I'm glad this helped. I don't know of any other embryology videos that have the same qualities as this one: concise narration synchronized with clear animation. This heart video wasn't my work: it was made many years ago by Drs. Blandau and Rushmer. My only role was to restore it. Right now I'm working on an animation to show folding of the embryo. It's slow work! Bob Acland
Komandor Cliff Yeah, a person can praise anything they want to. It doesn’t mean I’ll agree with it most of the time, but it’s their choice. Only case I’m in favor of intervening is in extremist ideologies such as neo nazism. I don’t agree with the way in which you belittled the other dude’s belief in order to get your point across, but I do agree with you that they shouldn’t be telling others what they can and can’t praise
@@dogzrule4every1 the level of shit talk going over here if absurd..why cant people just ignore and be in peace with one self..accepting and denying the existence of some other people and their voices raise the unnecessary issue ..if someone else ideology is practically doing no harm then why to indulge in shitty discussion
Beautiful. Surprisingly, this video made in 1951 supersedes any modern 3-D video in visualizing and conceptualizing the embryological development of the heart. A must watch for those struggling to understand this process.
I find 3D medical illustrations and animations very cool, but i think that 2D old fashioned stuff is more educational. Less flashy but more educational. I am happy to see that others also think like this.
Plz, i'm really interested in embryology, tell me wich book should i read. I'm an advanced student of molecular biology and i'm used to read heavy stuff, so bring all you've got.
The original video has helped me so much... this is an awesome restoration... A big thanks to all involved in making both the videos.. -----A very grateful medical student....
Got tears in my eyes after watching this. For months i tried to understand this crap from books which was almost impossible to visualize, this video helped me understand that in a mere 10 minutes! God bless the person(s) who made this.
omg 5 years in med school...and 3 in residency... nd i have never understood this...thank u thank u .... this is a really awesome, sensible and easy to understand aimation. i m gonna recommend it to everybody.
Dr. Robert Acland, you are an absolute inspiration. Your teachings have followed me throughout my entire educational endeavor which has assisted me in publishing medical illustrations, anatomical dissections, and of course... research. Hat is off to you sir!
Transcription of the video: Initially, the heart consists of a simple tube. It’s anchored at one end by the differentiating arterial trunks and at the other by extensive venous channels which drain into the atrium. Being fixed at both ends, the cardiac tube grows rapidly in length and the embryonic ventricle is bent into a loop to the right of the midline. As development continues, the ventricular region swings back to the midline, and expands and grows in length to cover the atrium and great veins. Extensive sacculations projecting laterally will ultimately become the right atrium and left atrium. The future left ventricle lies to the left of the interventricular groove, and the embryonic right ventricular or bulbo-conus region communicates with the truncus arteriosus. A four-chambered heart is formed from this convoluted tube by the development of three septa partitioning the atria, the ventricles and the truncus arteriosus. Although these septa develop simultaneously, they will be considered individually. By viewing the heart from the right side, partitioning of the atria and ventricles can be more easily visualised. Externally, a deep groove separates the atrium from the ventricle. Within the heart, the atrioventricular groove appears as a deep invagination which constricts the atrioventricular canal at its waist. The canal becomes divided along its longitudinal axis by two partitions growing from the walls of the two common chambers toward the auricular-ventricular junction. Endocardial cushions extend from opposite sides of the atrio-ventricular aperture and ultimately fuse into a column, dividing the channel between the atrium and ventricle. From the interventricular ridge, a proliferating muscular septum advances across the common ventricle toward the base of the heart. Simultaneously, the interatrial septum rapidly grows toward the endocardial cushions, progressively constricting the foramen between the atrial chambers, the foramen primum. Before the foramen primum becomes obliterated, a new opening appears, high on the interatrial septum. The timely development of this orifice, the foramen secundum, provides uninterrupted shunting of blood from the right atrium directly into the left. Another interatrial septum, the septum secundum, develops from a ridge just to the right of the septum primum, and extends down like a curtain over the interatrial fenestration. The advanced edge of the septum secundum forms the foramen ovale, with the septum primum acting as a unidirectional flutter valve. Thus, blood can flow only from the right atrium to the left. To recapitulate, the common atrioventricular canal is partitioned by the simultaneous proliferation of the endocardial cushions, the muscular interventricular septum, and the