Do Humans Have A Closed Circulatory System. Instead of a heart, there are blood vessels that act as pumps to force the blood.

Circulatory Systems A Level Notes from alevelnotes.com
Humans have a closed circulatory system, which is exactly how it sounds: Difference between open and closed circulatory system. In this type of system, there is neither a true heart nor capillaries as are found in humans.
