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.
1 The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs. 2  The left atrium receives oxygen-rich blood from the lungs and pumps it through the mitral valve to the left ventricle. 3  The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.lood travels through your heart and lungs in four steps: 1  The right atrium receives oxygen-poor blood from the body and pumps it through the tricuspid valve to the right ventricle. 2  The right ventricle pumps the oxygen-poor blood through the pulmonary valve to the lungs.
