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?

now I have to breath manually

Wow this truly is *breathtaking* .

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.

this is gonna sound weird but learning human biology always made me cry a bit realising how amazing and complex our body is

MANUAL BREATHING ACTIVATED!

I just love how Ted ed makes these increadible and funny videos to explain regular activities...

"It's a process you rarely think about" well now i am thanks

Too complicated. This is why I photosynthesize. #PhotoSynthesisSquadWhereYouAt?

and yet my mom keep saying "you dont do anything all day" i need to show her this...

it's amazing how all organs we have inside pur body seemed to coordinate with each other just to keep us alive... 😇☺️☺️

Mitochondria is the Powerhouse of the Cell.

Suddenly I am very aware of my breathing

Everytime I watch a video like that, it just reinforce in my mind the idea of an Intelligent Designer

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

This is more useful than 10 months of school. I just watched a 5 minute video and i learned even more?

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!

Who else had to manually breath after watching this lmao

This makes me really want to quit smoking :/

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.

3:59 that’s one of the things that always shocks me the most about the cardiovascular system and its length

TED-ed is such an educational channel, channels like these are what produces legends!

Pure art of knowledge. You guys are amazing

I really love their animations and their way of explaining! ❤🌼

the animation in this video is awesome as always! I love TED-Ed! 🙂

Where was this video when i needed it the most

now i am clear everything. thank for your effort.❤️

Fearfully and wonderfully made. 🙏🏻

I find these videos so fascinating ❤️ love this channel❤️❤️

Another fabulous video, TedEd! My nursing students learning ECG loved this one.

i love you ted ed you can explain a very complex topic so easy to understand

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 just love how easy is to learn new concepts with Ted-Ed videos ♥

Thank you TED-Ed for these amazing videos!

Thank you for this educative video. Every breath is a miracle.

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!

just keep breathing, just keep breathing, just keep breathing, breathing, breathing...

I took a deep breath at the end of the video, and it felt so good!

Amazingly presented. Thank you !

Just got an A+ on my science exam because of this video, thanks

I really appreciated your work :) thank you and one more suggestion , you should make a video on insulin.. i mean how it works.

Excellent vid tutorial. I am sure needed a lot of hard work to put it together. Thank you for sharing.

Animated videos truly clear every concept 😊and make the concept interesting

You said it's complex but how can you make this video pretty much easy to understand ted ?! Thanks for the explanation 💞

God's is amazing...

amazing ,, now I appreciate my body and my life thanks TED-Ed

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 learnt so much from this 😁

Wonderful easy explanation! I can still see it all in my head!

Wonderful easy explanation! I can still see it all in my head.

I love how Ted-Ed gives you a moral lesson at the end and the credit music plays.

this is amazing, I'm a biology student and your videos are very helpful.😘😘😘

Love u TED ED...FOR THIS TYPES OF VIDEOS

The best video on the importance of breathing! Thank you! But of course, it's TED!

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

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"

Amazingly presented. Thank you.

1:35 AN amazing display of digestion! Mesmerizing.

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?

Found this video the same day I donated blood! Really puts it in perspective...

I love your animation and the way you explain things in this video

I am literally in love with this animation and my body 😍

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.

Just make something positive with this wonderful body.

wow such a beautiful explanation to the point n simple way i love it

Thank yoy TedEd for making biology interesting. I could now learn my class 10th concepts broadly and easily

o corpo humano é um incrível máquina de órgão á tecidos á celulas á proteínas à minúsculas Particulas Somos Uma máquina quase perfeita

I'm laughing at the one-second clip if the guy dying at 4:39.

I cried at the end. Thank you.

great animation . great explanations. Thank you.

I feel a little weird watching this, thinking all of these things are in my lungs right now....

when you think about how you breathe without wanting to, you start making yourself breathe

Such a resourceful video. I enjoyed viewing it.

This was an amazing video, thank you so much.

"Indeed we made man the best creation"

🤯 Just WOW.

Excellent video,thank you very much.

wow this truly is breath taking.

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.

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. 🙏

Ted ed never disappoints by their animations

What a perfect video. Thanks!!!

In America, you breathe oxygen In Russian OXYGEN BRETHES YOU!

Me when i hear about breathing: Autopilot disabled

the animation is just chefs kiss

Very informative video and very well put together.

Cow is the only animal which breaths in Oxygen and breaths out Oxygen. -- Rajastan Education Minister

shit this is making me too conscious about my breathing

Thank you Ted share. Cảm ơn Ted đã chia sẻ.

Great animation, great explanations!

"hey that cell looks like an eye oh my fucking god"

So just curious, who fast does this happen? Does it all happen in one breath and then all the excess is breaker out, or how long does it take for the absorbed oxygen to get to my (for example) fingers?

I enjoy learning more about personal wellness I love it!

awesome video....hats off to the graphics....completely understood

The blood flow at 3:54 is inaccurate.

You breath it in then fart it out

I enjoyed this video. Great animation. Super👏👏👏

Wow this truly, is breathtaking.

Can U Please Explain Why Farting Is Harder Than Breathing ? 😂
