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.
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'm so glad you found it helpful, @murarikanchan77. You are welcome. 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.
Thank you, this really helped me out a lot. I understand this 10min video way more than I understand my professor talking through a 2hr lecture in class. You are awesome!
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 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
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!
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!
I hope you know that you are truly an amazing person for making these videos for all of your viewers. It is obvious that you know your stuff, and also, that you love what you do as well. You are helping thousands of people get through Biology/Anatomy, and I am just one of the thousands wanting to express my gratitude :) Thanks SO much!
This is very similar to internal combustion engine. Valves opening and closing to let air mixture in and out, compressing it in and busting it out. Heart is our own engine/pump, only way more fine tuned and with mind of its own 💓

i’ve studied cardiopulmonary courses for 3 times with the same instructor and never got it… that’s the first time someone made it that simple. thank you🎉🎉

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
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.
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 😊
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. 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 👍🏽.
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...
You are very much welcome. Glad you found it helpful. Make sure to subscribe to the channel, because I have a lot more content like this coming to help you with biology.
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!
Thanks, @kevinhkp. I tried to make it as easy to understand as possible and I'm glad you found it helpful. That was the goal. Btw, I have another video that goes into even more detail (if you want to understand it even better. Here's the link to that one - czcams.com/video/toZI5997hz8/video.html. And if you haven't already, make sure to subscribe because I have a lot more content on the cardiovascular System coming. Have an amazing rest of your day.
Nice video, clear narration, well done. Small error noted though....vena cava are labelled incorrectly. Should be labelled superior and inferior vena cava, not posterior/anterior.
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!
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!
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.
@InteractiveBiology Definitely, I'm preparing for my "teas" exam for nursing school. Your one of my main sources for information...needless to say, I subscribed! Thanks again.
Thank you a lot , your video saved my life cuz tomorrow I have a test and I have to study about blood and other stuff , I didn't understand that part so I looked in CZcams and found you :) thanx again
i was trying to get my head around the cardiac system , i tried it many times never worked. this video just made it so easy to understand and to learn. thank you very much
This video saved me! I have. Test on this tomorrow and I didn't understand the way the book made it out. After watching this I get it a lot better!! Thank you soooo much!
@norcoboy Leslie's inspiration are actually his viewers. You are his reason why he wants to keep on doing what he's doing at his Biology website. Stay tuned. He has more videos coming very soon!
Thank you thank you thank you soooo much! you explained the circulatory system a million times better than my biology teacher, Hank Green from CrashCourse and Bill Nye the Science Guy! I cannot express how much gratitude i have for you.

OMG this is probably the 4th time having to learn this....I know it for the test and then after that its normally out of head but after this video it's actually sticking....thanks so much!!
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!!!
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 !
There was just a little misspelling noticed: the "Antrioventicular valve", instead of the "Atrioventricular valve". Other than that, this is a superb video, with a crystal clear explanation! Thank you!
I'm so glad I have found you. I'm from Brazil, and I can understand perfectly what you say, your english it's so clear and helps me a lot, as I'm studying A levels in England to be able to go to university! THANK YOU, and I will defo follow you!
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!
ya, they can be called either, or. The anterior (front) vena cava is also superior (upper, closer to the head), and the posterior vena cava (back) is also inferior (lower, closer to the feet). So, there's one that flows into the upper/front part of the right atrium, and that flows into the lower/back part of the right atrium.
Such a crisp and clean explanation, have watched many videos on circulatory system but yours is the best and from here on yours will be my go to channel for anatomy...
This is the best teaching material ever. I am really strugling to understand this thru books and my professor's lectures. This video explains it so clearly. Thanks a million for taking the time to make this video.
hi samuel, thank you so much for your kind explanation.... you gave me a relax mind by going through details of each circulation.... wish you are my teacher at my class...
This guy should be teaching everywhere. Easy to understand and good delivery
This guy thanks you 😉
way better than my past respiratory professor

Was struggling an awful lot with this topic, glad someone finally explained it in a way that’s accessible to everyone! thank you :)
thank you so much! I have been a nurse for several years and none have made more sense than yours! You are a SuperStar!

What a great teacher. Teachers are great when they make it easy for the student to learn even complicated material. Thanks!
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.
Both are correct. The superior vena is positioned anteriorly and inferior vena cava is positioned posteriorly in the chamber of right atrium.
THIS JUST SAVED MY LIFE!!!! God bless you!!! And thanks!!!!
Thank you. This is the only tutorial that made the flow of blood understandable.
Thanks a lot! It's the little things that you say that makes such a huge difference.

You lecture is elegant, a rare gift in the world of literature, especially about biology. It would be a good idea to write your own book.
Studying for A&P II practical... THIS MADE LIFE SO MUCH EASIER! Thank you for posting this :D
Thanks! Reviewing for my finals. You couldn't have explained it better!
You don't realize how much you have helped my last minute revision
Thank you very much.Im having an exam coming up but thanks to you i can understand the heart better and hopefully do better for my bio exam.❤❤

May God bless you Sam. I have a better understanding on this topic now.
Anyone from Kerala watching this for examination,Like and reply😂
Haha. Not from Kerala, but glad to have you watching 👍🏾
My exam is tomorrow and I couldn't understand a word till I saw this video :) I'm speechless thanks.. This really helped !!
You cleared up so much confusion in those 9 minutes thank you so much :)
What a great teacher
You are in just minutes
I have understand blood flow through the heart 😊
Keep up with the good works👏
This is extremely helpful, I love this video!! Finally it doesn't sound confusing and now I have a clear understanding. Thank you!

There was just a little misspelling noticed: the "Antrioventicular valve", instead of the "Atrioventricular valve". Other than that, this is a superb video, with a crystal clear explanation! Thank you!
THANK YOU I was so very confused. but this simplified the process so much.
Thank you soo much, very clear & helpful! Had it memorized immediately after watching/pausing and drawing my own heart diagram along with the arrows
This presentation was easier to understand than any of my high school biology classes. THANK YOU!
much easier to sit down and read what is all about after visual explanation. thank you very much.
Thank you this really helped me. I have an anatomy practical tomorrow.
Posterior and Anterior vena cava? I'm led to believe via cadaver experience it is superior and inferior?
just started my EKG class tonight, this helped me soooo much! Thank you!!! you are a brilliant teacher!
I would like to thank you for the excellent interactive tutorial
I'm so glad I have found you. I'm from Brazil, and I can understand perfectly what you say, your english it's so clear and helps me a lot, as I'm studying A levels in England to be able to go to university! THANK YOU, and I will defo follow you!
Thank u so much.i have less than a month before taking PCAT and I really need this to reinforce my bio knowledge. Very helpful..

Thank you so much I am studying for a Nursing admission test.Thanks
Thank you for taking the time to teach this material, it is so much easier to understand than reading a book.
