(D) An open circulatory system is a type of circulatory system where the blood is pumped out of the heart into body cavities called sinuses,where the tissues are bathed in blood. This type of system is characteristic of most Arthropods (such as insects,spiders,and crustaceans) and most Molluscs (such as snails and clams,excluding cephalopods like squids and octopuses).
