Thank youu

Thanks for the fact

I think you have learned from aumsum time. It was already known to me.

What more do you want, the heart pumps blood around the body

+terrance b Yes. The point is to invite you to do the actual demonstration rather than rely on video. Nothing can prepare you for seeing the real thing and knowing it's the same as what's happening in your chest. Ed Hui

sameee.

To make things worse, in an effort to simplify things, they simplified the explanation too much to where you don't get an acurate explanation, the narrator says "blood goes from one heart pump to the lungs, back to the second heart pump which sends it to the body" this kind of sounds as if he's saying that all the heart does is pump blood from one pump to another to be sent to the body, totally wrong, and confusing, I think I can make it a little more clear, please follow me if you wish: Deoxygenated blood, vena cava, left atrium, tricuspid valve, left ventricle, pulmonary semilunar valve, pulmonary artery Deoxygenated blood from the system will flow into the right atrium from the superior vena cava, then it'll pass through the right atrioventricular valve or tricuspid valve and into the right ventricle, the heart will contract and this blood will consecuently be pumped into the lungs through the pulmonary semilunar valve and the pulmonary artery to be properly oxygenated Oxygenated blood, pulmonary veins, right atrium, mitral valve, right ventricle, aortic valve, aorta Once oxygenated, the pulmonary veins will carry blood from the lungs and into the left atrium, the left atrium will pump this blood into the left ventricle through the left atrioventricular valve or mitral valve, once there the heart will contract and the left ventricle will pump the blood through the aortic valve and into the aorta and to the rest of the body This is a little more drawn out, and it's still very simplified but I think it's a little more clear than how the video describes it, I hope this helps.

Actually, I hope it helps you but it doesn't help anyone who's never seen it work before. Your second para is a list of nouns, as is your fourth.Your third and fifth paras are like tour guides. This is not informative for people who don't even understand what a pump is. The video addresses the fact that students usually don't even understand the most basic observation, which is that the heart is really two pumps- one to pump blood to the lungs, and the other to the body. The fact that oxygenation and deoxygenation occurs is also important. The names of the parts the blood passes through are actually just 'facts' to be regurgitated in an exam, at this level. They are non-explanatory. So many students have never seen a pump of any sort work nor know what a valve is, so calling something a mitral valve is non-explanatory. In any case, the video has one overriding point- it is about the discovery that we made that you can actually demonstrate this wonderful thing working in a school lab. Not a model, not an animation, but the real thing- and students can use their own hands to make it work. If you do this, you will understand and internalise the heart's function directly by experience- this is something that nobody knew could be done in hundreds of years of study of medicine and anatomy. Please try it.

Because you dont understand xD

Ian Ciborowski I didn't understand what u said now more than the video

The title should be changed to "How to bitch & whine about how not to teach about the heart, then make the same mistakes in teaching about the heart." Yeah, it's a long title, but it covers all the basics.

Ian Ciborowski I agree with you

Yes

They also use brains as stress balls

no

no, I actually want to get a fresh heart now... just to get an all natural water gun!

Noesn't

Eric P. Tran Excuse me i have brown hair. I'm not black or blonde, i know i'm not smart and is not my fault. I been trying so hard. So give me a break!!!! Oh and people who have black or blonde hair are smart. So don't think that blonde hair people or black hair people are not smart!. Anyone who have different hair colors or skin are smart in anyway! But for me i'm not smart at all but i try. so that what matters to me the most.That i try so hard that i'm starting to improve more by little bit each day.

LilacSongz there are SOOOO many different types of doctors. The heart is a nice place to start if you're trying to learn to be a doctor. Keep searching around in these videos. Watch some videos on the immune system, I found those quite interesting. How to get your grades up? Well, this might not work for you but it worked for me. Take the topic you hate or struggle the most in. Think about this topic in a really harsh way. Find its flaws. Now whenever you learn about this topic, think about its flaws and work around them or try and patch them. It might seem like complete nonsense, but i told you it worked for me.

