body cavity

the space within the body of most animals in which the gut and various organs are suspended. It normally contains fluid and is derived embryologically in different ways in different groups of animals. Absent in PLATYHELMINTHS and NEMERTINE worms, it is derived from the COELOM in vertebrates and from the HAEMOCOEL in arthropods and molluscs. It occurs as an intercellular space in nematode worms.
