What the hell is a quart?

[leilokamaria]

Q legal

[BroXo0ki3XciZs]

Helped me write my essay ofnthe circulatory system :) thank u for the information xD

[Dre1ization]

thanks soo much, very helpful

[linktatoo]

we will be having our cardio quiz tomorrow...and this video helped a lot!

[OliviaPinguin]

This video workes better than my teacher's 1-month-explanation. Thanks :)

[xmslilithx]

@MrMitchellsLEstuff aha! You're right. I thought that was stilly too.

[xmslilithx]

Great video. I don't understand the "dislikes"

[MrMitchellsLEstuff]

@xmslilithx Perhaps the dislikes are about the "blue blood" comment. Which is silly.

[beatlesdaytripper]

this is a very useful video thank you!

[pppppp5324]

It's such a clear and useful lesson

thank you so much

[czech27]

holy S%*#!

[pinkflashnews]

yaaay thankQ :)

[thecherrycolarockers]

I have a science test in a couple weeks so like I'm studying for it now so that I get it on the test

[RAYz544]

thnx bro it helped me in my exam preparation

a thumbs up for it =D

[MegaBayleaff]

3:00 Minutes video is better than 60 Minutes Boooooooooooooooooring Lecture

[23ChitownPrince]

This video was soooooooooo helpful!!! I understand it sooooo much better im a visual learner so this video was extremely helpful

[johnpaul02ful]

wow



[MrPloppetyplop]

brilliant video! its really helped, ive learnt so much! I was just wondering whether the mitral valve was also called the bicuspid valve?

[JessicaJonasxo]

@MrPloppetyplop It is! I have a test on it tomorrow, and I asked my science teacher that today and she said it was :)!

[Theiheartmeth]

when i'm watching this on youtube, i learn more, if my teacher shows the video in school, i can't understand a thing. weird. =.=

[sonicshadow091]

lol my science teacher showed this video in school!

[ELLEHCIMG29]

thumbs up if your watching this because you have a science test tomorrow ;)

[hibamissy]

@ELLEHCIMG29

ya u r wright looooool

[MRTURTLEMAN127]

@ELLEHCIMG29 science QUIZ lol

[SayinWarriorCat]

*never blue only darker red

[SayinWarriorCat]

wait my bio teacher told me blood is neveonly a darker red.

[Adibarum]

very Intresting video...makes it all very clear

[vamsikirilenko]

Excellent wrk, Iam about to attend interview in Novartis

[andyforeverification]

thanks alot. My teacher sucks took me like 3 weeks to get this process when he explained -._.-

I got it instantly when i watched this

[Vidwhizzo]

Yea reading the comments does definitely show that a lot of people are confused about the blood. It's never blue unless you cut your arm open and dye it. Words of wisdom, don't try that.

[Vidwhizzo]

Good video. But one thing wasn't made clear, blood is never blue. It's only represented as blue to show blood with no oxygen.

[anqelblood02]

AHHAAH :)) SLMAT ..

[masmakian614]

im using this for a project on the circulatory system. I have to make a board game and have to teach 6th graders about it

[babymama20401]

@masmakian614  what

[MooNiQ6r]

Thank you very very much!

[baronnel14]

how to make this video using movie maker

[minaina12345]

whoa if there was an entire series of all these videos of physio how neat would that be!

[hockeypuckluke]

Thank you for this explanatory video. It was very simple but contains a lot of detail. By far the best video I have seen explaining the circulatory system so far

[smartinez020]

This is why I love the cardiovascular system and why I'm so fascinated!

[LikeAMacho]

The ketchup comment was unessisary

[lmoree00]

I loved the fact that this was SIMPLE. I'm a nursing student currently studying the cardiovascular system and the instructor is going hard! This video really helped me understand the blow flow. Thank you. It's simplistic and to the point.

