Arrange the steps of blood circulation in the correct sequence by numbering the items 1-10: 1. Deoxygenated blood enters the heart through the superior and inferior vena cavae. 2. The right atrium contracts and opens the tricuspid valve. 3. Deoxygenated blood flows from the right atrium to the right ventricle. 4. The right ventricle contracts and opens the pulmonary valve. 5. Deoxygenated blood flows into the pulmonary artery. 6. Blood flows into branches of capillaries in the alveoli to receive oxygen. 7. Oxygenated blood proceeds into the pulmonary vein. 8. Oxygenated blood flows into the left atrium. 9. The left atrium contracts and opens the mitral valve. 10. Oxygenated blood flows into the left ventricle. 11. The left ventricle contracts and opens the aortic valve. 12. Oxygenated blood flows into the aorta. 13. Branches of arteries deliver the oxygenated blood to different parts of the body. 14. Oxygen from the blood is absorbed by the cells.
