An Open circulatory system is one in which the flow of blood/hemolymph is from the heart to the peripheral organs then to the body cavity. There is no system of veins to carry the blood back to the heart. This is the arrangement in mollusca.

an open circulatory system
Yes, most arthropods have an open circulatory system, which means that their blood, called hemolymph, directly bathes their tissues. This system is less efficient at transporting oxygen compared to closed circulatory systems found in vertebrates.
In an open circulatory system, the blood does not flow in closed vessels and surrounds the organs directly within the body cavity. This type of circulatory system is found in invertebrates like insects and mollusks.
Bivalves have an open circulatory system, where blood flows freely within the body cavity instead of through a closed network of vessels. Oxygen and nutrients are distributed to the tissues as the blood bathes them directly.
Praying mantises have an open circulatory system. This means that their blood flows freely within the body cavity, rather than being contained within blood vessels.
