The dorsal blood vessel and ventral blood vessel along with the aortic arches supply blood to the organs in earthworms.
Explanation:
The aortic arches function like a human heart. There are five pairs of aortic arches, which are responsible for pumping blood into the dorsal and ventral blood vessels.
The dorsal blood vessels carry blood to the front of the earthworm's body whereas the ventral blood vessels are responsible for carrying blood to the rear of the earthworm's body.
The earthworm has a dual circulatory system in which both the coelomic fluid and a closed circulatory system carry the food, waste and respiratory gases. The blood consists of amoebic cells and haemoglobin dissolved in plasma.
