Explain the digestion of food by star fish ?

Starfish have a complete digestive system with a mouth at the centre of their underside and an anus on their upper surface. Food brought into the cardiac stomach through the mouth where digestion of food takes place. The cardiac stomach is connected to a pyloric stomach (located above it), which in turn is connected to both the anus and to the pyloric ducts and pyloric cecum which extend out into each arm  The pyloric ceca are digestive glands. Digested material is absorbed through the pyloric ceca for transport to the rest of the body. Starfish digest food through their stomach: the cardiac and pyloric.
