How the heart works

[MrDaldagnuur]

i have a question. Where get heart singal from? and how? is brain controlling heart rate or blood flow?

[thinsteel99]

@TheGoldleaf99 than why are u watching this?

[TotalNightmare7x]

far more understandable than teacher

[gresiana318]

thank you this was very usefull

[dansnake27]

i have to learn and memorize this in 7th grade :/

[Smann54]

my teacher failed to explain this without everyone being confused. my book only made matters worse by introducing advanced terms which I didn't need in a basic biology class.

Thank God for YouTube & Internet Videos.

[ether150]

fuck a textbook,just youtube what you need to know.

[twilighter3456]

Awesome, thanks for the video!! I just realized that I can learn more stuff from video than my hard packets i receive by my teacher!! :D

[fllagunos]

Great Job



[xSweetThing]

handig als je tto doet

[mysparklingRuby]

@xSweetThing hahaha ik doe ook tto, ik doe nu een project over het hart

[Anna32071]

Aweeeeeeeeeeeeeeeeeeeeeesome..­..

[PrizeClickHere]

4 people don't have hearts

[st3v1p00]

BRILLIANT THANKYOU!

[TheTamia298]

this animation is gr8 i learnt what my teacher was trying to explain in 1 hr in 3 mins

[Rathanasan]

Thanks!

[CJ201006]

My A & P instructor recommended this video ... TWO THUMBS WAY UP!!!

[AFFirefighterEMT]

Fantastic!

[Andybreathe]

Thank you so much. Thumbs High Up !

[lolguy40]

CHOPEEEE RICOOOOOOOOO!!!!!

[medicalanimations9]

This is really amazing animation, keep upload. Thankyou

[Urfriendphoenix]

WOW the human body so amazing I love learning about the human body.

[MrASHATACK]

fantastic

[bharatpant785]

fantatic animation certainly thanks... learnt a lot from it

[lorena2267]

Great educational animation of the heart and easy to understand. My biology book is a hard read and hard to understand. Great job in simplifying.

[ccraven11]

great video. its hard to learn it just on paper. nice to see a working example =]

[phantomkid7411]

Isnt there a tricuspid valve? Or was that the pulmanary valve. Great video btw

[ccraven11]

@phantomkid7411 it does say tricuspid valve. it is also called the aortic valve. this pumps to the aorta.

the pulmonary valve (or bicuspid valve) is in the rght ventricle which pumps deoxygenated blood to the lungs

[robbysbaby517]

this completely saved me from failing..

[120615prasa]

great thnx

[hock105]

thanks

[gcoverkill]

I don't get how 3 people dislike the human heart.

[splashie777]

@gcoverkill

They are called trolls (Internet term for people who dislike anything on the internet for the sake of being complete losers as far as im concerned)

[sweethorizons123]

this video is quite good

[tyecofield]

show a hickmanline and pacemaker

[ema1171224]

SA node is like a light that is turned on> SA node fires & the atria contract> AV node fires & the ventricles contract. The heart is a pump which pumps blood all around the body. The heart has 4 chambers. There are 2 upper & 2 lower. It has an electrical system which works to stimulate contraction of its chambers. The EKG reflects normal or abnormal function of the electrical system.

P=Atrial Contraction QRS=Ventricular contraction T=Resting time before contraction

[splitecho]

WHY CAN'T MY BOOK TALK TO ME IN A SEXY ENGLISH ACCENT?

[KrysandJulianne]

Thanks for posting this! I'm also in an Anatomy and Physiology class and reading about it doesn't effectively explain all the directions and motions. This helped immensely. THANKS!!

[l3aIIin23]

thanks, my book is a piece of shit

[JuJuHouse24]

youtube can be so awesome for revision

[MrMrGadgetboy1]

the nipples where just too much...

[iPodLocK3R]

@MrMrGadgetboy1 not for science YA CHUMP!

[ForteIIV]

Perfect!

[shane364]

It is extremely informative, How elaborative explanation!

[pinch14]

well Done!

[bozez1]

Don't worry, It's not what it looks like, a highly engineered mechanical pump. It's just a series of accident, after accident, after accident, that very conveniently put all the parts in the right place including valves to fight the effects of gravity which would otherwise cause the blood to pool in the bottom of the ventricals, and fully equipped with an electrical power unit that forces the contraction. It's all evolution honey...don't worry...go back to bed now...kay?

