Attention: The mitral valve is the same as the bicuspid valve. Also a good way of remembering which valve comes first is "Tri it before you bi it". Hope this helps.

Great video! Thank you for making the flow through the heart much easier to understand!

Finally, a video that explains this process in a way I actually understand. Thank you!:) It really helped that you drew the lungs…it helped me understand the big picture.

This is far and away a better explanation than my instructor's lecture. I am definitely coming back to these videos as a re-cap before all of my A&P exams. I hope there are some videos for patho-phys and biostats too!

absolutely fantastic, very well broken down and very well explained! I'm currently doing a degree at university in Sport and Exercise Science and it was fantastic for basic anatomy revision! I shall indeed be sending this to my peers!

I have an A&P test tomorrow morning and this helped me SOOOOO much! At first i thought the heart was all one big circulations like all the chambers just flowed into eachother and then out the aorta but it took me forever to see that the lungs were actually the middle man between the left and right chambers.

THANK YOU SO MUCH! You taught me what my teacher failed to! BE MY TEACHER!

I love this teacher, one of my favourite on KhanAcademy! Thank you for the super clear videos and drawings

This is by far the best explination of the blood flow in the heart. Had an "oh i got it" moment. Thanks a lot

I remember learning this in a biology class when I was in sixth grade. Now 25 years later I kind of forgot the process. Best explanation ever sir and thank you so much for making it so easy to understand. Your drawing was spot on too

Great video, sir. It really helps me. Thanks for your great work, i really appreciate it.

Your explanation was way better then my anatomy and physiology teacher, thank you

This is such a great explanation & super easy to understand! Thank you!

You mentioned the Pulmonary Artery carrying deoxygenated blood to the lungs, and oxygenated blood being returned to the heart/ dumped into the Left Atrium, but you never mentioned O2 rich blood being returned to the Left Atrium by the Pulmonary Vein.

I'm sure you were explaining the blue vs red blood for the purposes of explaining the blood gasses, but just a quick reminder to anyone that doesn't know any better...blood is never blue lol. Deoxygenated blood is a dark red color and oxygenated blood is a brighter red. But never blue 😣

I commented on my iPhone, so I just used one of my emojis haha. Veins look blue (or sometimes green) depending on what color tone your skin is. But basically it all has to do with what color wavelengths your skin absorbs. I can't remember if it's because your skin absorbs more blue than red, or the other way around. But all in all, whether it's venous blood or arterial blood, it's some shade of red due to the heme (iron carrying) molecules that make up hemoglobin! Hope this helped :)

You’ve made this so easy to understand, thank you. Now I understand how the heart works for my A&P exam next year :)

your MS PAINT skills rule.

first time I watched this video, God knows I was confused as hell, maybe it was because I actually did not want to learn, this was two months ago. Then today am back focused and ready with my test book right next to me and I can tell you one thing. If you are not lazy this is the easiest way to learn about the heart. I don't know why it took me so long to get this. *sigh*

Seriously! Why can't teachers be more like this guy! Makes my life easier..... Thank u khan!

One of the best videos I've reviewed for the heart. It is really helpful in giving you that picture of the heart to easily remember all the chambers and functions! Thank you for this! It helped me ace my test!

Really a beautiful organ. Just compare this to an insect heart, which has an open circulatory system - blood is not confined to vessels but circulates freely inside insect. There is one main vessel that runs along the length of the insect. It absorbs the blood in the insect's abdomen and then forces it up towards the head. All that adds up to a few inches of vessels in the largest insects... the average adult human has about 60000 miles of blood vessels. What a contrast! Both systems work incredibly well.

Love this diagram! And your attention to detail! I re-watched it a couple of times while preparing for a quiz! Thank you for taking your time and posting this! However, I just wanted to let you know that blood is never blue. It is always red, they just labeled it blue v. red for teaching purposes.

Thanks for making me feel like I'm watching this out of curiosity and not because I have a test over this tomorrow, it made me feel better ;)

I watched a one hour university lecture twice, and another 2 seperate youtube videos. This one was the most helpful by far. Thank you

When hemoglobin is carrying oxygen, it's chemical properties change and it gives your blood the reddish color you see when you cut your leg. When it is not carrying oxygen, hemoglobin gives your blood a bluish tint (it's not blue like the sky, but closer to a dark purple).
