The digestive chamber has two openings, a mouth and an anus, and while in the Nephrozoa There exists an inner physique cavity, a coelom or pseudocoelom.
The mobile wall is usually lacking. As a result, an animal mobile in a very hypotonic Resolution will swell and ultimately burst (lyse) as it lacks the mobile wall that forestalls lysis throughout abnormal osmosis.