Rcm E Thanks!

No its not

Aj1994 GT I thought it was. It was more like "The heart is not as confusing as you think" It was also weird. I never thought the heart was particularly confusing, but he was talking as if it was this super complicated subject that few people understand. At some points it was even a bit condescending. Weird.

I'm not trying to show it's super confusing. I'm pointing out that nobody ever figured out that you can ACTUALLY make it pump outside the body. That's why the 'actually' is in the title. It's really easy to understand what the heart does once you know about circulation, but Leonardo didn't. So he really was 'super confused'. Nowadays, people aren't confused, but they still don't actually see it working. I mean, you can see your arm working, and you can feel your biceps contracting and your forearm moving. But until I discovered this demonstration (removing the atria), educators and students had no opportunity to actually see the heart working. That's why there are so many animations on KZfaq, and why so many science lessons get students to make models of the heart. It's actually a new discovery that we are announcing here- a new way of demonstrating heart function in schools. Regards Ed Hui

Edmond Hui That's pretty cool actually. But looking through the comments I can see that I am not the only one with this opinion. The title is not good. The fact that you need to explain to me what you did shows that the title, and video, did NOT deliver that message at all, which means the video delivery is not good either. Don't get me wrong, it was a good video, as all these ted-ed videos are, but the message isn't clear. At no time did I think this was a new discovery and I didn't grasp that it was important. I had no idea that no one figured out you can't make it pump outside the body (which to me, is remarkable after all these years!). None of this was mentioned at all, so to me it just seemed like an overly long way of saying "look how simple the heart is!" That is why it was weird when you started going through the whole procedure.

You're right. It was exceptionally difficult to come up with a title and a script, and within TED-Ed's guidelines (how it fit with the other TED-Ed lessons) and the time limits. You'll also be amused to know that when I show this to doctors and surgeons, they are either in agreement that it's cool and wonderful that the thousands of anatomists and students who have looked at the heart also failed to discover that it would work when manually pumped; or they fail to see the significance at all- 'yes, but we already know how it works!' I was lucky that the peer reviewer at the journal where it was published was an experienced teacher, and her comment was that she couldn't understand how she could have taught the heart for decades and failed to find this technique herself! Personally my slant on this is that it proves that genuine scientific discovery (be it ever so marginally useful) is available to everyone. I will forever be amused that I found something that Leonardo could have but failed to find. He would have been greatly amused to see it pumping. I'm told by the keeper of the Queen's pictures that he is certain that if Leonardo knew of this technique, he would have recorded it.

The narrator is a software developer. He's just following a weak script (no pun). Typical in our day in age to get a lazy explanation in lieu of an expert. Mind you, the goal seemed to be to give an understanding of a complex question to lay people, inside 5 mins.

There is a context to everything. This is not standard practice turned into animation. It's a NEW technique. How often do you come across something that Leonardo studied, could have found, but missed? The figure 8 animation is not the important point. It's an illustration of the misconceptions that can occur when you learn about the heart from an anatomical label perspective, rather than a functional point of view. This technique is designed to introduce the heart from a directly practical, functional point of view. The important point is the invitation to get a real heart and look for yourself, to get a direct, tactile and visual understanding of it as a pump.

teddnet Very often, what is intended may not be what interests the viewers. Any way. who did the animation? Edmund Hui or Tednet? What is Edmund Hui's role in this lecture? Narration or idea?

KK Fung Edmond Hui most likely wrote the lesson (idea). Addison Anderson did the narration. Anton Bogaty did the animation. 4:13

HY DX Correct. I discovered the technique while mentoring Archie Taplin for his TEDx talk and wrote the scientific paper describing it. See the TED-Ed lesson Dig Deeper section. I wrote the script and had the opportunity to advise Anton Bogaty as he developed the animation. The animation serves a dual purpose of announcing the technique in context to a wide audience of educators around the world, as well as giving sufficient detail so that anyone can see it for themselves. It is not designed to be a substitute for the demonstration. It IS supposed to be fun. :)

KK Fung haha lol I’m in year 8 an I understood it better than u on the first time

+kristin martin You're welcome. But try and do the actual demonstration yourself. Ed Hui

Yepp!!!

of course

Your a wyrm

Oh but "it's so cuute!"

