Describe in detail the circulation flow of blood through the heart. There are 8 steps.

1. Blood comes through the superior and inferior vena cava
2. Enters the right atrium: Is deoxygenated and has high CO2 content
3. Moves into the right ventricle
4. Pumped into the lungs, CO2 is released and O2 is picked up
5. Back from the lungs into the left atrium
6. Goes into the left ventricle
7. Into the AORTA and out into the body
8. Veins bring the blood back to the heart and repeats the process
