How might a hole between the sides of the heart affect the functioning of the circulatory system?

Answer:

Since oxygen-rich and oxygen-poor blood would mix, the cardiovascular system may not be able to deliver enough oxygen to the body

Explanation:

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.
