They have complete digestive system.
well first of all, DOES not do, and no they have a complete digestive system, which mean they have both a mouth and anus that are seperate
An incomplete digestive system (found in certain lower invertebrates like Cnidarinas, i.e. hydra, marine jellyfish, and Platyhelminthes, i.e. flatworms) is where a single opening to a pouch-like cavity serves as both mouth and anus. A complete digestive system (all insects have them) means that food processing occurs within a tube-like enclosure, the alimentary canal, running lengthwise through the body from mouth to anus.
A digestive system with only one opening is called an incomplete digestive tract. Organisms with this type of digestive system ingest food and eject waste through their mouth.
Humans have a complete digestive system. Incomplete Digestive System: one opening that takes in food and expels waste Complete Digestive System: two openings and a food tube to make sure there is no mixing of food and wastes.
incomplete= cniderians and platyhelminthes complete = every other metazoan. e.g. nematoda, mammals, etc

The digestive system ends when the small intenstine leads to the anus, aka your but hole.
