Answer:

closed circulatory system

Step-by-step explanation:

The blood is pumped through a closed system of arteries, veins, and capillaries. ... Still, blood can flow backward and the system is only slightly more efficient than the open system of insects. The closed circulatory system has more advantages over the open circulatory system.
