This worm, like most earthworms, has a dual circulatory system in which both the coelomaic fluid and a closed circulatory system carry the food, waste, and respiratory gasses. The cardiovascular system has five main blood vessels:
· The dorsal vessel which runs above the digestive tract
· The ventral vessel, which runs below the digestive tract
· The subneural vessel which runs below the ventral nerve cord
· Two lateroneural vessels on either side of the nerve cord
The dorsal vessel moves the blood forward, while the other four vessels carry the blood to the rear.
