Practice Question

What is the correct order of deoxygenated blood flow as it enters and then exits the heart?

Answer Choices:

Correct Answer:

Enters the superior or interior vena cava; exits the pulmonary arteries

Rationale:

✏️ Deoxygenated blood enters the right atrium of the heart via the superior and inferior vena cava.

✏️ It then passes through the tricuspid valve into the right ventricle.

✏️ From the right ventricle, blood is pumped through the pulmonary valve into the pulmonary arteries.

✏️ These arteries carry the blood to the lungs for gas exchange and oxygenation.

✏️ This pathway confirms that venous blood enters via the venae cavae and exits the heart through the pulmonary arteries.
