What does a worms mouth do?
Worms (excepting the flatworms) are the simplest animals to have a one-way digestive tract (that is, they do not expel waste from the same hole that they eat through). Originally, the animals for whom it is taxonomically correct to call worms were all classified under the single phylum Vermes; later, they were split into three separate phyla: Platyhelminthes (planarians, or flatworms, this being the simplest of the three worm phyla) Nematoda (nematodes, or roundworms) and Annelida(annelids, or segmented worms such as earthworms and leeches; this is the most physiologically complex of the three worm phyla); over time, several new phyla have been developed.Worms are so separately classified partially because their eating habits and oral anatomy are so diverse. Many, such as earthworms, are decomposers (dirt and debris eaters); earthworms suck food into their bodies and push it down along the body using peristaltic muscular contractions. Other worms, such as leeches and many varieties or roundworm and flatworm, are parasitic. Some species of leeches can bite humans, latching on with their suckers and secreting anticoagulant to keep the blood flowing into the gullet. Roundworms have a digestive system lined with hard cuticle and often ridges; some species (the carnivorous ones) have teeth; others have a stylet that they can poke into other organisms to suck fluids out.Unlike roundworms and annelids, flatworms do not have a mouth; they absorb nutrients through their skin. However, flatworms are the simplest animals to have a specialized digestive and excretory system.
