Circuitry of the Cardiovascular system
1. Oxygenated blood returns from the lungs to the left atrium via the 6. Blood returns to the right atrium via superior and inferior vena
pulmonary veins cava.
2. Blood flows from the left atrium to the left ventricle through the mitral 7. Blood flows from the right atrium to the right ventricle via the
valve. tricuspid valve.

3. Blood is pumped from the left ventricle into the aorta through the aortic 8. Blood is pumped from the right ventricle into the pulmonary
valve. artery through the pulmonary valve.
4. Blood is distributed to various organs via arteries. 9. In the capillaries of the lungs, oxygen (O2) is added to the blood
5. Unoxygenated blood flow from the organs is collected in the vein and CO2 is removed from the blood.