[deriik2020]

@bozez1 huh? Are you failing miserably to describe evolution and natural selection? (facepalm) Nat selection: Trait best suited to survival will help an organism survive over similar organisms and pass on its gene/trait. Over millions upon millions upon millions of years what was once one valve pumping blood becomes 4. Oh my 4 valves in a few hundred million years...surely that wasn't a long enough time for new traits to show up in the gene pool and get passed on!

[bozez1]

@deriik2020 Derilict, are you failing cosmically to provide any mechanism or pathway to your supposed process, the odds of which are galactically prohibitive. Yes! Could it be your complete lack of understanding the realities of biology or is it that you are obscenely brainwashed? Probably both. Over millions of millions of billions of years, would you expect a mechanical pump to self assemble with electrical conduction system in tow. What came first SA Node or Valves or ventricles?

[deriik2020]

@bozez1 Maybe it's because this is youtube and you can't type much? Way to be atroll too.

[deriik2020]

@bozez1 I mean if tyou wanna join the big boy table and have a grown up discussion that's fine but if you want to challenge people openly and insult them. As I said millions upon millions of year for traits to develop. You can';t prove it isn't evolution but there are plenty of complex systems around like the flagella that do support what I'm saying. Feel free to look into it whenever you want. The onus is on you to be an adult and self educate yourself if you wanna have a debate.

[deriik2020]

@bozez1 But it's fairly obvious that isn't why you're here.

[drift1356]

Science form 3..

[72caliman]

Simple enough.

[fudgecake001]

you should seriously write our school textbook (Y)

[Wii624]

The circulatory system makes me cringe

[tatylacalenita]

This was so helpful... better than reading an anatomy book!

[rejythecat]

0:12 couldnt they have used a naked girl

[enriqueification]

@rejythecat Pervert

[zagros24]

How Sinoatrial Nod produces electrical impulses? I didn't know we have a power plan in the heart. 

[NismoCA]

@zagros24

It has special cells that allow them to create electrical impulses upon contraction.

[hms6114]

Vein carries dirty blood tot he heart and artery carries or supplies the heart with clean and high rich oxygen blood away from the heart to the body

[glitch417]

It all makes sense now.. Ty..

[moustikabouz]

i am afraid now from what i have inside me, and i am so worried if some mistake happened to any part of my heart :S.... helpppp meeeeeeeee

[LiteracyLabyrinth]

Better than reading that confounded Anatomy and Physiology monster!

[splashie777]

@LiteracyLabyrinth Ahmen!

[jetaimerinrin246]

Oh jeez im only in 5th grade n im learnin dis stuff

[enriqueification]

@jetaimerinrin246 Yes you are only in 5th grade and you need to be better on grammar.

[jetaimerinrin246]

@enriqueification well i was using my ipod on dis thing......... TYPO!!!

[jetaimerinrin246]

Haha im dun with my science hw i jus needed to noe how it works if i didnt my science teacher is gnna get mad at me ick in front of da whol class yeshhh

[SandraV10]

omg ! thank you so much i learned alot..i have an exam tommorow and this is just everything i need to know =)

[sonicxlc123]

the only thing i can under stand is a heart from a car engine that runs! an works!

[Laralook109]

thankz a ton...for da vedio...it was allot of help....SERIOOUSLY!!

[adventxero]

best vid evar! I have to find more like these

[Serpico261]

@adventxero try this one...its in german but the shortcuts are similiar..

Left/ Right atrium/ ventricel (LA, RA LV, LA) also the hearttones M1 A1,2 etc

[Medfield246]

Both the pulmonary arteries and umbilical artery carry deoxygenated blood but usually when they say artery it means that blood move AWAY from the heart whereas vein blood move TO the heart or in the direction of the heart (hepatic portal vein). :)

[MotorolaGx]

This.....is freakin' amazing. I have a exam tomorrow and this covered a major portion of what i needed to learn... and only in 3 minutes!

[somaliangle]

@MotorolaGx how does it help looks boring to me

[chrissline77]

better than reading an anatomy book!

[chrissline77]

@MotorolaGx ..did you pass?

[Rexmanghay]

heart god gave me

[joeynap860]

@Rexmanghay shut up

[lostchee]

tnx

[ckskenneth92]

no no. U're wrong. Umbilical artery also carries deoxygenated blood

[khalid95151]

yup dats true

[camry1971]

Pulmonary artery is the only artery that caries deoxygenated blood !
