Difference between complete and incomplete digestive system
What is the basic difference between a complete and an incomplete digestive system? How are such kinds of digestive tubes related or not to extracellular digestion?
Expert
Animals with an incomplete digestive system are such in which the digestive tube consists only one opening (that is, cnidarians and platyhelminthes). The animals with a complete digestive system are such in which the digestive tube consists of two openings, anus and mouth (all other animal phyla, with the exception of poriferans, which do not encompass any digestive tube).
In animals with incomplete digestive tubes, the digestion is mixed; it starts in the extracellular space and completes in the intracellular space. In animals with complete digestive systems extracellular digestion in the digestive tube predominates.
