Best Answer: The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart. There are five pairs of aortic arches, which have the responsibility of pumping blood into the dorsal and ventral blood vessels. The dorsal blood vessels are responsible for carrying blood to the front of the earthwormâs body.
This section is about Structures of the Heart. An auricle is a feature of the anatomy of the heart. There are two auricles in the heart. One auricle is attached to each of the anterior surfaces of the outer-walls of the atria (that is, the left atrium and the right atrium). Visually, they look like wrinkled pouch-like structures. Their purpose is to increase the capacity of the atrium, and so also increase the volume of blood that it is able to contain.
