Correct Answer is A
Explanation
Veins have valves that ensure blood flows toward your heart. They work hard, against gravity, to bring the blood that flowed down via arteries back up to your heart. This prevents the backflow of blood.
Choice B rationale:
Veins do not aid in the redirection of blood flow. Their primary function is to return deoxygenated blood from the body back to the heart.
Choice C rationale:
The function of preventing oxygenated blood from mixing with unoxygenated blood is not performed by the valves in veins but by the structure of the circulatory system itself.
Choice D rationale:
While veins do aid in the circulation of blood, they do not aid in the pumping of blood. The pumping action is performed by the heart.

The spleen does play a role in immunity, but it has other functions as well.