Had exactly the same reaction... All the given facts in the begging, about how everybody have no idea how a heart works, are completely misleading. MRI anybody? truly disappointed :/

***** Sorry you're disappointed but that's not the aim of the animation. It's an invitation for you to try the demonstration for yourself. If you want to see the full explanation of this new method of teaching the heart, please see the 'Dig Deeper' section of the TED-Ed page for this animation. Ed

ive got homework on how the heart works i thinkit helps!!

Yes I did. And this video is also crude. But the message is that students can actually see the real thing for themselves. Ed

a heart can be restarted in certain situations though

@@tanish8644 yeah, that happened to me

Your heart stops approximately 2/3 of the time during diastole.

what makes you think that :?

​@@Endokuu they put the pig's heart but they did put their heart too

When you see the demonstration done live, especially with a pig heart which is pretty much exactly the same as your own- the effect is very moving.

Me too!

Alejandro Mendez same

Hi Natalie. Please understand that the point of the video is to invite you to do the demonstration yourself. If you are a medical student, I'll bet that this demonstration was not shown to you during your studies, because as far as I know, it was not known that it was actually possible. If you follow the simple instruction of removing the atria, you can work the ventricles and see the valves opening and closing directly, and not through some animation online. The video itself is not meant to show how the heart works- the animation is meant to be simplistic. But when you actually see it live, it's amazing. Hope you give it a go. Regards Ed Hui

Because there was no time. It's mentioned by several commenters below as well.

you're quite right; hard to believe no one looked this up a bit before writing the video.

Al- Nafis possibly. Galen definitely not. Da Vinci definitely confused. If you read what Da Vinci wrote around his wonderful heart drawings, he thought there was nowhere for the blood to go, so he was convinced there were holes in the septum between the ventricles, and / or back flow through the valves. If he had actually tried this technique he would never have thought that. Martin Clayton, keeper of the drawings in the Royal Collection, confirms that Da Vinci actually gave up anatomy after failing to figure out how it worked.

@@SubscribersWithaFewVideos mnje

muscle contractions in the heart, make the chambers "grow smaller", creating pressure that pushes blood to the ventricles/ out through the arteries.

A patch of muscle called SAnode initiates the process of contraction of the heart chambers.

..... it's the same thing. Just different names

Explain how it works then? It's a fairly complex type of pump

if you push really hard on your temples you can

Yeah I didn't learn anything either

Cuz you guys already know all this. But someone doesn’t. Not me.LOLZ

LOL...

That feels quite disturbing.

Browny same

Same here :/

Krhodes02 meeee

Come on, man...i understood everything this video said. The cartoons are silly, but can't we have some fun with things once in a while? Why does everything has to be so serious?

***** I can agree with you about the reading through a book all day to learn. However, I find for me personally the best way to learn is through a good professor and the use of his/her drawings complimented by his/her explanation. But I will say that from my experience, everybody seems to learn better or worse in different ways. I think I was just a bit irritated that they really dumbed the lesson down as far as to completely remove the left and right atria, not explain the difference between arteries and veins, etc. As far as the cartoons, that is just my opinion. If I were to be actually learning about the heart for the first time it would be hard for me to grasp because I just feel the cartoon look is kind of insulting and childish. Like I said that is only my opinion and I realize some people may like the cartoons and actually feel more at ease with it.

AnAngryBlack This is a 5 minutes-video for general public, you can't just hope to communicate many things, that's why they use animation, it's easier for the general public to make a very general idea about the topic.

***** I can respect and agree with that. I see your points and it does appear that the whole cartoon thing really does either help people or kind of set them back depending on the person's views. I agree that animations in general really do help a bunch after getting a general explanation. Good luck in your art school!
