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.
The right atrium and the right ventricle pump blood into the lungs via the pulmonary artery. The blood picks up oxygen in the lungs and returns to the heart through the left atrium and left ventricle. The left atrium pumps blood through other parts of the heart and the rest of the body. The oxygenated blood circulates through the body. Deoxygenated blood from the body goes back to the right atrium where the process begins again. The aorta and the coronary arteries play an important role in providing oxygenated blood to the rest of the heart. The coronary arteries help move oxygenated blood from the aorta to the heart. The aorta provides oxygenated blood from the left atrium and left ventricle to the rest of the body.
