- mouth - surrounded by strong lips used to grasp and ingest food particles
- pharynx - food is lubricated by mucus secretions
- esophagus - calcium carbonate is added to the food and mucus secretions to neutralize acids
- crop - temporary storage location
- gizzard - digestive process begins as glands excrete enzymes, breaking down the organic material
- intestine - bacteria complete the digestion of organic material
- anus - undigested organic matter leaves the worm
