Question

what will happen if septum is not present between the heart​

Answer 1

Answer:

The hole (defect) occurs in the wall (septum) that separates the heart's lower chambers (ventricles) and allows blood to pass from the left to the right side of the heart. The oxygen-rich blood then gets pumped back to the lungs instead of out to the body, causing the heart to work harder.

Answer 2

Answer:

Explanation:

Blood that should flow from the atrium to the ventricle instead flows through a hole in the septum from the left side of the heart to the right, and blood flow to the lungs increases. Small holes can go undetected until adulthood.
