www.interactive-biology.com - In this video, I go through the process of how blood flows through the heart. It shows blood entering via the vena cave to the Right atrium, then getting pumped into the right ventricle, to the pulmonary vein to the lungs, to the left atria, left ventricle, and then via the aorta to the rest of the body.
➟ Video Chapters
00:00 Intro
00:23 Two pictures of the heart
00:48 Heart orientation
01:25 Parts of the Heart.
- Heart Atria
01:39 Heart Ventricles
01:56 Atrioventricular valves (tricuspid and mitral / bicuspid valves)
03:13 Pulmonary / right semilunar valve
03:38 Aortic / left semilunar valve
03:55 Recap - Valves of the heart
04:39 Deoxygenated blood enters the heart.
05:38 Deoxygenated blood enters the lungs via the pulmonary arteries.
06:00 Oxygenated blood re-enters the heart from the lungs.
06:37 Recap - Heart blood flow
07:40 Function of the heart
08:20 Both atria and ventricles contract simultaneously.

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

@InteractiveBiology Год назад

This guy thanks you 😉

way better than my past respiratory professor

@maryrodriguez9666 3 года назад

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.

@cheekipop 9 лет назад

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 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!

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 ❤❤

Was struggling an awful lot with this topic, glad someone finally explained it in a way that’s accessible to everyone! thank you :)

@rfcalm 3 года назад

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 Год назад

Obvious spelling error

@whooshie5172 Год назад

@@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

Finally, I understand how blood flows through the heart. You are a superb professor of biology and a brilliant instructor!

@eliztaylor2 Месяц назад

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 😊

@koruptxshun 10 лет назад

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!

@baranikoeromanga 10 лет назад

I am watching all your videos here regarding circulation system. The reason is that next wk we will start our second semester and we will cover CVS, CNS, RS and MSS. It very helpful to me to watch them prior the kick off of the semester. I'm doing my M.D program and this is my first year. Thank you very much.