[CaROtZzZGaM1nG]

Thankyou helped me with me homework

[nnygaston]

Great video only thing I saw missing did not mention the "Vena Cava's" by name but otherwise this is the best video I have seen with great explaination

[NoneShaltPass]

why cant my teacher show this instead of bringing in a lambs heart and get half the class to throw up

[musicismydrug1239]

THank You !!!!!!!!!!!!!!!!!



[tamtamLOVESkaty]

thank god there's someone who is NOT british explaining this subject..

[flymaster]

So thats where babies come from

[xoxomariella]

It helps me a lot. Studying nursing exam makes it easy. Seriously i havnt understand circulatory system since then till i saw this video...:-)

[maroforever]

Great video ....

[cheesy711]

very helpful. thanx very much

[taliax2010]

Thank you. This 2:58 minute video is more useful than my teacher's 2 hour lecture. (:

[LittoBUbbo]

THANK YOU. the textbook is USELESS

[Meteors0]

so helpful. thanks ;)

[markgray1109]

Its blue, why do you think people go blue when they suffocate?

[slamnxgirlxjulie]

@markgray1109 It's because the veins just beneath the surface of the epithalial layer of skin is not present. When blood is present, it give the skin the appearance of pink.

[joewmix]

I am totally confused. I have searched the deoxygenated blood color on the internet, but some says it's dark red and some says it's blue.What exactly is it? And if the color is blue, why it appears dark red when I draw the blood for a test ?it doesnt touch the air apparently

[halfbakedharry]

@joewmix de oxygenated blood is blue.

[Yarnukin]

@joewmix Its not actually blue, its just to make a point and to differentiate the two (oxygenated/oxygenated) blood from one another.

[lubnabutterfly]

@joewmix

the deoxygenated blood is dark red....not blue

[Jemdapple]

Ths really helped me a lot .. thanks for posting

[imnotagentleman12]

i have electrical wire inside me

[KaylaCakes87]

I wish it captions!

[fredzilla77]

now it makes sense XD i knew i needed a video to understand it better

[ellxoiiingrata]

this really helps.

[TheDelphineus]

Actually if you look at the veins that run under youskin you'll see that they look a little bit bluish or purplish.....Thats the deoxygenated blood going back to your heart.

[lmunno]

Good but incorrect, blood is never Blue! Blood is NEVER BLUE!!!!

[glassbladerdancer]

@lmunno IDIOT blue means deoxygenated blood red means oxygenated yeeesh....

[lmunno]

@glassbladerdancer I think you are the idiot, deoxygenated blood is represented as blue just for ease of reference. Actual deoxygenated blood is never blue, it is dark red. Pick up a book and learn for once in your pathetic little life. It's people like you that are hindering the betterment of mankind.

[emsiliepinkysandy456]

@lmunno look at ur arm look at it u can see some bluish or purplish veins...!!! yes ur right blood is not blue but the veins are!!

[lmunno]

@emsiliepinkysandy456 thanks for the reply...however the Veins are not actually blue either, when viewed through the skin it only appears blue because of light refraction. The actual veins are a whitish color.

[ZeNorwegian]

@lmunno Not neccesarily correct. The reason why the blood is said too be blue is because when the blood has gone through your body, it looses it's bright red colour and soon turns purple before turning blue-ish. The reason I can say this is because I am myself studying this, and I've got a Ambulance Teacher right behind me to confirm this.

[Ddub1083]

@ZeNorwegian yawn, youre actually wrong. The blood does not turn blue. This can easily be tested by cutting off any part of your body and holding it upside down so that the blood drains out. Under your theory if you cut off a hand, the "red" blood would drain out red while the deoxygenated "blue" blood would be blue...this isnt the case though...all the blood is red. By the way, I would trust doctors and nobel prize winners...not "ambulance teachers"...

[Ddub1083]

@ZeNorwegian and just to preempt your explanation that it only turns red after hitting the oxygen in the air...this has also been disproven...by a nobelaureate.... who did this exact experiment draining the blood into a vacuum which is necessarily devoid of oxygen...all the blood was red. Deoxygenated blood is a deeper red...but still red. the blue and red explanation is just for ease of understanding.

