<P> Deoxygenated blood leaves the heart , goes to the lungs , and then re-enters the heart ; Deoxygenated blood leaves through the right ventricle through the pulmonary artery . From the right atrium , the blood is pumped through the tricuspid valve ( or right atrioventricular valve ) , into the right ventricle . Blood is then pumped from the right ventricle through the pulmonary valve and into the main pulmonary artery . </P>
