Step 1: Label Your Structures Aortic arch Superior Vena Cava Pulmonary Trunk (Arteries) Pulmonary veins Left Atrium Pulmonary veins Tricks to Remember: Arteries = away Veins = into Right Atrium Tricks to Remember: Blood from body is blue Blood from lungs is red Left Ventricle Right Ventricle Dorsal Aorta Posterior Vena Cava

Step 2: How does blood come into the heart from body? 1. De-oxygenated blood moves from upper body through SVC & lower body through PVC 1 4 2. De-oxygenated blood moves into the Right Atrium 2 3. De-oxygenated blood gets into the Right Ventricle 4. De-oxygenated blood gets pumped into the Pulmonary Trunk (arteries) to go to the lungs 3

Step 3: How does blood come from the lungs into the heart & out to body? 5. Oxygenated blood moves from the lungs through Pulmonary veins 8 5 5 6 6. Oxygenated blood moves into the Left Atrium 7. Oxygenated blood gets pumped into the Left Ventricle 7 8. Oxygenated blood gets pumped into the Aorta to go to the body
