In some animals such as worms the coelom acts as a skeleton.

In a pseudocoelom the mesoderm _ the coelom but may line the body wall. The coelom also allows the internal organs to move and grow independently of the outer layer of the body wall. In a _ there is space between the body wall and digestive tract arises within the mesoderm and is termed a _ Eucoelomate. A coelom is a fully-encased fluid-filled body cavity gut lined with mesodermic tissue.

It forms from the three germinal layers during the embryonic development. The lateral mesoderm beyond the somites and nephrotomes splits into two layers.
