Khan Academy is like...the supplement to your diet. You should always stick to your main diet (books, lectures, groups and such), but Khan Academy is like a Supplement that boosts your diet tenfolds...Genious stuff, THANKS!

10 years later and this video still MADE my day!! thank you so much for the interesting explanation

[@jasperjohnson83]

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

[@rachellemullins693]

I just love how thorough you are. This stuff can be confusing but you explain it so well...and your illustrations are perfect.

[@mamaajasco3693]

Wow wow wow. This is too perfect. Thank you, God bless you.

[@GMR2PMF]

I have been listening to Khan for so many years. I used him first in calculus when getting my physics degree, and now in medical school. Thank Sal! you da man

[@kennymokuolu863]

[@florinpasca2000]

Amen!

[@rayyan108]

I just love the presenter, he is very organized, systematic and clear in how presents the material Thank you so much, may God bless you

[@maryvue5809]

thank you so much--i'm a nursing student and this has helped me understand the basics of fetal circulation as it relates to the pathophysiology of congenital heart defects. love it!

[@XSirApocalypseX]

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.