interatrial septum. The septum secundum produces the foramen ovale, with the septum primum acting as a membranous valve. An opening persists between the ventricular cavities. Closure of this interventricular foramen awaits the elaboration of a complex spiral septum, which splits the truncus arteriosus and conus region into the aorta and pulmonary artery. The formation of this partition is more clearly seen if the heart is turned by 45 degrees. Originally, the right and left ventricles share a common outflow channel, the truncus arteriosus, which gives rise to the aortic arches. The truncus arteriosus is presented schematically as a transparent cylinder. The bifurcation of the truncus arteriosus, illustrated here, represents two of the aortic arches. The fourth aortic arch forms the aorta and the sixth is the origin of the pulmonary artery. A pair of ridges, which develop at the bifurcation, spiral down the truncus arteriosus. They fuse along the axis of the cylinder to produce a single spiral septum, extending down towards the ventricles. The interventricular foramen is obliterated by masses of endocardial tissue from the ventricular septum by the endocardial cushions and by the spiral aortic septum. The partitioning of the heart into its component chambers and corresponding arteries is now complete. The significance of the spiral aortic pulmonary septum is more readily-appreciated in a frontal view of the heart. Aortic pulmonary septum executes a spiral of 180 degrees and swings into line with the interventricular septum. This process accounts for the manner in which the aortic and pulmonary trunks are entwined in the fully-developed heart. Blood from the left ventricle enters the aorta, which passes to the right, behind the pulmonary artery. Blood from the right ventricle enters the pulmonary artery, which passes in front of the aorta, turning posteriorly on the left side of the mediastinum. Venous blood from the superior vena cava, and the inferior vena cava flows through the right atrium and into the right ventricle. It’s ejected into the pulmonary artery, where a major portion continues through the ductus arteriosus into the descending aorta. Resistance to flow through the collapsed lungs is so great that only a small quantity of blood enters the pulmonary arteries. A correspondingly small amount of blood is returned through the pulmonary veins into the left atrium. Oxygenated blood from the placenta enters the inferior vena cava, but tends to stream across the right atrium through the foramen ovale, and into the left atrium to supplement the scanty pulmonary venous return. This mixture of venous and oxygenated blood enters the left ventricle and is pumped into the aorta, from which the carotid arteries arise to supply the brain. Through the descending aorta, partially-oxygenated blood is distributed to the lower portions of the body. This circulatory pattern persists throughout the remainder of fetal development. Within a very few minutes after delivery into the external world, the supply of oxygenated blood from the placenta is interrupted. If the infant is to survive, respiratory exchange in the lungs must be promptly established. As the lungs become inflated, the resistance to pulmonary blood flow is markedly reduced. Constriction of the ductus arteriosus diverts the entire right ventricular output into the pulmonary circulation. Oxygenated blood returning from the lungs is distributed through the systemic circulation. When the pressure in the left atrium exceeds that in the right atrium, the valvular is pressed over the foramen ovale, and partitioning of the heart is functionally complete.
I cannot express how thankful I am about this video. This saved valuable hours of my time that I would have spent on understanding this process. Thank you so much.
Your soothing voice and careful enunciation calms my Cardiophysiology-induced rage. This is a wonderful resource and a far preferable alternative to confusing diagrams and cross-sections. Thank you so very much.
wow....what a video. Just exquisite attention to detail with multiple angles and in perfect logical order. U don't find this kind of education anymore. I've LITERALLY never been able to understand heart embryology until now
When medical education was about knowledge, not profit. This video singlehandedly taught me Heart embryology in less than 5 minutes at 2x speed. Too many teachers out there now bitten by the pedagogical but infected poor didactics syndrome. The latter bit on fetal circulation 6:44 is concise and bite-size. Perhaps a small word on adult anatomical remnants would have rounded it off. But overall, superb!! We need to get back to these simple teachings.
after watching many old videos explaining medical stuff, im more convinced that lecturers and companies explain everything in a bad way so students spend more on different resources, GREAT video thanks for sharing
thanks to dr ryan i found this video, thank you doctor rushmer and blandau whereever you are i hope yall are happy, you made our life easier. GOD BLESS
The team involved in launching this masterpiece deserves bows, you are educating us for sure, maybe some teachers need to be educated about how to teach❤
Thank you, Doctor Acland! I'd recognise that voice anywhere. And even though you are no more, your voice guides me through my journey to becoming a doctor.
