In the open circulation, the blood is not enclosed in the blood vessels and is pumped into a cavity called hemocoel.

Open circulatory systems are systems where blood, rather than being sealed tight in arteries and veins, suffuses the body and may be directly open to the environment at places such as the digestive tract. Open circulatory systems use hemolymph instead of blood
