Cardiac Cycle

[742ouq]

Thanks for the animation. I can finally explain to my family the Mitral Valve repair I had 10 years ago.

[Brawlbasher52]

My professor showed this in class without the audio; the animation itself was extremely helpful. I personally find after reading the textbook and just watching the animation again (without the audio) the whole cardiac cycle seems a little less daunting than what the textbooks crack it up to be ;)

[ojay12341234]

easy shit mayn

[apzfake]

I know the cardiac cycle by heart...get it?

[ojay12341234]

@apzfake lol

[ingrid3291]

@apzfake Haha last time I heard that I fell off my dinosaur.

[sexylilkid010]

@apzfake no. nobody geats it. dumb. lmbo

[yattrich49w]

This vid went viral on Malawi

[xLivexxLaughx]

perfect!

[ALJONES0906]

fantastic video. very helpful. makes a nice change to reading text.

[klett69]

the blood fills ventricles more because of difference of pressure between the two chambers than because of the atrial contraction action. also valves shut because of the difference in pressure. That's the way i have learnt it.

video well made, but should make those (above mentioned) notions noticeable.



[jennyramon28]

Nice!!

[RandKingification]

If ur from ACS thumbs up.

[b11k22]

why cant eveyone just use the same names for the valves?!?!? ATRIOVENTRICULAR VALVES AND SEMILUNAR VALVES. This makes it so confusing!

[x3abzkebabzx3]

If I wasn't so fed up of revising biology.. I would have taken in the information and found this helpful... so thanks!

[RobbingHoodMovies]

nice, i agree more slower

[shovad1]

ya good video but more depth would have been great: Can discuss it under:

1) atrial sytole

2) isovolumetric contraction (ventricular systole)

3) rapid ventricular ejection phase

4) slow ejection phase

5) isolvolumetric relxation (ventricular diastole)

6) rapid passive vent filling

7) slow passive vent filling

Also you can mention about a,c,v wave formation inrelation to cardiac cycle , as well as the heart sounds (s1,2,3,4)

[Tl82T]

talk slower...

[shantoramoultrie1]

learning this in school very helpful for thank you

[seanievortex]

Very good video! You forgot about the chordae tendineae too, but great job!

[osgokul]

nice video

[osgokul]

nice

[MrKarlozz]

0:07 I came

[helenheil]

Thank you so much! Awesome animation. I learned exactly what I needed to know from this. :D

[akasindm]

Great video! It helps to see it all happen together.

[TheDevildog323]

awesome!!! well done.

[vman049]

well done

[bendirkss]

hey Kathy G

[stylianos13]

wish it was a bit more detailed

[zehrameer]

easy..

[Battlemaster7]

This absolutely facilitated my heart understanding, cannot thank you enough.

[ksakingboy]

perfect

[TOMLPFANFORLIFE]

good! that helped me a lot, I haver my AS Human Biology Exam on Tuesday and this has helped me out on the Heart :)

[RockWithB]

Thanks :)

helped with my revison

[RainCloud55]

Thank you!

[addicted92]

All this time, the heart has been my most feared topic in Biology. You just made it that much less daunting.

Thank You!

[holkangel]

Love the 3D. Love the narration. Love the whole thing really. Great job! Thank you :)

[zilliberto]

Excelente!



[zilliberto]

Excelente!

[90aniruddha]

its great

[radkid06]

This was very helpful, and I have had an extremely hard time understanding these difficult concepts.

[claudemarquis1]

innaccurate depiction of ventricular filling which happens mostly (75%) during diastole, and only 25% as a result of atrial contraction

[d36u9]

told my 2nd year medschool students to watch this. thanks for posting & sharing this vid.

[Kukkumolu]

awesome......gr8 job

[Swagatam42]

gr8 job guys ... thnks .........

[Newyorksweety718]

great video!

[mosaic05]

Excellente!!! Grazi!!

[ram9236]

excellent! very helpful! Thanks.

[videowatcher50]

really good, especially the valves!

[jeanette1791]

I love it =)

[warrier12able]

thx dude

to the point and no other nonsense

5/5!!!!!!!!

[kanwaldoc88]

simply amazing!!!!!!!

[tawfiqblog]

Amazing

[princessmaram]

great vid..thanks alot :)

[kvakychka]

thanks alot

[D4vy87]

The atrial contraction does not force blood into the ventricles, it's actually passively forced into the ventricles through the atria, which is why venous pressure determines pre-load, the atrial contraction adds only a minute amount more into the ventricles and prevents the ventricular contraction which follows from ballooning the atria before the valve closes, and the atria has no valve between it and the vein, so it can't be forced into the ventricle.

