How Blood Flows Through the Heart

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.

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

This guy thanks you 😉

way better than my past respiratory professor

[@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 ❤❤

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.

[@mariedoubledee]

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!

[@MariaSanchez-uo6nh]

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

[@cheekipop]

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!

@issayk1 Hi! Thank you for watching. Yes, we had the discussion on the error below in the earlier comments posted. You can go ahead and check them out. Please stay tuned for more Biology videos :)

[@sylverteaz]

I have an anatomy test on Monday and this helped me - it was easy to follow and a clear demonstration! Thanks for posting.

[@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

[@InteractiveBiology]

Thank you soo much, very clear & helpful! Had it memorized immediately after watching/pausing and drawing my own heart diagram along with the arrows

[@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!

[@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!

[@TANtrum30]

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.

[@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 😊
