Do Earthworms Have A Closed Or Open Circulatory System

There are three main vessels that supply the blood to organs within the earthworm. The cephalopod group includes the living octopuses squid cuttlefish and nautiloids. All annelids are segmentedAnnelids have a well-developed closed circulatory system one in which blood is limited to vessels that is segmentally arranged. They have a closed circulatory system but they dont have a true heart. These vessels are the aortic arches dorsal blood vessels and ventral blood vessels. They also have a complete one-way digestive tract with a mouth and anus. An earthworm circulates blood exclusively through vessels.

This system in the presence of vessels conducts blood throughout the body.

If you are wondering what type of circulatory system an earthworm has it is important to first understand that there are two main types of circulatory systems. Is the system that is found in vertebrates and a few invertebrates like earthworms. An earthworm circulates blood exclusively through vessels. Such sophisticated circulatory system is only observed in vertebrates with a 4-chambered heart mammals birds and crocodiles. They have a closed circulatory system but they dont have a true heart. They have three blood vessels dorsal vessel pumps blood forward while the other 4 pump blood to the rear.
