10 years later and this video still MADE my day!! thank you so much for the interesting explanation
Wow! I have never had anything explained this clearly. Wow! From the way you started and connected everything, it’s just perfect. I have read this many years before and I thought I understood it or maybe I did before but it always slips away. There is no way this is ever going to slip away. Thanks man. Thank you
I've only used Netter myself, and it was one of my favorite books. =)
Wow wow wow. This is too perfect. Thank you, God bless you.
I just love how thorough you are. This stuff can be confusing but you explain it so well...and your illustrations are perfect.
perfect teaching. Now I understand it CLEARLY! Thank you. I pray God bless you, and meet you at your need too. Thanks!
Amen!

You are awesome! I use your lectures to improve my teaching skills and to learn things that either I had forgotten or never really understood. Thanks!

thank you so much! now I understad it.
I was luckily watched this video the night before my license exam. And for sure found the question related there. What a blessing. Thank you so much!
no word can explain how was I enjoyed it.
These videos are AMAZING! So SO helpful. I bet you rock at pictionary.
It's written in every Embryology book, that's not a big deal to understand this. Ductus arteriosus Botalli: Anastomosis between Lung truncus and Aorta. Foramen ovale: Hole between left and right Atrium. Both are physiological and close during brith normally (Foramen ovale closes due to increase of pressure in small circulation system, both septums (primum and secundum) are compressed to each other and close the Foramen ovale). Sometimes the obliteration and closure does not happen. Sometimes these Shunts are the only thing, that sustain the life of the newborn. It depends of the defect combinations. BTW: Before the Foramen ovale is created, the blood flows throw the Ostium primum and secundum to the other Atrium.
That was amazing. Very easy to understand and interesting. Awesome!
fantastic video! im not a med student (if all goes well i should be a pharmacy student this time next year) but starting watching this randomly and was blown away by how much i had learnt in a short period of time. i haven't been this genuinely intrigued or exited to learn more about subject simply out of interest in such a long time, so thank you very much for you fantastic video and please continue to do what you doing! :)