[ccervantes4life]

This is absolutely amazing. I am so happy and lucky to be alive.

[SanNaughty]

i need some guidance about it

[BLADExARTx5160]

So does the oxygen poor blood travel through veins and the oxygen rich blood travel through arterys?

[Carbo932]

pepeng mabaho

[Jadore780]

thank you!

[sn1pe352]

The Heart is NOT a pump :)

the old clinicians called it water-hammer not pumping

but its going to be another 100 years before we ever catch on to the profound statement I just made in academia-scholastic communities because of the backward thinking

[princessayla15]

tnks a lot for uploading this..now I'm ready to expect the unexpected from teacher...

[Magniora]

love it

[Anatronica3D]

here is nice 3d representation of circulatory system watch?v=jcKoeSPoqUM

[SlightlyPsycho96]

Thanks great video I've a science test tomorrow :)

[eegretki24]

"Blue blood" is not blue. It appears blue because of the collagen in veins that reflects a blue pigment in the light.

*When you get blood taken in a vacuum tube it is not exposed to oxygen and it is still red.

[TreeMuncher99]

No such thing as blue blood.

[jackOPSftw]

Thankyou, I used this before a science exam

[northiran]

thank you 

[MZIPOB]

this is very good. thanks for uploading. ma y i use this in my science class?

[MZIPOB]

this is very good. thanks for uploading. 

[prettyDriplet95]

this was so helpful

thank you so much for uploading!

[Darkcurse101]

very very very good video, but I need more information!!! its not enough :S

[wwechikka]

Helped a lot! Thank you!

[ScArFaCEgamingPS3]

this is bullshit, blood isn't blue before it's oxygenated! dumb fuck.

[liberatingstrife]

@ScArFaCEgamingPS3 He never said it was...science calls it 'blue blood'.

[ScArFaCEgamingPS3]

@liberatingstrife Correct science calls it deoxygenated blood.

[GreenCertains]

Thank you so much for this video, I'm studying of Health and this is the topic of first lesson!

[maymay588]

i am studing of biology, that animation is good for me !

[TheBettyVasquez]

I have so much more confidence for my exam tomorrow! Thank you.

[MyDearKyoKun]

Thank you so much for this!

[hockeyking61396]

i have a test on this tomorrow and this helped me soooo much

[MrMOSUL11]

I have a question shouldnt the blue blood contain CO2 or Not !?

[jaggysnake3]

@MrMOSUL11 Yes "blue" and "red" blood both contain CO2 but at different levels. In venous blood it's at about 45mmHg and in arterial blood the value is about 40mmHg. Alveolar pCO2 is ~40mmHg so the difference means that blood CO2 diffuses out into the lungs to be breathed out!

[MrMOSUL11]

@jaggysnake3 Thnx alot man apreciate it

[Darkcurse101]

Its weird that I didnt want the video to finish..

[myalaynaangel]

Superior and inferior Vena Cava Right atrium Tricuspid valve (Right AV Valve) Right ventricle Pulmonic valve Pulmonary artery (It is the only artery in the human body that carries oxygen-poor blood.) Lungs Pulmonary vein Left atrium Mitral valve (Bicuspid Valve) Left ventricle Aortic valve Aorta Small artery Capillaries Small veins Large Veins Right atrium

[femman01]

total 6 hours education squeezed together to 2:58 min... why didn't my teacher use this video....

[superkilla4444]

i like potatoes

[Tbatcards]

Thx so much i would have failed my science test but with this video i got a 94:)

[gully081]

42 people are fools

[misscoolcookies]

Thank you so much, really. It helped me a lot(:

[wrath1132]

BLOOD IS NOT BLUEEE! its dull red. duhhhh



[you1mirin]

@wrath1132 You Mad bro?

