This prevents blood from flowing backward into the atria while the ventricles contract.eft Side. Blood flows from your left atrium into your left ventricle through the open mitral valve. When the ventricles are full, the mitral valve shuts. This prevents blood from flowing backward into the atria while the ventricles contract.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated and then returns to the left atrium through the pulmonary veins. Left Side of the Heart. The pulmonary veins empty oxygen-rich blood from the lungs into the left atrium of the heart. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
