A Closed Circulatory system-Is a blood circulation system in which blood moves through the body in closed vessels.

In the closed circulatory system, the blood is confined to vessels. The heart pumps blood to vessels through smaller vessels which go to the organs. This system has a more efficient way of transporting blood then an open circulatory system.

Some animals that have this systems include earthworms, squids, octopus, and all vertebrates, like humans.

Closed circulatory system is to supply nutrients to body tissues and uptake waste products the tissues accumulate. The function is the same as an open circulatory system, the only difference is the way they work. Open systems are more difficult to understand, but instead of having blood contained in vessels in which nutrients diffuse across, they blood is pumped into body cavities and can diffuse directly into tissues.
