Answer :

Coelem -

• It is the cavity lined by mesoderm.
• It is seen between body wall and gut wall.
• It separates muscles of gut and body wall.
• It helps in the accomodation of visceral organs.
• The coelomic fluid reduces friction between visceral organs.
• It acts as shock absorber.
• Accordingly there are three types -

1. Coelomate
2. Aceolomate
3. Pseudocoelomate

• Aceolomate - There is no body cavity. The space between body wall and digestive cavity is filled with matrix. Ex - Porifera.

• Pseudocoelomate - The body cavity is lined by mesoderm and the mesoderm is in the form of scattered pouches. Ex - Aschelminthes.

• Ceolomate - The ceolom arises from mesoderm and is lined by peritoneal layer filled with ceolomic fluid. Ex - Annelida.
