Animals that have true coelom are called Eucoelomates such as phylum Annelida, Arthropoda, Mollusca, Echinodermata, Hemichordata and Chordata. The fluid filled body cavity is lined with peritoneum, which is derived by embryonic mesoderm, and separates the digestive tract and outer body cell wall.
Schematic diagrams of the bodies of animals with coeloms, with pseudocoeloms, or without body cavities. In humans all but the cranial cavity develop from the coelom (pronounced SEE-lum). A coelom is a cavity that is entirely enclosed within cells derived from the middle layer of embryonic tissue. A few groups of animals, such as roundworms (Nematoda), have a body cavity that is only partly enclosed by tissue from the middle layer. Such a body cavity is called a pseudocoelom (pronounced SOO-doe-SEE-lum). In a few other groups, such as flatworms (Platyhelminthes), there is no body cavity.
