Answer 1

Here are the answers and labeling instructions for the worksheet:

1. The systole is the big push and the diastole is the reloading push.
2. As you move away from the heart, your vessels get smaller.
3. If your capillaries are driveways, your houses are cells (the body’s cells/tissues).
4. All the blood in your vessels could stretch around the earth about 2.5 times.
5. When the left side of your heart squeezes, blood goes to your body (systemic circulation / tissues).
6. I have more red blood cells in my bloodstream.
7. Which lives longer? red blood cells (about 120 days for an RBC; most WBCs live shorter).
8. It takes about 20 seconds for blood to go around your body when you’re exercising.
9. Exercising brings more oxygen (and nutrients) to your muscles.
10. Your heart pumps about 7,000 liters per day.
11. During your lifetime, your heart will beat about 2.5 billion times (order of magnitude ~2–3 billion).

12. Diagram labeling (use these placements):
- Pulmonary Vein (1) — the vessel returning oxygenated blood from the lungs to the left atrium (LA).
- Aorta (2) — the large vessel leaving the left ventricle (LV) carrying oxygenated blood to the body.
- Vena Cava (3) — the large vein(s) returning deoxygenated blood from the tissues to the right atrium (RA).
- Pulmonary Artery (4) — the vessel leaving the right ventricle (RV) carrying deoxygenated blood to the lungs.
Also label the four heart chambers: Right Auricle/ Atrium (RA) (upper right), Right Ventricle (RV) (lower right), Left Auricle/ Atrium (LA) (upper left), Left Ventricle (LV) (lower left). Label Lungs on the side where pulmonary vessels go, and “Tissues of the body” where the aorta leads and the vena cava returns.

13–14. Coloring and arrows (follow this path; color oxygenated red and deoxygenated blue; add arrows for flow direction):
- From tissues → (blue) Vena Cava → RA → RV → Pulmonary Artery (4) → Lungs.
- In the lungs blood becomes oxygenated → Pulmonary Vein (1) (red) → LA → LV → Aorta (2) (red) → Tissues of the body → back to Vena Cava.

Blue Blood or Red Blood? (fill-ins)
Rule #1: All arteries flow away from the heart.
Rule #2: Veins always lead to the heart.
Rule #3: All arteries carry oxygenated blood EXCEPT the pulmonary artery.
Rule #4: All veins carry deoxygenated blood EXCEPT the pulmonary vein.

If you want, I can draw a simple ASCII diagram showing the flow with labels and arrows.
