The earthorm has a closed circulatory system with five main blood vessels:Dorsal (above the digestive tract) - it moves blood forwardThe remaining four all move the blood to the rear of the earthworm: Ventral (beneath the digestive tract)Subneural Vessel (below the nerve cord)Right & Left Lateroneural vessels (either side of nerve cord)
Blood moves through the ventral blood vessel to the posterior of the body and through the dorsal vessel to the anterior of the body. The dorsal blood vessel contracts to push the blood back and then forward to the ventral vessel where a series of aortic arches act as hearts to move blood forward to the anterior end and through the capillaries.
