    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.

    Where does the blood from the left atrium go? Does it continue to the LV and then into the aorta?
