d. blood moves from the heart into arteries and into smaller vessels and then back into larger vessels as it makes its way back to the heart.

Explanation:

A closed circulatory system is a system in which blood is separated from the interstitial fluid as it circulates in the blood vessels. In a closed circulatory system blood circulates in one direction that is from the heart and then then returns to the heart again after circulating around one of two routes of circulation. A closed circulatory system can be observed in vertebrates, annelids, mollusks.
