Name: ______________________ Class: __________ Date: _______________________ The Pathway of Blood through the Heart Starting with DEOXYGENATED BLOOD at the RIGHT ATRIUM, detail the pathway of blood (structures and type of blood) … Structures 1. Blood moves from the Right Atrium through the Tricuspid Valve into the Right Ventricle. 2. Blood moves from the Right Ventricle through the Pulmonary Valve into the Pulmonary Artery. Type of Blood (Oxygenated or Deoxygenated) Deoxygenated Deoxygenated 3. Blood travels through the Pulmonary Artery into the right and left lungs. Deoxygenated 4. In the lungs, blood cells drop off carbon dioxide and pick up oxygen. Deoxygenated à Oxygenated 5. Blood travels back to the heart through the Pulmonary Veins, and into the Left Atrium. Oxygenated 6. Blood moves from the Left Atrium through the Mitral Valve into the Left Ventricle. Oxygenated 7. Blood moves from the Left Ventricle through the Aortic Valve into the Aorta. Oxygenated 8. Blood travels through the Aorta to the rest of the body, where it drops off oxygen and picks up carbon dioxide. 9. Blood travels back to the Right Atrium of the heart, through the Superior and Inferior Vena Cava, to start the whole process again. Oxygenated à Deoxygenated Deoxygenated
