- Oxygenated blood is ejected from the left ventricle through the aorta and on to the body organs and tissues where oxygen diffuses into cells and CO2 diffuses out of cells. The now deoxygenated blood travels back to the right atrium via the superior and inferior vena cava.
- Deoxygenated blood is pumped from the right ventricle into the right and left pulmonary arteries and into the lungs picks up oxygen and unloads carbon dioxide. The now oxygenated blood travels back to the left atrium via the pulmonary veins.
