How do earthworms benefit from a closed circulatory system?

Answer 1

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'

Answer 2

An earthworm has a closed circulatory system. Its blood circulates through its vessels. These vessels include the aortic arches, dorsal blood vessels, and the ventral blood vessels.

Answer 3

In a closed circulatory system, less blood is required to reach all parts of the body.
