In an open circulatory system, a tubular heart pumps hemolymph into a hemocoel (a system of interconnected sinuses), where chemical exchange can occur with the "bathed" tissues. The hemolymph diffuses back to the heart. This creates a sluggish blood flow because of low pressure & low oxygen content, resulting in low efficiency.
In a closed circulatory system, a muscular heart pumps blood into large vessels that branch into smaller vessels that course through the organs. The blood is confined to vessels and are distinct from the interstitial fluid.
Basically, an open circulatory system is somehow connected to the environment, while the closed circulatory system is just confined in the animal's body.

Grasshoppers have an open circulatory system, and worms have a closed circulatory system. There you go. :)
Do amphibians have an open circulatory system or a closed circulatory system?
Amphibians have closed circulatory system Closed
What is the difference between a closed and open circulatory system?
We, as vertebrates, have a closed system in that our blood travels from the heart and back. Other organisms don't have such a system. Open circulatory systems allow all fluids in an organism to mix.

What is the difference between a human circulatory system and chimpanzee circulatory system?

Do platypuses have an open or closed circulatory system?
Platypuses have a closed circulatory system.
What is the circulatory system in the body?
closed circulatory system.
What is the difference between an open open and closed circulatory system?
Closed circulatory systems have blood that does not flow in defined blood vessels. Examples are insects and how their organs are bathed continually in "blood". Open circulatory systems have blood that flows in vessels. Humans have this system as blood flows in veins, arteries and capillaries.
