As the left ventricle contracts, the mitral valve closes and the aortic valve opens. The closure of themitral valve prevents blood from returning to the left atrium, and the opening of the aortic valve allows the bloodto flow into the aorta and from there throughout the body.lood Flow The heart's cycle begins when oxygen-poorblood from the body flows into the rightatrium. Next the blood flows through the rightatrium into the right ventricle, which serves asa pump that sends the blood to the lungs.Within the lungs, the blood releases wastegases and picks up oxygen.
Overriding Aorta. This defect occurs in the aorta, the main artery that carries oxygen-rich blood from the heart to the body. In a healthy heart, the aorta is attached to the left ventricle. This allows only oxygen-rich blood to flow to the body.In tetralogy of Fallot, the aorta is located between the left and right ventricles, directly over the VSD. As a result, oxygen-poor blood from the right ventricle flows directly into the aorta instead of into the pulmonary artery.n a healthy heart, the aorta is attached to the left ventricle. This allows only oxygen-rich blood to flow to the body. In tetralogy of Fallot, the aorta is located between the left and right ventricles, directly over the VSD.
