Body cavity between the body wall and internal organs is called ______________

Answer 1

• The body cavity between the body and internal organs is called coelom.
• A coelom is a cavity that is entirely enclosed within cells derived from the middle layer of embryonic tissue.
• A few groupsof 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.
• In a few other groups, such as flatworms (Platyhelminthes), there is no body cavity.
