The Circulatory System

[@laneybelle]

i've seen people point out the coronary artery not carotid arteries in the comments already, but the lub dub is actually the sound of the health valves closing! the lub is when the atrioventricular valves (tricuspid and bicuspid/mitral) close, and the dub is when the semilunar valves (aortic and pulmonary) close!

[@berriebarely]

What took me an hour to learn, you explained it so well in 3 minutes! Thank you!

[@dhilannagaraju3624]

actually da video is 11 minutes

[@DivineSeaDragon]

dhilan nagaraju probs means a specific topic

[@afwajbinhussein9948]

Thank you youre changing the world to a better place your influence is HUGE

[@aldabarfield7443]

Thank you for producing quality videos I can use in my middle school life science class. Your explanations are clear with simple visuals that do not distract the students from the message, the videos are well-paced, and just the right length to incorporate into classes. You make me a better teacher!

[@eagle-yt-6lock572]

what easy i am 8 years old what the heck so easy i am in uae

[@pitachipenthusiast]

Finding your videos makes me beam with joy. Anytime I am overwhelmed and confused, it brings comfort to me to find your explanations show up from my KZbin searches.

[@aytun17]

The heart revealed guys! I never thought It was that much easier! Thank you Mr.Andersen for all of your works .. you have students all around the world and you make our day..

[@roberts59a]

Hi Dr. Anderson. Just wanted to thank you for taking the time to share all of these great videos.

[@Wul-Lop]

Your videos inform & educate people around the world. Thanks from Thailand.

[@hyunpang5725]

Thank you! I struggle to gather information but this is really helpful.

[@hibaelmalik2501]

i have been struggling to understand the heart through my igcse syllabus and never understood it and thankfully it did not come but i was obliged to understand it now in my a level course and today because of this video , i for the first time in my life understand it i dont know how to thank you but you are so magical and definitely my favourite teacher on youtube , may god bless you!

[@whlllcy]

09:24 that heart beat lol 11mins here is better than 2-hour lecture

[@akshitaalikesramen5721]

whlllcy great video!

[@xatto3970]

Have my first AP bio test tomorrow, chapters 40-45! Your videos helped me so much, wish me luck!

[@thaohoangthunguyen6313]

Some people knows the knowledge well but they fail to convey it. You are both knowledgable and teachable! Your videos are very helpful for me!

[@chels.maddison]

I have a science exam coming up (I'm 14 and in a high class at school) and I find science difficult. Your videos are extremely helpful, I take notes while watching them numerous times. Thank youu :)

[@prodbyjp5986]

jesus you're fucking 20 now holy shit bruh this inspiring

[@nathankinfemichael2271]

Mr. Anderson, you'r such a great person. sometimes I don't understand what my teacher teach me, but understand your videos. that sounds cool.

[@MeBeHatz]

I've honestly learn more watching a few of these videos than when attending lessons. It's so helpful seeing all the pictures and it's so straight forward.

[@Joisushi]

you are amazing. thank you for taking time to make these videos. You have helped countless of students

[@washyomouthsmartas]

Your awesome, I can't tank you enough......! You should win teacher of the year not only once but for 10 consecutive years!

[@natura1971]

Thank you for your videos, I'm studying for my certification as a Spanish-English medical interpreter and these videos really help those of us who's main forté is in the humanities. Thanks again!

[@carigsanders1728]

Your hope is granted, Mr. Anderson. That was helpful as hell. I started watching these videos four years ago in high school and they still serve as wonderful review for my university courses. Way to do something good.

[@ReftTackarii]

I love how you go back over your videos and fix errors. I can depend on getting good information. I also love how you have a lot of information written for those who want to read up to refresh, (purkinji fibers, oh yeah!) without putting to much in verbally. You rock, thank you!

[@pixieelegance]

I love this. My almost-3-year-old was asking a lot of questions about the difference between a heart shape and the hearts in our bodies, so I finally decided to look up a video to show him. This is what I found, and between the video, a comparison to squeezing air out of his rubber ducky and then sucking water into it (obviously, he's not even three yet so I'm not worried about explaining the valves and chambers and all), and a short excursion to Photoshop to sketch some stuff out for him--after all that, he seems to at least understand that the heart in our bodies isn't the same as a heart shape, and that the heart in our bodies pumps blood through our bodies to keep us moving. And he was enthralled by the video! :)

[@akshitaalikesramen5721]

Karoline Sloma that's so cool

[@rosejames1436]

Thanks, very much, for posting your videos. They are clear and detailed, without overwhelming the viewer.

[@JamezBnd007]

Your lectures are very well prepared! Thank you on the behalf of all of us!

