  1. The blood first enters the right atrium.
  2. The blood then flows through the tricuspid valve into the right ventricle.
  3. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
  4. The pulmonary artery carries blood to the lungs where it “picks up” oxygen and then leaves the lungs to return to the heart through the pulmonary vein.
  5. The blood enters the left atrium, then descends through the mitral valve into the left ventricle.
  6. The left ventricle then pumps blood through the aortic valve and into the aorta, the artery that feeds the rest of the body through a system of blood vessels.
  7. Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava
  8. . This blood carries little oxygen, as it is returning from the body where oxygen was used
  9. The vena cavas pump blood into the right atrium and the cycle of oxygenation and transport begins all over again.
