Describe the steps of circulation in the heart
|
1. The right atrium sends deoxygenated blood into the right ventricle
2. The right ventricle forces the blood into the pulmonary arteries 3. The pulmonary artery sends the blood to the lungs. 4. In the lungs, the CO2 diffuses out of the blood and the oxygen diffuses in. 5. the oxygenated blood returns to left atrium. 6. the oxygenated blood is then pumped into the left ventricle 7. forced into aorta 8. spread to all parts of the body, then comes back to the right atrium |