[@ThePolishGuitarist]

thank you for re-uploading these. Much appreciated.

[@narayangwin7892]

Thank you, Mr. Anderson! You make learning the complicated workings of the body easier to understand. Your fabulous!

[@HaiPham-rg5mh]

Mr. Anderson, how do you do the "lub dub, lub dub, lub dub" so good !!!

[@fahadhasan2353]

yeah!!

[@AbeerNasser]

I know right?!!!

[@shrees5009]

Yooo I was thinking that too

[@HaiPham-rg5mh]

Oh, it's been 4 years passed ...

[@shrees5009]

Indeed

[@GetBeachy]

I am a mom returning to college now that my kids are in college, my goal is to get my BSN, I find your videos are very easy to learn from & I thank you!!! = )

[@okayden881]

Best teacher in the universe. I have a possibility of passing my biology GCSE exam because of you, so thank you. Bozeman Science

[@beksie9234]

I'm taking an online class right now, and I can't tell you how helpful these videos are for me! My course is only text-based, so I don't ever get things explained to me like this. Your videos are saving my bacon, I'll tell you that right now.

[@daniebee92]

THANK YOU SO much! Best circulatory system explanation ever!! I been looking for years after reading and researching and never understood.God BLESS YOU MAN!!

[@dominicl456]

You and my amazing ap biology teacher are going to get me a 5 on my ap biology exam monday!!! Thank you

[@duchessheizl4210]

All I can think of after watching some of your videos, "My College and some in my Masters degree professors sucks!" It's like all my time spent in school come into waste. Wished I hadn't gone to school and watched your videos/lectures instead. LOL. Seriously, you are amazing! You make things simpler and easy to understand. Yeah, I would like to echo everyone: I wished you were my teacher! :-)

[@lalanto341]

you never fail to educate me, sir

[@moopbread5582]

My dreams are now crushed. I seriously thought blood was blue until it came into contact with oxygen until now. XD

[@jiachee8763]

Moop Bread hahahahaahhahahaha same here

[@rohitde9261]

i also thought that

[@soboredrn]

Lobsters kinda have that

[@500finsfan]

You are a million times better than my current Biology I teacher. Keep it up man really appreciate the videos

[@MissJmells]

Thank you for your love in science! Your effort and time in simplifying it with audio and visual cues is helping me way more than my text!

[@TeiloMade]

I have my A level human biology exam on Monday, and this is by far the most helpful video I've come across for revision, so thanks!

[@dinosaursgorawrish]

You've helped me so much in preparing for the SAT II for Biology. My AP teacher has barely covered organ systems at all, and my SATs are tomorrow, but your videos really help give me a broad understanding of all the systems. Thank you!

[@seleena2379]

"But it's red it's red it's red" Never laughed so hard in my life learning biology

[@AbeerNasser]

Ha ha, me too!!!

[@pallingtontheshrike6374]

I had to re-red that red-filled red statement

[@gartyqam]

Seleena i dont get the joke

[@ManasKishor]

Lawl 😂😂

[@pinruihuang8463]

well that would make you well RED haha

[@doglover1983]

YOU ARE AMAZING!!! IF ONLY MY TEACHER SAW YOUR VIDEOS JUST SO THAT HE CAN LEARN HOW TO EXPLAIN THINGS MUCH BETTER.

[@yogoo0]

This took my teacher over a week to teach the circulatory resperation and digestive system. I understand why it did for her to take that long but I am going to show this to her and highly recommend that she uses this for reviews.

[@niccinoo6993]

Who else is watching this to learn for a test

[@ElLider25413]

Me😊

[@saharalkarain3533]

Best lesson ever, i got a full mark on my exam because this video!!! BE MY TEACHER!

[@LibertangoBaila]

You make everything so clear... you're the best. Thank you for your work.

[@aymirala]

Thank you so much for doing this! May god bless your soul for helping out an AP Bio student who was getting pretty close to the end of her sad, frayed little rope (and her unit test).

[@tomastomenosYT]

YES, that's useful, like the rest of your videos. Thank you so much. I love the slight corrections that you can add to the video without interruption.

[@mierah4682]

Watching this before a test is very useful. Thank you so much!

[@davexkhan]

For my biology class, I watch your videos and they helped me a lot. Thank you

[@nawaal20003]

All your Videos really make me understand the concepts of Biology Thank You soo much for all your support and time !!

[@chloeacampbell]

You are fantastic bozeman! I'm so grateful for all the information you share - Thank you!

