1. colour the path of oxygenated blood red and deoxygenated blood blue.
2. 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 ________ __________

Explanation:

These questions are based on basic human circulatory system facts, typically covered in biology education focused on the heart and blood flow.

Answer:

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 cells are houses.
4. All the blood in your vessels could stretch around the earth 2.5 times.
5. When the left side of your heart squeezes, blood goes to your entire body (systemic circulation).
6. I have more [ red blood cells ] in my bloodstream.
7. Which lives longer? [ white blood cells ]
8. It takes 10 sec. for blood to go around your body when you're exercising.
9. Exercising brings more oxygen-rich blood to your muscles.
10. Your heart pumps 7,000-10,000 liters per day!
11. During your lifetime, your heart will beat about 2.5-3 billion times.
12. Labeling guide (matching terms to the diagram):

• Top large vessel: Aorta (2)
• Vessel connecting lungs to left heart: Pulmonary Vein (1)
• Upper left heart chamber: Left Auricle or Atrium (LA)
• Upper right heart chamber: Right Auricle (RA)
• Lower left heart chamber: Left Ventricle (LV)
• Lower right heart chamber: Right Ventricle (RV)
• Curved structures near the heart: Lungs
• Vessel connecting right heart to lungs: Pulmonary Artery (4)
• Bottom large vessel: Vena Cava (3)
• Outer circular structure: Tissues of the body

1. Colour guide:

• Oxygenated blood (Aorta, Pulmonary Vein, left side of heart): Red
• Deoxygenated blood (Vena Cava, Pulmonary Artery, right side of heart): Blue

1. Arrow direction guide:

• Into heart: Vena Cava → Right Auricle → Right Ventricle; Pulmonary Vein → Left Auricle → Left Ventricle
• Out of heart: Right Ventricle → Pulmonary Artery → Lungs; Left Ventricle → Aorta → Body Tissues

1. Blue Blood or Red Blood?

• 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.
