"They are neither. This is because they do not have a true gut. Protostomes are annelidids(earthworms) Mollusca(clams, snails, octopus, etc.) and arthropods which are your insects or spiders. The only Deuterostomes are Phlya Chordota and Echinodermata." The above answer is incorrect. Plathyhelminthes are protostomes. There are many, MANY groups of protostomes besides annelids, molluscs, and arthropods.

fibre helps the feces to form bolus. Fibre is not at all digested in the gut. It moves all the way through the gut sticking to the feces and makes it bolus for easy passage.
The gut is where food is digested, nutrients are absorbed into the bloodstream, and indigestible waste moves through and leaves the body.

Nutrients leave the gut and enter the bloodstream through the lining of the small intestine.
Terrestrial arthropods excrete metabolic wastes in the form of uric acid, which is solid and fairly dry. Aquatic arthropods excrete ammonia through gills or other membranes.
