Explanation:

For Question 3:

• The left ventricle pumps blood out of the heart, not into it.
• The aorta carries oxygenated blood away from the heart to the body.
• The superior vena cava brings de - oxygenated blood from the upper body to the right atrium of the heart.
• The inferior vena cava brings de - oxygenated blood from the lower body to the right atrium of the heart. So blood enters the heart from the body through both the superior and inferior vena cava.

For Question 4:

• Pulmonary veins carry oxygenated blood from the lungs back to the heart.
• Pulmonary arteries carry de - oxygenated blood from the heart to the lungs.

Answer:

Question 3: E. C and D
Question 4: B. the pulmonary arteries
