Oxygen forms about 21% of the air around us. In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body.
Lesson by Enda Butler, animation by Compote Collective.
Please don't smoke. Look how much effort your body is putting into taking care of you! Why would you sabotage it by replacing the oxygen with carbon monoxide?
aperson22222 because of so called happiness
The major harm from smoking is due to the smoke particles coating the inner surface of the lungs, which not only impairs gas exchange but damages them and sometimes causes their cells to become cancerous. Compared to that regular carbon monoxide exposure is a minor problem that the body corrrects for by producing more red blood cells.
420 blaze it?
"because oxygen is overrated"
Its called Darwinian selection.
Stupid are filtered out of the gene pool.
now I have to breath manually
Kapper yup
I farted
Ikr
Same I hated eating my food and drinking my water without having to make stops for breath manually inbettween
Kapper its not manually, you dont rip your lungs out and pump them yourself, what you might try to say is conscious breathing...
Wow this truly is *breathtaking* .
johannes a ahhhhh
johannes a gtfo
I would even go as far to say it's exhalerating
*Ba dum tiss*
it takes my breath away.
Videos like this remind me of why I became a biology major. I think it's simply amazing the things our human bodies can do.
That's awesome! Can we get an update?
True. Just wanna add that pretty much all mammals’ bodies can do this. Don’t wanna make us humans sound better than others.
@@badomen7199 noo
@@syedbasiljaved6201 We are better than other animals tho
@@badomen7199 haha. Only from the human opinion. And also, not shared by many scientists (including myself).
It’s hard to claim one species being better than another, because it’s a very subjective claim.
this is gonna sound weird but learning human biology always made me cry a bit realising how amazing and complex our body is
¯\_(ツ)_/¯
Take up biology majors then and consider becoming an internist for medicine.
My incapability with math has blocked all legitimate routes for that.
yep. and yet people believe lightning stuck a puddle and made this.
Not to mention the millions of other organisms out there with their own unique systems. :D Pretty cool stuff.

Fuck you. Lmao
and you blink manually
plus you itch randomly
gg
It was a mistake reading these comments
I just love how Ted ed makes these increadible and funny videos to explain regular activities...

Me too
Same here buddy.
"It's a process you rarely think about" well now i am thanks
😆😆
Too complicated. This is why I photosynthesize. #PhotoSynthesisSquadWhereYouAt?
PowahSlap Entertainmint You're a plant?!
Ikr. Oxygen is overrated. Carbon dioxide ftw
So you are a plant. If a vegan eats you, is that cannibalism or normal vegan diet?
If it's on Wikipedia, it must be true!
+PowahSlap Entertainmint The link wasn't for citation. It was for explaining the pun in case you don't understand. Btw you think the whole process of photosynthesis isn't complicated?
it's amazing how all organs we have inside pur body seemed to coordinate with each other just to keep us alive... 😇☺️☺️

How can we not believe In God right?
@Beef Feet it’s illogical actually….
@Beef Feet it’s so funny when people say “an invisible sky wizard.” As though THAT is what I mean by God. How about ALL KNOWING, ALL POWERFUL, ETERNAL and perfect God.
Your the illogical one, if you’ve studied anatomy for 2 seconds you’d realize that it’s illogical to believe the human body itself, let alone the universe was a damn accident. get right with God sir, he does exist and we will all face him when we physically die.
We actually evolved as a colony of tissues and microbes

Literally the only thing I Remember.
+Rifat DM same
🤣🤣
and yet my mom keep saying "you dont do anything all day" i need to show her this...
lmao- ok
Watching videos like these makes me so grateful.... I love it how each and every tiny spec inside my body is working tremendously hard throughout my life just to keep me alive.... Brings tears to my eyes literally. it reminds me that I should too love my body as much as it loves me. My dear self, i am sorry if I don't appreciate that enough..i love me ya
Everytime I watch a video like that, it just reinforce in my mind the idea of an Intelligent Designer
Suddenly I am very aware of my breathing
Gabriel Lugo how many times can you blink and breathe in the same minute
Screw you, stop making me aware!
