Question 35

How does blood flow through the heart

Answer 35

1. Oxygen-poor blood enters the right atrium, via the superior vena cava and inferior vena cava. 2. The blood moves through the tricuspid valve into the right ventricle. 3. The blood is then pumped through the pulmonary valve, and into the pulmonary artery. 4. The blood moves through the pulmonary artery and into the lungs. 5. The blood exchanges carbon dioxide for oxygen and is then carried back to the heart via the pulmonary veins where it enters the left atrium. 6. The now oxygen-rich blood is pumped through the mitral valve and into the left ventricle. 7. From here the blood is pumped through the aortic valve and into the aorta, where it is then sent to the rest of the body.
