Left Auricle or Atrium (LA)
Left Ventricle (LV)
Lungs
Pulmonary Artery (4)
Pulmonary Vein (1)
Right Auricle (RA)
Right Ventricle (RV)
Vena Cava (3)
Tissues of the body

blue.
14. Use arrows to indicate blood flow direction.
Blue Blood or Red Blood?
Rule #1: All flow Away from the heart.
Rule #2: always lead to the heart.
Rule #3: All Arteries carry blood EXCEPT the
Rule #4: All Veins carry blood EXCEPT the

Answer 1

Here are the answers and labeling hints:

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 the cells (tissues) of the body.
4. All the blood in your vessels could stretch around the Earth about 2.5 times (≈100,000 km / 60,000 miles).
5. When the left side of your heart squeezes, blood goes to your body (systemic circulation).
6. I have more red blood cells in my bloodstream.
7. Which lives longer? red blood cells (≈120 days)
8. It takes about 20 seconds for blood to go around your body when you’re exercising (at rest ~60 seconds).
9. Exercising brings oxygen (and nutrients) to your muscles.
10. Your heart pumps about 7,000 liters per day (roughly 2,000 gallons).
11. During your lifetime, your heart will beat about 2.5–3 billion times (depends on heart rate and lifespan).

12. Labeling the diagram (place these names in the obvious positions on the heart diagram):
- Pulmonary Vein — label 1 (carries oxygenated blood from lungs to left atrium)
- Aorta — label 2 (carries oxygenated blood from left ventricle to the body)
- Vena Cava — label 3 (returns deoxygenated blood from the body to the right atrium)
- Pulmonary Artery — label 4 (carries deoxygenated blood from right ventricle to the lungs)
Also label chambers and tissues:
- Left Auricle/Atrium (LA) — upper left chamber receiving blood from pulmonary veins
- Left Ventricle (LV) — lower left chamber pumping into the aorta
- Right Auricle/Atrium (RA) — upper right chamber receiving from the vena cava
- Right Ventricle (RV) — lower right chamber pumping into pulmonary artery
- Lungs — at the side, connected to pulmonary vessels
- Tissues of the body — downstream of the aorta/capillary network

13. Colour the path of oxygenated blood red and deoxygenated blood blue.

14. Use arrows to indicate blood flow direction.

Blue Blood or Red Blood? (rules)
- Rule #1: All Arteries flow away from the heart.
- Rule #2: All Veins always lead to the heart.
- Rule #3: All Arteries carry oxygenated blood EXCEPT the pulmonary artery (it carries deoxygenated blood to the lungs).
- Rule #4: All Veins carry deoxygenated blood EXCEPT the pulmonary vein (it carries oxygenated blood from the lungs).

(You can also note: blood is never truly blue — venous blood is dark red; veins only appear blue through the skin.)
