Expert Answer:

A closed circulatory system is one in which blood circulates only inside blood vessels.

Humans have a closed circulatory system because the blood is always enclosed in vessels and the heart while circulating throughout the body. The blood travels through arteries and veins and carries important molecules throughout the body and is always confined.
