Animals having an incomplete digestive system are those in which digestive tube has only one opening (platyhelminthes, cnidarians). Animals having a complete digestive system are those in which digestive tube has two openings, mouth and anus (all other animal phyla, having the exception of poriferans, which are not having any digestive tube).In animals which are having incomplete digestive tubes, digestion is mixed, it has started in the extracellular space and finishes in intracellular space. With animals having complete digestive systems extracellular digestion within digestive tube predominates.
