Give one location in the human body where partial pressures lower than the unloading tension may be reached. Give a reason for your answer. Please help

[@noahhill7842]

terrible video cmon guys you can do better

[@shivonnecunningham8703]

i dont understand i am unsubscribing if you need to make it exciting

[@divyaprabha7021]

Sorry you spelled haemoglobin wrong...unless u spell it that way in whatever county you're in

[@lacm4596]

+Divya Prabha Yes Hemoglobin is the english spelling.