Good. Now you're aware that you breathe while you are breathing and drawing breath
Indeed!
Seculius Sam damn it. Move your damn mouth
3:59 that’s one of the things that always shocks me the most about the cardiovascular system and its length
I still don’t believe that😭 do they mean each person’s individually?
This is more useful than 10 months of school. I just watched a 5 minute video and i learned even more?
This makes me really want to quit smoking :/
Para You should, really.
Quitting smoking wouldn't only result in a benefit for your longues and your body in general, but it would change your life in a positive way (like social relationships, money)
Of course you can't stop it right away, especially of you've been smoking for months or years, but there are working ways to do it:
trying to gradually lower the amount of smoke everyday, getting a electronic cigarette...
You may consider to speak with a specialist to know what's the best for you :)
You should (U_U)
Don't be a quitter!
Michael-Francis Poliós tf dude
I second that. I really need to quit smoking for health reasons and the fact that it’s 10 bucks a pack where I’m at
This is just incredible (for non medicine students like me)... The complexity of the bodies that genes have created as their survival machines. Keep it up TED-Ed, always bringing us super interesting stuff, thanks!
I did three really important things for my lungs and oxygen delivery for disease prevention and overall wellness:
- I stopped chronically breathing through my mouth...big no-no. The mouth is NOT for breathing! The nose is on the front line of our immune system plus nitric oxide opens up airways and blood vessels
- I started using the BreatheEasy Lung Exerciser for inhalation and exhalation breathing therapy. No more asthma.
- and I sleep with a small piece of tape over my lips to keep my mouth closed during sleep...stops snoring, apnea, dry mouth and more
My chronic fatigue and asthma both are gone now and my outlook on life is exceptional because I’m sleeping better and have more energy. I’m 54.
I rarely breathe using my mouth only if i am sick!
I'm sorry but reading that you tape your mouth while asleep made me laugh 🤣
Smart
Breath: the science of lost art. All the things mentioned by you are suggested in this Book
Was so mesmerized from start to finish, the animation is amazing!
the more I learn about this stuff the more I've been taking care of things. Life is beautiful, I love Ted and everybody who contributes to it. keep up the good work your making a massive difference.
Then you should look into Islam it will allow you to appreciate what our god has done and created for us.
@@shakiramaxamed878 A Christian would tell you to look into Christianity to appreciate what his god has done. Religions have nothing but claims which can't be distinguished between themselves due to lack of evidence. How different is the Christian god from Allah, Zeus, or Vishnu? All of them are empty claims. Most people believe in them because it's what their parents taught them from childhood. Evolution, on the other hand, has biological evidence. Our embryos look the same as an animal's, we share 99% of our DNA with apes, we have the same organ placement as theirs, which means we have a common ancestor, and there is fossil evidence, too. We share the same genetic material with other plants and animals due to all living beings having the same common ancestor, our DNA with bananas is 60% the same. Dodo birds adapted and lost their ability to fly due to lack of natural predators on their island. If you deny the evidence and still believe in baseless claims, it would be the definiton of delusion.
God's is amazing...
The God you speak of made the human body incredibly inefficient. I bet I could create a better design.
Through trillions and trillions of sacrifice, the evolution made amazing living things. All while god is not known to exist.
@@AppleBS11 God is the basis of faith, not much is known but people who have a strong sense of faith believe more in god. We are all going to die either way, so I chose to believe in him just in case.
@@duevix9763 I've heard people use this reasoning but I can't understand how you can just decide to believe something haha. Bc even if you say you'll believe bc why not, it doesn't mean anything if you don't actually believe fr on the inside yknow. Oh well
Amen. As scripture says "We are fearfully and wonderfully made."
TED-ed is such an educational channel, channels like these are what produces legends!
just keep breathing, just keep breathing, just keep breathing, breathing, breathing...
Woow! Dory's dady did the same....😁
llol ikr
the animation in this video is awesome as always!
