Roundworm-Ascaris Lumbricoides 

The digestive system of a roundworm is just like most other worms within its phylum. It latches onto its prey, and gets food from the mouth. The food moves through the pharynx into the intestine, where it is again released through pores. The food mainly goes through the reproductive pore, excretory pore, and the  psuedocoleom. These pores help the roundworm function properly, reproduce, and prevent the roundworm from starving respectively.
