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!

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

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.

hello I got question in exam. "Explain the fetal circulation and its shunts." Is Foramen ovale right left shunt or left right shunt and is Ductus Arteriosus also right left shunt?
