Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)

segmented worms have a closed circulatory system.in a closed circulatory system, blood moves only within a connected network of tubes called blood vessels.
Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
No, mammals have a closed circulatory system
Humans have a closed circulatory system, in which blood is pumped by the heart through dedicated vessels, where it stays contained, as opposed to an open circulatory system (usually found in invertebrates) where blood is pumped out of the heart and vessels.