Sir you are a blessing. God Bless you. Being a MS 1 student, the challenges associated with the rigor of the material are there, but through your anatomy and youtube videos, you have made it easier. My roommates and I salute your efforts. Take care!
Dr. Acland - I really appreciate the video! Fetal cardiac development was this big scary monster to me, but this video has really helped me understand it! I have to admit I was totally lost watching this the first time, but after lecture, lab, and watching this several more times it makes sense now! As a visual learner who has trouble reading textbooks without pictures, thank you so much!
Respected Acland sir this is Sachin from cochin (remember) this is really something! its a classical example of how imaginative people are, worth watching and sharing. Its superior to nowadays animation which are full of effects alone.
Best vid ever on heart development... Big thanks...!!!! ❤... This is way far clear....Marvelous how with meagre effect could explain so well which present tym effect and technology could nt beat!!!
This video turned a rediculously complicated lecture from some phd student who taught it horribly, to something I easily understand and can digest. Thanks!
I have watched this 3 times, now is my 4th, and every time I watch it I think I understand everything there is to know about heart development. Until I forget it and need to watch it again, that is. Thanks from AUSTRALIA. Also, Bob Acland thanks for doing this remaster (I remember watching it a couple of years ago before you did this) and also please please bring out that Embryology video soon... I really really need it :)
thank you so much for this clear description ... i have got a headache trying to understand what is written in the book ; but now it all came into my mind as simply as watching a cartoon
Thank you for this restoration which is the best 10 minutes I have spent understanding fetal heart development. Hands down best, clear, logical views of the sequence of events.
Just about to start my cardio block in a few weeks time and was recommended to get a good grip on embryology early. So glad I found this, HOLY COW! Everything makes so much sense and it will be so much easier to understand cardio now 😭
Thank you for your work, watching the animation is much better and easily understood than reading it. However to me the development of the heart remains an unbelievable and amazing process.
this video is clarifying. so perfect.! very well explained . awesome video. made my life complete. gods creation.... amazing. excellent. thanks grandpa. hard to believe this stuff was made in 1951. simply the best classic. greatest video i've ever seen . more videos please.
Frankly speaking I never understood the pathology behind TOF and transposition of great arteries Read inderbeer singh, langman embroyolgy but never understood But this video has explained 100 time better than any other video or any book
It's 2023 and this video from 72 years ago is the best I've found on the subject. Besides, it's not even my native language.
funny how a 1951 video explains this better than a 2013 lecturer
So true, I've been reading the shit of Carlson's embriology and I hadn't understood a shit until now with this video.
Well said
Holds true in 2017
or a 2017 lecture
agree
I'm glad this helped. I don't know of any other embryology videos that have the same qualities as this one: concise narration synchronized with clear animation. This heart video wasn't my work: it was made many years ago by Drs. Blandau and Rushmer. My only role was to restore it.
Right now I'm working on an animation to show folding of the embryo. It's slow work!
Bob Acland
That was absolutely brilliant. Love it
Oh my God please post the video on folding. It would really help
You did a noble job uploading this gem to youtube!👏👏
And yet you are collecting ad revenue on it...
old masters know how to explain anatomy and embryology. Take a bow in front of these masters
Peter Tiesto well said
Tak a bow in front of god only

This video deserve an Oscar Award!
Open the door , this is FBI😂😂😂
Literally literally literally
Yeah, but he doesn’t know what a try tricuspid value or a bicuspid valve lol if you’re trying to learn this guy, I wouldn’t suggest it

2 years gone by and this is still the best video on the internet on heart embryology!
My professor is still using this in anatomy class in 2019. I have not found a better explanation so far...
I am professor of Human Embriology and this video was a wonderful tool to teach the development of the cardiovascular system in my classes! Great
Plz, i'm really interested in embryology, tell me wich book should i read. I'm an advanced student of molecular biology and i'm used to read heavy stuff, so bring all you've got.
@@besacciaesteban langman human embryology my favourite or you can read KLM human embryology too
yo 1951 lectures were legit

One of the best embryology lectures ever... No one could explain it better. Pure classic 🖤💪🏼
Absolutely sensational video. I'm a cardiologist and I've never seen this explained so eloquently.
Wow , what today's lecturer can't do , you did it in 1951, so methodical , pls put videos on cardiac embryology in detail with structure and CHD
70 years later, i say thank you
I NEVER understood this until now. THANK YOU.

