Pathway of Blood through the Heart
Period_______
Directions: Cut and paste the descriptions in the correct order that blood takes
through the heart. Begin with blood entering the heart. Number the steps.
1. Deoxygenated blood enters the heart through the Superior Vena Cava and the
Inferior Vena Cava.
2. Deoxygenated blood fills the Right Atrium.
3. Both atria walls contract and the deoxygenated blood goes down to fill the Right
Ventricle.
4. Both ventricles contract and deoxygenated blood leaves the Right Ventricle
through the Pulmonary Arteries.
5. Deoxygenated blood enters the lungs, releases excess carbon dioxide and picks
up oxygen to become Oxygenated blood.
6. Oxygenated blood travels back to the heart through the Pulmonary Veins.
7. Oxygenated blood enters the heart and fills the Left Atrium.
8. Both atria contract and oxygenated blood travels down to fill the Left Ventricle.
9. Both ventricles contract and oxygenated blood leaves the heart through the
Aorta.
