How do lungs work? - Emma Bryce

Take a journey into the lungs to see how the respiratory system and automatic nervous system work together to keep us alive and breathing.
--
When you breathe, you transport oxygen to the body’s cells to keep them working, while also clearing your system of the carbon dioxide that this work generates. How do we accomplish this crucial and complex task without even thinking about it? Emma Bryce takes us into the lungs to investigate how they help keep us alive.

Your comment made me breathe manually

He forgot to manually breathe. Maybe that’s why he hasn’t replied for 4 years.

You breathe automatically until you think about it!

[@Th3Misterio]

Because becoming conscious of anything brings freedom. So, now, that you're conscious of breathing, you are free to choose how to use it.

[@Kakashikewl]

I had a strange panic attack when he said that we never forget to breath... Almost died. 10/10, thanks Ted :(

I did three really important lung-related things for my disease prevention and overall wellness: - I stopped chronically breathing through my mouth...big no-no - I started using the BreatheEasy Lung Exerciser for inhalation and exhalation breathing therapy - 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 and take no meds. Health is wealth!

I love the Ted Ed videos I am currently studying bioscience and find the videos the unit coordinator recommends very long which makes it complicated for me in the long run. I find these quick and simple it covers everything which makes more sense.

[@musicallife7906]

Respect for his confidence way while he teaches us......

[@kevinmoore2501]

This is a great video, and way to learn. However, when you talk about the breathing muscles, I couldn't help but notice that there wasn't anything said about the sternocleidomastoid which lifts the sternum to increase volume in the thoracic cavity. At least, that's what I learned.

[@jmitterii2]

We all went into manual breathing watching that part. LOL!

[@RoScFan]

Funny thing is the video didn't affect me, but the comments, like this one, did. Alas, it's easy to kick it back into automatic mode. Just try to forget it, try to relax the chest muscles; don't try to force them to stay put, try to not do anything, just let go. It still breathes.

[@shaunjulianazzopardi6463]

This video is very good. I real good understood thanks

[@Timvandervliet]

Thanks Emma

[@anthonyg1111]

the way the diaphragm is illustrated is wrong

[@WsciekleMleko]

Yup. Diffusion works by making entire system equal. It doesnt transport entire oxygen on opposite side and co on opposite side. What it does is that if you take any small volume at any side of mebrane, there has to be equal amount of o2 and co2. Then it becomes equeal. But since you used some of oxygen in metabolism, there will be lower concentration in blood than in the outside air.

[@sooooooooDark]

2:19 isnt that visualisation kinda wrong? shouldnt both sides have equal amounts of o2 and co2 after the diffusion happened? its shown as if all the o2 goes into the blood and all the co2 goes to the lungs - but technically shouldnt it be so that in the end both sides have relatively equal amounts of both?

[@Markus9705]

You're correct. Moreover, diffusion is not the only process here. The process which transports the gases over the membrane is called *osmosis*.

[@emeraldstars345]

TheLeftLibertarianAtheist I think that you may be mistaken. Osmosis specifically focuses on solvents moving through a semipermeable membrane, not gases. Though I do agree that the visual representation is wrong :)

[@Markus9705]

emeraldstars345 Osmosis works for gases too.

[@VinSad]

TheLeftLibertarianAtheist Osmosis is only for water and other solvents. In this case, the solvents are the other gases in air.

[@ptgriffin]

Agree with Vin Sad and emeraldstars345 . Check out the link if you disagree.. en.wikipedia.org/wiki/Osmosis
