The food is passed through the digestive tract when the worm moves. The movement causes the muscles to contract and move the food through the system.
Several ways. It can be passed through the digestive tract and imerge as urine or manure or through the skin by sweat.
Fiber is the nutrient that helps move food through the digestive tract. It provides bulk, which activates the stretch receptors in the muscles of the digestive tract, stimulating them to activity.

Grasshoppers eliminate their nitrogenous waste through the malipighian tubules that are on the digestive tract. Earthworms eliminate their nitrogenous waste by the nephridia.
The phylum Annelida includes worms that have a true coelom and a complete digestive tract. Annelids, such as earthworms and marine bristle worms, exhibit segmentation and are known for their well-developed body cavities and digestive systems.
The definition of absorption in the digestive tract is is the process by which nutrient molecules pass through the wall of your digestive system onto your blood
Peristalsis is the process that propels food through the digestive tract. It involves rhythmic contractions of the muscles in the gastrointestinal tract that push food and nutrients along the digestive system.
The movement of food through the digestive tract is regulated by muscles. Muscles produce a narrowing which pushes the food through each of the digestive organs until it reaches the entrance of the stomach.

Leeches have a complete digestive tract. Leeches are members of Phylum Annelida. This phylum has the general characteristic of having a complete digestive tract, i.e. food goes in through the mouth, pass through digestive tract of some sort like stomach and/or intestine, waste gets discarded through some sort of rectal opening, i.e. anus. In comparison, an incomplete digestive tract generally means food goes in and waste come out of the same opening, i.e. mouth=anus. Lower level invertebrates have incomplete digestive tract like Phylum Cnidaria and Phylum Platyhelminthes members.
