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 aorta is the main artery that carries oxygen-rich blood pumped from the left side of the heart out to the body. 2  The coronary arteries are the other important arteries attached to the heart. 3  They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function. The pulmonary valve is in the right side of the heart, between the right ventricle and the entrance to the pulmonary artery, which carries blood to the lungs. 2  The mitral (MI-trul) valve is in the left side of the heart, between the left atrium and the left ventricle.
