yes, I think it's called coelom. An organism with a true body cavity is called a eucoelomate. This means that the body cavity exists between the inner layer of mesoderm and the outer layer of mesoderm. A pseudocelomate kind of has a body cavity but it is the space between the endoderm and mesoderm. This is not a true body cavity because it is not mesoderm on mesoderm.
false.
The kidneys are located in the peritoneal cavity. Infection of this cavity is called peritonitis, and can be deadly. Dialysis can be done by instilling dianeal solution into the peritoneal cavity, and allowing the semipermiable membranes surronding the kidneys, and other organs to "clean themselves." This process is called peritoneal dialysis.
The body has three tissue layers and a fluid-filled false body cavity, meaning the cavity is between the inner and middle layers rather than the middle layer and the outer layer, as it is in complex animals.
Animals that have three layers of embryonic tissue with organs in a cavity completely lined with the mesoderm are called triploblastic animals.
Yes. A coelem is a fluid-filled body cavity completely lined by a layer of mesoderm cells.
they are coelomates, which means that their body cavity is fully lined with the mesoderm.

the body cavity between the digestive system and the body wall is completely lined by tissue derived from mesoderm.

Coelom is a greek work literally meaning body cavity.A body cavity is a space between the alimentary canal and body wall. When it is lined by a layer of mesoderm, then it is called a true coelom. Depending upon this the animals are classified intoAcoelomates - Animals which don't have body cavity. Eg: PlatyhelminthesPseudocoelomates - Animals in which the body cavity is formed from embryonic blastocoel. This blastocoel acts as a body cavity in adults. Eg: AschelminthesSchizocoelomates - Animals in which the body cavity formed by splitting of mesoderm. Eg: Annelida, Arthropoda and MolluscaEnterocoelomates - Animals in which body cavity is derived from entero-mesoderm. Eg: Echinodermata, Hemichordata and chordata.
A bilateral animal has a lined gut cavity. On the other hand, animals like roundworms have a gut cavity but it is only partially lined.
false.
The coelom is a fluid-filled body cavity between the intestines and the body wall of some higher metazoans. It is lined with a mesodermal epithelium. The coelom is formed within the mesoderm of the embryo.
Earthworms are Coelomates. They posses a true coelom, which is a body cavity that is completely lined by tissue derived from the mesoderm. This body cavity can either be empty air-filled space separating the digestive tract from the outer body wall, or fluid-filled space. Since triploblastic animals are defined as animals having three germ layers, earthworms is considered a triploblastic animal for it possess a endoderm, a mesoderm, and a ectoderm.
Animals that have lined abdominal cavities are known as coelomates. The coelom, or body cavity, is used for protecting their internal organs.