I love TED-Ed! 🙂
I love Methamphetamine
Another fabulous video, TedEd! My nursing students learning ECG loved this one.
Who else had to manually breath after watching this lmao
Fearfully and wonderfully made. 🙏🏻
You said it's complex but how can you make this video pretty much easy to understand ted ?!
Thanks for the explanation 💞
Wonderful easy explanation! I can still see it all in my head!
Wonderful easy explanation! I can still see it all in my head.
Pure art of knowledge. You guys are amazing
I'm getting little pieces of information every day, but I'm sure I'll ultimately learn how exactly my body works! I love these videos! Keep doing them, please!
Thank you for this educative video. Every breath is a miracle.
I took a deep breath at the end of the video, and it felt so good!
I really love their animations and their way of explaining! ❤🌼
Just got an A+ on my science exam because of this video, thanks
1:35 AN amazing display of digestion! Mesmerizing.
i love you ted ed you can explain a very complex topic so easy to understand
I find these videos so fascinating ❤️ love this channel❤️❤️
I really appreciated your work :)
thank you
and one more suggestion , you should make a video on insulin.. i mean how it works.
Amazingly presented. Thank you !
This makes me cry thinking about how much I never cared about my breath and my organs and my health
A small but very important part of our respiratory system has been missed out here...but I can help. Air is also supposed to pass through our nasal sinuses. Many people have sinus problems and this has an alarming knock-on effect. You see...by concentrating on this area which fails because cerebrospinal fluid doesn't reach them we don't breathe into the highest part of the bronchial tubes and this means that the highest part of our chest isn't oxygenated and besides naturally correcting this poor breathing it also seems to massage the aortic arch, especially during sleep, giving it a helping hand to pump aerated blood to the highest levels of our body. Its early days yet but it is most encouraging.
I just love how easy is to learn new concepts with Ted-Ed videos ♥
Thank you TED-Ed for these amazing videos!
Animated videos truly clear every concept 😊and make the concept interesting
I love how Ted-Ed gives you a moral lesson at the end and the credit music plays.
That was an incredible episode. It's awesome to learn more about our own bodies and with these videos I can understand how perfect the human body is
Glory be to the Creator, the One, the Mighty

thanks TED-Ed
Excellent vid tutorial. I am sure needed a lot of hard work to put it together. Thank you for sharing.
if we were breathing pure oxygen, could we hold our breath 5x longer? or breathe 1/5 as often, or 1/5 as big of a breath?
TRANSCRIPT
You breathe in about 17,000 times per day. But behind the scenes, a huge coordinated effort is playing out. The vital organs, the gut, brain, bones, lungs, blood and heart work together to sustain life by delivering oxygen to tissues throughout the body. Most of the cells need oxygen because its one of the key ingredients of aerobic respiration. That’s the process that produces a molecule called ATP, which the cells use to power their many incredible functions. But getting oxygen throughout the body is a surprisingly difficult task. Gas enters cells by diffusing in from their surroundings. And that only happens efficiently over tiny distances. So, for oxygen to reach the cell within the bodies, it needs a transportation network. This is where our 20 trillion red blood cells com in. Each one contains about 270 million oxygen-binding molecules of haemoglobin, which is what gives blood its scarlet hue. To make these cells, the body uses raw materials that become available from the food we eat. So, in some ways, you could say that oxygen’s journey through the body really begins in the gut. Here, in an amazing display of mechanical and chemical digestion, food gets broken down into its smallest elements like iron, the building block of haemoglobin. Iron is carried through the cardiovascular system to the body’s hematopoietic tissue. This tissue is the birthplace of red blood cells, and it can be found enclosed within our bone marrow cavities. The kidneys regulate our levels of red blood cells through the release of erythropoietin, a hormone which cause marrow to increase production. Our bodies churn out roughly 2.5 million red blood cells per second, a number equivalent to the entire population of Paris, so that oxygen that makes it to the lungs will have ample transportation. But before oxygen can even reach the