The earthorm has a closed circulatory system with five main blood vessels:
- Dorsal (above the digestive tract) - it moves blood forward
- Ventral (beneath the digestive tract)
- Subneural Vessel (below the nerve cord)
- Right & Left Lateroneural vessels (either side of nerve cord)

What is the function of the blood vessels on the outer wall of the heart?
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
Do earthworms have lungs?
The moist skin of earthworms is used for gas exchange. Furthermore, their closed circulatory systems contain blood vessels close to the skin which allow for the exchange of O2/CO2. Reference = Biology 191 laboratory manual
Why is earthworm blood red?
Earthworms have blood and it is enclosed in a network of tubes much like the blood system of mammals. It is red because it contains the oxygen carrying pigment hemoglobin. Unlike mammals, where the hemoglobin is inside red blood cells, earthworm hemoglobin is just mixed in the liquid of the blood, commonly called hemolymph. Earthworms pump their blood around the body with the help of 5 specialized blood vessels that contract and expand. They are the worm's hearts.

How do earthworms benefit from a closed circulatory system?
Earthworms have a closed circulatory system, meaning that they contain blood in different blood vessels; the Arteries which are a form of blood vessels that carry blood away from the heart, the veins which are blood vessels that carry blood toward the heart, and the capillaries which are tiny blood vessels between arteries and veins that distribute oxygen-rich blood to the body, a animal is classified as a closed circulatory because all of these vessels are pumped via its heart beats which is then pushed throughout its body by contractions callled 'Peristalsis'