[@rosette_renah]

Reading ahead since am now in holiday so that I can't be lost at school. You've really helped a lot by explaining a whole sub-topic of Transport in a textbook (A Functional Approach) in just 11 minutes.Thanks

[@ChefDan1981]

Bozeman Science Great LUB DUB beat box!!!! LOL... On a Serious note. You just wrapped up a 4 hour A&PII lecture in 11:35.... THANK YOU!!!!! GREAT VID!!!!

[@evienatale]

THANK YOU for making this video!!!!! This made my spring break easier!!! #scienceproblems

[@tanyay1073]

Watching this before an exam 😂 Thanks Mr. Andersen!

[@Johnphilips1234]

Currently doing a fitness instructor course which includes the cardiovascular system and circulatory system and this video was a great way to go over what I've covered. Thanks!

[@chickenfarmer321]

This is informational and it doesn't take long with the captions and 2x speed.

[@mahatamimi8412]

You are the best , I always watch your short, very well summarized video before we start the system in class and it helps a lot thank you keep the go

[@gayathriraokonkar6778]

thank you so much . it has been a huge help to understand other systems that are connected to this one . and the extra tips were very useful too :)

[@jear4766]

You cover everything I need. Thankyou so much!

[@mellygirl23]

Great video :) I wish you could make an even longer more in depth video that also covers the structural layers and topics such as Starling's Law of the Capillary. You always present topics so clearly that I love watching your videos to supplement my course lectures :)

[@summsanihana5649]

Thank you for your videos. your videos help to explain things in a way I understand or if I want more information on certain things. plus your voice is amazing so its so much easier to listen to you. Thanks from New Zealand

[@Destructoranator]

Everything i learned in the circulatory unit covered within minutes. U are a god sir

[@yuliatsoshka2]

you are the best. Can't imagine passing my biology finals without you :)

[@elizabethmack7780]

Thanks for this video! I used this to help me study for my oral quiz on the circulatory system. :)

[@dgtsoaznpride]

My gosh watching a video is way better than reading out of a book. Makes it fun to learn

[@jellyfishpatrickstar]

Thankyou so much for making these. They help so much!!

[@Bozemanscience1]

@francesderook Nice catch. I have added an annotation in the video. Hopefully I wasn't having a heart attack when I made that mistake. :)

[@dannicamaeprecones4997]

Thank you! You have actually prepared me for our class tomorrow. Even though, I'm an Accounting student, I get to learn a lot from your videos. I just love the facts and trivias you are sharing with us. 2 thumbs up!! :)

[@samiesamie7619]

I am deeply+really proud of you We may never see But Big salute from this corner of the world

Totally would be a great teacher. This guy is awesome! A real scientist! Thanks for helping me review for my science exam!

[@TheShorticus]

Me too.

[@sanjayraju988]

Catarina Prata who doesn't

[@ItsShaday]

My biology teacher was the one who made my class know about this man, and I thank him so much because yay! test on monday and this guy makes it very easy for me to understand :)

[@hb6839]

The first 20 seconds of the video made me laugh so much, imaging what you said and what was contrary to it. Great work! Thankyou

[@summerbreezealot]

Love your video. I am trying to study anatomy and physiology myself for nursing degree. The video was vivid. But it is not the carotid artery that around the heart, it is coronary artery. U may want to correct it.

[@dennislawson7306]

First let me say awesome video. I especially liked the heart beat box. One bit of constructive criticism, the arteries that return blood back to the heart and supply the heart with oxygenated blood are the coronary arteries not corodid as mentioned in the video. One of the corodid arteries in at the top of the heart diagram you used. The left common corodid comes off of the aorta ( it's the middle of the three branches of the top of the aorta. Just thought you might consider revision.

[@rvufo]

all of your videos are so helpful!

[@sugariiesw33t]

Amazing video Mr. Paul :) You explained it so well step-by-step and it was very easy to follow and understand. Thank you so much!

[@durzafire22]

our heart does tend to beat our whole life. it's not until the last few seconds that it doesn't beat. because generally if our heart isn't beating we aren't really "alive" there was a lot of humor in this vid. i like it. it's nice to see that your classroom and your videos are not very separated in your teaching style.

[@TheToxicMegacolon]

Thank you Mr. Anderson!

[@nimmyjewtron5743]

Thank you Mr.Anderson. You helped me a lot.

Damn bro explained the whole topic better than my teacher last year, in 11 minutes, and my teacher took 3 weeks.

[@caanrdlroesa]

Interesting. Your videos definitely help me for review to get ready for my A&P final coming up.

[@spanishgamer6368]

Thank you Mr. Anderson so much. :) Without your help I would get bad grades.