lungs, the brain need to get involved. The brainstem initiated breathing by sending a message through your nervous system, all the way to muscles of the diaphragm and ribs. This causes them to contract, thus increasing the space inside the rib cage, which allows the lungs to expand. That expansion drops your lungs internal air pressure, making air rush in. Its tempting to think of our lungs as two big balloons, but they’re actually a lot more complicated than that. Here’s why. The red blood cells in the vessels within your lungs can only pick up oxygen molecules that are very close to them. If our lungs were shaped like balloons, air that was not in direct contact with the balloon’s inner surface couldn’t diffuse through. Luckily, our lungs architecture ensures that very little oxygen is wasted. Their interior is divided into hundreds of millions of miniatures balloon-like projections called alveoli that dramatically increase the contact area to somewhere around 100 square meters. The alveolar walls are made of extremely thin flat cells that are surrounded by capillaries. Together, the alveolar wall and capillaries make a two-cell thick membrane that brings blood and oxygen close enough for diffusion. These oxygen-enriched cells are than carried from the lungs through the cardiovascular network, a massive collection of blood vessel that reaches every cell in the body. If we laid this system out end to end in a straight line, the vessels would wrap around the Earth several times. Propelling red blood cells through this extensive network requires a pretty powerful pump, and that’s where your heart comes in. The human heart pumps an average of 100,000 times per day, and it’s the powerhouse that ultimately gets oxygen where it needs to go, completing the body’s team effort. Just think - this entire complex system is built around the delivery of tiny molecules of oxygen. If just one part malfunctioned, so would we. Breathe in. Your gut, brain, bones, lungs, blood and heart are continuing their incredible act of coordination that keeps you alive. Breathe out.
thanks i can do my assignment better
Where was this video when i needed it the most
I cried at the end. Thank you.
I liked this! An in depth explanation of a process that is usually just explained as "the lungs breathe and oxygen go in the red blood cells"
I learnt so much from this 😁
Amazingly presented. Thank you.
this is amazing, I'm a biology student and your videos are very helpful.😘😘😘
I'm laughing at the one-second clip if the guy dying at 4:39.
Lol
Wherever we feel like dying, this video will save us because obviously human body is working much better than ourselves. Infact, we should learn from it!!!!
now i am clear everything. thank for your effort.❤️
Found this video the same day I donated blood! Really puts it in perspective...
Scilic Coincidence.
How about a video showing the many flaws and unnecessary features the human body has, and how every part of our body (not just the ones we like) build an indisputable picture to our evolutionary past.
How about a video on how flawed human knowledge is and how things once thought to be useless were actually the cornerstone of our existence?
I love your animation and the way you explain things in this video
Ted ed never disappoints by their animations
Just make something positive with this wonderful body.
The blood flow at 3:54 is inaccurate.
animator had no clue how it flows
incredibly. I agree with Thrill98
eh the visuals are just to draw in more people and keep them entertained, nothing in the visuals was scientifically accurate but that doesn't matter it just helps us to understand it better.
so u mean heart has 2 eyes 😂😂 come on its
just to give some basic information
yes hearts do have 2 eyes, how dumb would it be If the heart only had one eye? then it would have no depth perception.
great animation . great explanations. Thank you.
The best video on the importance of breathing! Thank you! But of course, it's TED!
"Indeed we made man the best creation"
Who said that?
@@motazfanek2101
I read that in Quran
4:49 why he said breath out and not in 😟
Great animation, great explanations!
I love it when Anderson narrates. Somehow I feel more stupid but more calm.
If you don't believe in a Supreme Mind or Creator, this explanation of how oxygen is synthesized and used by the body should provide pretty impressive confirmation. 🙏
👌💜💜
👏3>
when you think about how you breathe without wanting to, you start making yourself breathe
wow such a beautiful explanation
to the point n simple way i love it
Such a resourceful video. I enjoyed viewing it.
🤯
Just WOW.
