Answer:
The correct answer is from the left side of the heart to the right side of the heart, that is, the oxygenated blood from the lungs is shunted back into the pulmonary circulation.
Explanation:
The congenital cardiac malformations known as acyanotic heart defects influence the ventricular or the atrial walls, large blood vessels, or the valves of the heart. The common reasons comprise maternal infections, genetic defects, or consumption of alcohol or drugs by the mother at the time of pregnancy.
The acyanotic heart defects are featured pathophysiologically by a left-to-right shunt that leads to right heart hypertrophy and pulmonary hypertension.
