--- Quote ---i hav a doubt guys.
"in an unborn child, there is a hole in the septum b/w the left and right atria. What is the purpose of this?"
--- End quote ---
The septum is a tissue that prevents the deoxygenated blood in the right side of the heart from the oxygenated blood in the leftside of the heart
So if there is a hole then the oxygenated and deoxygenated blood mixes
Hope that helped