I feel a little weird watching this, thinking all of these things are in my lungs right now....

Thank yoy TedEd for making biology interesting. I could now learn my class 10th concepts broadly and easily
What a perfect video. Thanks!!!
shit this is making me too conscious about my breathing
But how is the oxygen extracted from air? It only contains 20% oxygen. And what happens to the other elements from the air we breath?
asking the real questions right here
Victoria S the oxygen is taken up by reacting with the hemoglobin. The rest of air is basically nitrogen and a very small amount of CO2. While a very small amount of oxygen and nitrogen are dissolved in the liquid part of the arterial blood, it's hemoglobin we have to thank for the vast majority of blood oxygen.
Victoria S its all about pressure difference and efficiency of haemoglobin to bind with element
so at high altitude we get less oxygen to our body even though there is lot of oxygen in total
Excellent video,thank you very much.
This was an amazing video, thank you so much.
You breath it in then fart it out
I hate you

Why do we breathe out CO2 as a product of us taking in oxygen?
Yehya Cheikh el Ard thanks 👌
+yehya Sorry, but in biology we learned that the CO2 is a result of your body breaking down glucose molecules, releasing CO2. Both the oxygen and the carbon come from the glucose/ food that you consumed. The oxygen you breathe in is only used in the mitochondria for aerobic respiration, which utilized the ETC to produce more ATP. The oxygen you breath in reduced into water. It never becomes carbon dioxide.
on another note, combustion does not occur in cells. if such a reaction were to happen in an organism, the cells would die due to the extreme temperatures.
Yehya Cheikh el Ard Wikipedia. Wikifuckingpedia. Are you fucking kidding me.
Please don't listen to the fool who got information from Wikipedia (Wikipedia! Are you kidding me?) and didn't bother to read it any ways. Cell respiration is NOT combustion, although it does produce minimal heat. The body breaks down food and other nutrients into molecules. One of the molecules is called glucose. Glucose has 6 Carbon, 13 Hydrogen, and 6 Oxygen. When combined with more 6 more Oxygen, the end product is 6 Carbon Dioxide, 6 water, and heat as WASTE. This heat is not regarded as combustion because the reaction is slow and does not perform the reaction.
the body breaks down glucose with cellular respiration, correct. And cellular respiration is not combustion. Such temperatures would destroy the cell, and the cell would never be able capture energy. Here is a step by step walk through for you.
1. Glycolysis, breaking down glucose through ten steps of hydrolysis and enzymes. Converts Glucose to an isomer to two 3 carbon compounds to two pyruvate molecules.
2. two pyruvate molecules are sent into the mitochondria's matrix, where the krebs cycle combines pyruvate into citric acid, then breaks it down slowly. The mitochondria can store this energy of the molecules breaking down in ATP, NADH, and FADH2.
3. NADH and FADH2 are transported to the ETC and used to create a proton gradient in the inter membrane space, which then uses the gradient to create ATP using ATP synthase.
That is a step by step process of how your cell turns Glucose into energy. Your cells do not light glucose molecules on fire to obtain energy.
This one's really good. Good job!
I am literally in love with this animation and my body 😍
Cow is the only animal which breaths in Oxygen and breaths out Oxygen.
-- Rajastan Education Minister
All mammals exhale oxygen. No animal uses up all the oxygen it inhales at a perfect scale -- so we only reduce the air by about 4ish percent.. so if you breathe in about 20ish percent oxygen, then you exhale 16ish percent oxygen.
The cow thing was stupid.
The cow thing is indeed stupid. The Hindu right wings always claim stupid things, In order to justify beef ban in his state, the minister claimed that cow is holy and that it exhaled Oxygen.
Welp, that minister might need some education :P
*breathe.... breath = "Your breath smells like booty What The Fact"... breathe = "Your booty smells so bad I can't breathe".... breaths= something is breathing.... "Cow is the only animal which BREATHES in oxygen and BREATHES out oxygen".... Grammar... It matters
Wut? Grammer? Never heard of it.
