Question

3 multiple choice 2 points blood from the systemic circuit enter the heart through what vessels (this blood is deoxygenated)? pulmonary arteries pulmonary veins aorta vena cava 4 multiple choice 2 points what blood vessels bring blood back to the heart from the lungs? vena cava pulmonary arteries pulmonary veins aorta

Explanation:

• Question 3: The vena cava is the vessel through which deoxygenated blood from the systemic circuit enters the heart. The pulmonary arteries carry deoxygenated blood from the heart to the lungs. The pulmonary veins carry oxygenated blood from the lungs to the heart. The aorta carries oxygenated blood from the heart to the systemic circuit.
• Question 4: The pulmonary veins bring oxygenated blood back to the heart from the lungs. The vena cava brings deoxygenated blood from the systemic circuit to the heart. The pulmonary arteries carry deoxygenated blood from the heart to the lungs. The aorta carries oxygenated blood from the heart to the systemic circuit.

Answer:

• Question 3: Vena Cava
