How Blood Flows Through the Heart

[@peacesearcher4598]

This guy should be teaching everywhere. Easy to understand and good delivery

[@InteractiveBiology]

This guy thanks you 😉

[@ThuPham-tj1dg]

way better than my past respiratory professor

[@maryrodriguez9666]

Thank you for almost 10 years of me using your videos! From Anatomy I and II, to Micro, through Rad Tech school, to Radiation Therapy school... I still benefit from your clear and concise teaching. It's people like you who make learning enjoyable.

[@murarikanchan77]

No doubt you are amazing tutor of biology. I had randomly clicked on your video but now i had already played many . I think I'm kind of addicted to your teaching style . You're making concepts more easier than I ever thought. Thanks ❤❤ Love and support from India ❤❤

I just went through 3 horrible videos with made up flow songs until I reached this. THANK YOU for actually being helpful! LOL

[@InteractiveBiology]

Haha. Glad to help :)

[@chandrashekarbh1948]

Well sir

[@bismilhameed2150]

i m from Pakistan and im studying Biology for 8 years but today you unveiled the HEARt

[@rfcalm]

I was one mark short of passing my test because I wrote 'antrioventicular' when labelling a diagram. Don't forget that this video has it wrong. It's 'atrioventricular'. Apart from that. Awesome video. bloody amazing! Attention to detail is important though.

[@jonellegreen4395]

Obvious spelling error

[@whooshie5172]

@@jonellegreen4395 was about to reply the same thing; I mean first of all he pronounces it correctly in the video and even if you didnt hear how he said it, you must be pretty stupid to not see the relationship between the words atrium and atrioventicular especially if the structure is right next to the other. Also I just noticed he spelled it correctly in the video's chapter name

[@sylhetgirl]

Someone give this man an award!

[@NadineKaloyios-w5d]

currently a student getting my doctorate in physical therapy!! thank you so much for making this so easy to understand!

[@vanessamoore7187]

for some reason remembering the order of functions/names in the heart has been a problem for me. like everyone else has said already you explained it very clearly and made it easy for me to remember. thank you!

[@tamaramata8415]

This videos broke down the pathway in a very easy to understand way.

[@renomnom96]

im from the UK, and omg this video has explained the system so well. THANK YOUUUUUUU!

[@nadakazzaz5561]

thank you so much. i can not begin to explain how many anatomy exams you have helped me through. i will continue to watch your videos for a long time

I'm so glad to hear that. Just trying to be helpful. Btw, here's an easy (and fun) way to remember the details of how blood flows through the heart 🤣🫀 - pulse.ly/cmmmlnkfih

[@favored57]

Thank you very much for this video. I'm studying EKG and blood flow of the heart for a Patient Care Technician class & this is very helpful. I will subscribe so that in the future when I start the nursing program this site will be my second teacher. God bless you...

[@evienatale]

THIS JUST SAVED MY LIFE!!!! God bless you!!! And thanks!!!!

[@RadhaSyam108]

What a great teacher. Teachers are great when they make it easy for the student to learn even complicated material. Thanks!

[@RaithelBR]

I think this is the best video showing how the blood flows through the heart. It helped me greatly for Anatomy, now I'm refreshing for nursing school.

[@slingsnws]

Thank you. This is the only tutorial that made the flow of blood understandable.

[@dilwilhan1116]

Your videos are so helpful! I never understand what my Anatomy and Physiology professor is talking about in class but when I am studying I watch your videos and everything makes sense. Thank you so much!!!

[@oki1985]

thanks...u made it simple yet on point!

[@InteractiveBiology]

You're welcome

[@chilliflakes08]

You don't realize how much you have helped my last minute revision

[@koruptxshun]

Thanks a lot! It's the little things that you say that makes such a huge difference. For example, "The antrioventricular is in the middle--and that makes sense because it is between the atrium and the ventricles." It's hard to see the obvious when you are so overwhelmed with everything else, so things like that really helps!

[@Darihmaster]

Perfect introductory video. Thank you.

[@InteractiveBiology]

@SHANYFREE33 Glad to hear it's helping. Stay tuned for many more :)

[@saraharnone1]

Thank you thank you thank you!! My instructor wasn't making it clear that there were different names for the same valves which was where I kept getting so confused. You Leslie are a lifesaver. I have now subscribed to your channel. Thanks again!

Finally makes sense watching this video, after 2 weeks of trying to figure it out elsewhere. Thanks and appreciated.

How many times can I say thank you on here? Not enough. I have been reading my butt off and couldn't quite understand this with the whole oxygen thing and poorly oxygenated then the veins and arteries changing colors on me but this helped me A LOT!!! Thanks! I totally understand now.

[@charlcharlie7447]

Very clear and simple to follow. Thank you. The Posterior cena cava is also known as the Inferior vena cava and the Anterior is also known as the Superior vena cava. I have just learned that too!

[@jdillla93]

I just wanna say you're amazing. You start basically from scratch. My textbook used so much jargon that it did'nt click in my head & other videos demonstrated asif we knew some knowledge. Thank you thank you thank you !

[@Wintrenight]

This was really easy to understand and I love the simplicity in your explanation. I tend to get confused when there is a lot of terminology involved. Thanks for the video!

[@RinnyRin69]

This presentation was easier to understand than any of my high school biology classes. THANK YOU!

[@valereall4697]

Thank you so very much. I am the type that doesn’t really comment but your teaching is the best.

Been reading a textbook for ages, but when I listened to this video I learned everything for my exam! Thanks soo much

[@InteractiveBiology]

Thank you! Stay tuned for more.

[@GameOver321]

I love the heart and you did a fantastic job. One thing you mentioned that almost no one else mentions is that both left and right sides of the heart are functioning simultaneously. No one mentions that. Well done!

[@InteractiveBiology]

Thank you very much, Don Johnson. I'm glad you found it helpful. It's interesting that nobody else mentions that one detail. I find it to be so cool, and also crucial in our understanding of how the heart works. Btw, if you haven't already, make sure to subscribe to the channel because I have a lot more content like this coming to help you understand how the human body works.

@Medulaman683 Yeah, we had that discussion below in the comments. Check it out :)

[@InteractiveBiology]

@Dipsy260495 Hi, unfortunately, Leslie is no longer taking requests for specific videos. He's loaded with a lot of work that it would already be impossible for him to do all requests. But, nevertheless, we hope you'll still find the site helpful. Good luck with your studies!

[@jazzyfizzlelive]

Thank you for taking the time to teach this material, it is so much easier to understand than reading a book.

[@lrw2289]

just started my EKG class tonight, this helped me soooo much! Thank you!!! you are a brilliant teacher!

[@eliztaylor2]

You are the best! You made it very easy to understand. I always had trouble understanding when the atria and ventricles contract but it was key when you stated it occurs simultaneously. It’s always explained in a way that it happens separately and that was hard to understand. With this video it all came together! Thank you 😊

[@InteractiveBiology]

You are very much welcome @@eliztaylor2. Glad you got value from it. Yes, the idea of it happening simultaneously is so important. Otherwise it doesn't work.

[@carlosmoran9419]

Awesome video! Totally clarifies the blood flow from the body, to/through the heart, to/from the lungs, back to the heart, to the rest of the body and the process repeats over and over again- thanks so very much!