[aubreyhorserider]

Blood is never blue! Deoxygenated blood is in veins that are blue. The blood is not blue its self! Otherwise wouldn't we bleed blue sometimes?

[TheQazxsw17]

@aubreyhorserider blood isnt blue is correct but blood that isnt exposed it oxygen is a darker red but blood that is exposed to oxygen is a light red

[Joinproclan]

@aubreyhorserider well, as soon as it hits the air outside it would oxygenate. therefor we will never know

[aubreyhorserider]

@Joinproclan Human blood is red, It owes its colour to hemoglobin, ranging from bright red when oxygenated to dark red when not.There exists a popular misconception that deoxygenated blood is blue and that blood only becomes red when it comes into contact with oxygen. Blood is never blue, but veins appear blue because light is diffused by skin.

[AwsmRubberDucky]

@aubreyhorserider when blue blood comes out it instantly turns red cos theres oxygen in the air

[janiceelynn]

@AwsmRubberDucky Blood isn't blue, ever. It's just called that because that's what it looks like through your veins. The blue color you see is just a reflection.



[AwsmRubberDucky]

@janiceelynn :( shutdown

[janiceelynn]

@AwsmRubberDucky Haha sorry, just letting you know

[aubreyhorserider]

@AwsmRubberDucky No really look it up on any reliable website! They just refer to it as blue blood so you know the difference between oxygenated and deoxygenated! I promise i'm right on this one.

[vanessakatsoolis]

Awesome, Thank you very much for this, I have a clinical health exam in a few days, and this cleared things up for me very much.

[starringsaffron]

This video is one of the best, very clear. Thank you.

[Forgive595]

Thank you for uploading this video. Really appreciated it.

[thatstarkid]

Great vid ! Clear and concise

[Fulltonic]

does anyone have the original text? i would print it out and it would help my revision.

[MrRamandi]

Great video but one thing to mention. Blood is not BLUE. some people still use to say that blood is blue which is not true.

[shamandi246]

@MrRamandi i was saying so but maybe people still use it to differentiate the oxygenated blood from deoxygenated blood. which may it kinda of easier to understand but i get where you are coming from. btw this is a great video and so simple to understand

[nubornsol28]

Great video! Simple and to the point

[cakesA3]

This helped me so much. Thank you!

[charmGirl100]

Wow! Great video

[Johnathon394]

blood is always red. Oxygen deprived blood is dark blue while oxygen rich blood is red.

[theblackhen]

This was a really useful video. My son is learning about the circulatory system and his text on the subject was overly complicated and confusing. This video was easy to understand which will make the terms easier to remember. Thanks.

[capgurken]

i heart this

[laurensmolendijk]

You can find anything on Youtube

[Tetrademin]

@laurensmolendijk LOL thats so true ^_^

0:10 does the right side look like... nvm, thnx for the video, helped me alot

[TicTocBOMB]

OMG thx gary I have a test on the circulatory system and I do not want 2 fail and ur video had pretty good informatiom!!

[megauzbekistan]

good video

[HiroTheWonderDog]

Oxygen-poor blood isn't blue. It's darker red. The veins look blue when viewed through your skin. It's a mistake to call it blue blood.

[sashalovesmj]

@HiroTheWonderDog

it may not be blue, but lets call it blue for kids to understand

we'll correct the terminology later.

[waitwhathe]

it is really cool for science projects\

[zits666]

It's the best video in the cience world

-it's very easy "entenderlo"

[Sotardie]

Thanks for the video :) was a great help

[Purplestar997]

THANKS FOR THE HELP!!! h8 my teacher shes thick ass

thanks

[Shirkietheshark]

Thanks! This was really helpful. :)

[Rockinghorseshart]

Thanks for this animation. I've just shown it to my 12 years old daughter post her science lesson - its a very good basic explanation of the circulatory system suitable for this age group.

[Ahipara100]

I have test tomrow, so thank you very much for this video. Maybe I will pass :D

[Juriello]

What an amazing amazing video!

Thanks so much :D.
