Solution(By Examveda Team)

Earthworm has a circulatory system that is extensive and Closed type.
An earthworm is a terrestrial invertebrate that belongs to the phylum Annelida. They exhibit a tube-within-a-tube body plan, they are externally segmented with corresponding internal segmentation and they usually have setae on all segments.
Earthworms have a dual circulatory system in which both the coelomic fluid and a closed circulatory system carry food, waste and respiratory gases.
The closed circulatory system has five main blood vessels: the dorsal (top) vessel, which runs above the digestive tract, the ventral (bottom) vessel, which runs below the digestive tract; the subneural vessel, which runs below the ventral nerve cord; and two lateroneural vessels on either side of the nerve cord.
