step 2
the blood flows through the right atrium. -
step 3
the blood flows throgh the tricupsid valve into the right ventricle where it gets pumped to the pulmonary artery passing the pulmonary valve. -
step 4
the blood is oxygenated by the lungs and returned back to the heart through the four pulmonary veins. -
step 5
the blood enters the left atrium and the to the left ventricle passing the bicupsid valve. -
step 6