[pers3as]

thank you for posting!!! helps me a lot!!!

[700Ezalb]

i wish i had that narrator's voice, so epic lol

thanks for the vid, definitely will help me out on my Systems Physiology exam

[dolceprincipessa1]

Now it all makes sense... I hope I get a good grade after watching this video.

[jvodecali]

yeah, thanks so much! this definitely cleared up my confusion about the valves!

[SubarachnoidArch]

Thank you

[ThePredster]

very helpful

[kutitoutx2]

Very helpful...thank you!

[Garko1993]

i looking for cardiac DJ and i found this :D

[ScopeVIR03]

can i ask u one thing.. is this animation is based on the real rate of cardiac cycle??

[bourbonstmc]

In reality, both ventricles contract simultaneously. They show that, but don't point it explicitly.

[coheedncambrian]

yeah, count each systole and diastole

[lbwhitfi]

Thank you; this helps ALOT!

[ITDXB]

thanks

[zunitz999]

Thank you very much this is really helpful

[GabhrooShakeen09]

thank you very much. you coulda done the proper cardiac cycle explained more in depth eg, diastole systole but 4/5

[creosotegirl]

thank you!

[ScolarshipBoy1984]

thanks 4 da video

[brandibbyx3]

omg thank you so much. this is so freaking helpful. i just spent an hour trying to figure this out with my mom with only pictures. lol..

[greensleaves7]

very helpful!! Thanks =D

[flodhi1]

Awesome video

[kristinacasco]

how can i download the video from this site to my computer? i really need it for my report.

[0siris85]

Very nice video. If you are having trouble understanding it you should watch it a few times over and over. It helped me anyways :P

[happilylil]

i am taking Levodyn and it's really the best pill i've ever tried, no side effects and all natural.

[isa2belle]

very nice video, helped me understand better how the valves work...on Friday Anatomy exam, wish me luck...thanks for the help!

[daisyluv926]

Wow, thanks to this video I finally get it!

[mrvt91]

yay i got my alvel bio exam on monday and forgot where the blood goes after it went to the left ventricle, the aorta :D

[EastMangoBoy]

Thanks!

IB Bio Exam (Paper 3) in a couple hours, lol... and I forgot how circulation in heart occurs...

Of course they want it more detailed, but this is great for a simple explanation and overview!

Thanks again!

[alhammadi666]

very informative..

thanx for posting

[willykid83]

Thank you very much for posting this.

WiLL/chicago

[azhpgirl]

perfect!

[sheekshampoo]

Thank you for your kind comments as well.

[sheekshampoo]

Please do not grab any videos i have posted. Thank you for your understanding.

[leenroo]

@sheekshampoo If you didnt want them grabbed you shouldn't have posted them on youtube!!

[Pwaves435]

thanx...will be needed for my ekg nationals next module

[karim1171]

im med student and cardiac cycle was hard to understand from notes .. this is a perfect explanation ..  it needs to be longer though to explain other things

[nerice6]

Man, isn't the heart amazing?

Very informative video! Thanks!

[Chaddo90]

This was very helpful. Can you provide something similar for the nervous system?

[airfloydmusic]

Simple and concise, very good!

[sisuacha]

Wonderful demonstration

[emilysealy]

This video is excellent for explaining the basic cardiac cycle it makes total sense now. Much better than trying to read a text book! There are other vidoes that explain the av node etc and the coronary arteries to explain this all in one go would be overload! Good to break these things down.

[aiswarya9]

Thanks this is very helpful in understanding the cardiac cycle :)

[GIRLANDLAKAIFORLIFE]

he didn't really explain about the pacemaker and the atrioventricualar node and how atrial systol and ventrical systol and finaly diastol

[DameTheLame]

can i use this video to do my biology project? i will only use it for educational purposes. i will provide a youtube link at the end and of course your username :).

[drfamt]

it will be great if illstrated the pressure changes

[monikababe]

where does the coronary artery come in this?

[monikababe]

you know the blue side does it pump the deoxynated blood to the lungs to get them full od oxygen? and does the red part pump the blood for the rest of the body?

[sheekshampoo]

You are welcome everyone.

[raymando641]

a very good video for a struggling AS biology student like myself, good job

[abondoc]

very good video i wish the narrator would have slowed down a bit. He talks way too fast.

[Ladytyden]

this was very helpful and to the point
