As you can see in the earthworm diagram, from front to back, the basic shape of the earthworm is a cylindrical tube, divided into a series of segments that compartmentalize the body. Grooves called “furrows” are generally, externally visible on the body demarking the segments; dorsal pores and nephridiopores exude a fluid that moistens and protects the worm’s surface, allowing it to breathe. The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm’s mouth where it is swallowed by the pharynx.

The earthworm has a closed circulatory system. 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 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. The earthworm’s nervous system has three parts: the central nervous system, peripheral nervous system, and sympathetic nervous system. You can observe the systems in the following diagrams.
