A coelom is a fluid filled cavity within the mesoderm, it can be seen as the digestive track of an earthworm. Coelomic fluids assist in locomotion and regulation of fluid transfer through the body wall. It can also serve as a temporary food storage, excretion of nitrogen-containing wastes and for maturation of gametes.

The function of an earthworm's nephridium is to excrete wastes from the earthworm's body.
No,it has a hydrostatic skeleton.It emerges due to pressure caused by fluids in the coelom.
The structures of a flatworm and a earthworm are different by the way the are shaped. The earthworm is the one that looks like a regular worm it is more rounded and a flatworm looks like leeches.
it acts as a heart for an earthworm.... <3
the brain is essential for the movement of the earthworm. If the brain of the earthworm is removed, the earthworm will move continuously without stop
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
The coelom of an earthworm is its body cavity. There are three categories for grouping animals according to their coeloms: coelomate (animals that have a true coelom lined by muscle tissue on both sides), pseudocoelomate (animals that have a coelom line by muscle tissue only on one side), and acoelomates (animals that do not have a body cavity lined by muscle tissue on either side). Earthworms are coelomate animals.
As protostome phyla evolve, the coelom may change in structure and function. For example, in some phyla like annelids, the coelom functions as a hydrostatic skeleton. In arthropods, the coelom may be reduced or lost altogether.

The blood circulatory system of the earthworm consists of five main blood vessels; it has aortic arches instead of a heart. The coelom also circulates food, so it could be considered a digestive system or a circulatory system.