Hands down, without a doubt the greatest video I have seen explaining this topic. Amazing. thank you for sharing!
89 slides and 3 hours of lectures couldn't teach this well. It's awesome!!!!
this will always be my favorite video on all of youtube
Thank you Dr. Madhavi mam for showing this video to a bunch of naive pediatrics residents ❤
Such an iconic voice for medics , calms you and at the same time reminds you of all the times you slept when you were watching this in bed
2022 and still nothing can beat this.
This is the best heart developement video. An it's so old! Also, Mr. Acland narrating this is just pure bliss
wow....what a video. Just exquisite attention to detail with multiple angles and in perfect logical order. U don't find this kind of education anymore.
I've LITERALLY never been able to understand heart embryology until now
I usually don't comment but Sir , your video had compelled me to appreciate your effort . Marvellously explained ! Hats off !

it's amazing what a good 10 mins of explanation can do, better then d hours I spent on daigrams
xd
Hats off to all who made this. This is real gem. #Respect
Wow... Too amazing... After 4 yrs of medical School, i understand it now...
That's excellent as 100 books of anatomy of human heart and 1000 lectures about normal development of human heart
Fearful and wonderful made
Best vid ever on heart development... Big thanks...!!!! ❤... This is way far clear....Marvelous how with meagre effect could explain so well which present tym effect and technology could nt beat!!!
You must be awarded with noble prize...what an animation...what a video..just anazing amazing and amazing...nothing to say😍😍
Wow, what a lecture! Human body development is simply amazing, it's almost moving... life is incredible.
this is one of the coolest videos i've ever watched
Thank you Dr. Acland! You are such an inspiration and you are truly missed!
this is the best embryology video i have ever seen
This video turned a rediculously complicated lecture from some phd student who taught it horribly, to something I easily understand and can digest. Thanks!

Amazing video ! Very helpful. Perfectly presented. This video from 1951 is much better than any book of the present time.
His voice is so relaxing... I felt so sleepy.
Thank you for this restoration which is the best 10 minutes I have spent understanding fetal heart development. Hands down best, clear, logical views of the sequence of events.
Very nice animation. Very clear explanation. Thank you for posting this!
if it wasn't because of this video I would have not passed my first modular exam in medicine!thanks a million! :D
Just about to start my cardio block in a few weeks time and was recommended to get a good grip on embryology early. So glad I found this, HOLY COW! Everything makes so much sense and it will be so much easier to understand cardio now 😭
Made in 1951 but still the best explanation of the embryonic heart to this day!
hard to believe this video was made decades ago very good video very usefully
this is a work of art
M really grateful to the Doctors for teaching it in such a beautiful yet so simply. It's Excellent! :)
i have finally cleared my doubts...thanks ...old is gold video
That was really helpful, thank you so much for going to all that effort to restore that film and turn it digital!
SPEECHLESS
THIS GAVE THE PERFECT VISUALISATION
THANK YOU VERY MUCH
الحمد لله
❤❤❤❤❤
Thank you for your work, watching the animation is much better and easily understood than reading it. However to me the development of the heart remains an unbelievable and amazing process.
My anatomy book didn't explain this well at all. Thanks for making something so complex easy to understand!
A precious masterpiece from the 20th century
This explanation is beyond amazing. Thank you!
Thank you so much for posting this.
Wow! Crisp and clear explanation. Thank you!
amazing animation !!!! made me understand in 9 min what 1 hour of lecture could not...
this video is clarifying. so perfect.! very well explained . awesome video. made my life complete. gods creation.... amazing. excellent. thanks grandpa. hard to believe this stuff was made in 1951. simply the best classic. greatest video i've ever seen . more videos please.
Frankly speaking I never understood the pathology behind TOF and transposition of great arteries
Read inderbeer singh, langman embroyolgy but never understood
But this video has explained 100 time better than any other video or any book
So sophisticated and clearly explained.
This is SO aesthetic
Amazing vid, studying for a block exam that includes development of the heart right now and this is definitely going to be a huge help.
This video helped me in 2024, 73 years after it was made.
This was very helpful in illustrating development of the heart. Thanks for sharing.
Still looking this video in 2017. This is a great video.
best heart development video ever
Truly Might be the best explanation ever !!!
Simple animation and clear explanation made life easy!Thank you so much
Wonderful video. Suggested by Dr. Purcell, one of our favorite professors at UMHS-St. Kitts. Thank you!
