How is a flatworm tegument different from a roundworm cuticle?
In flatworms (Platyhelminthes), they have a tegument which is a living outer layer. As a parasite living in the gut of the host, it wants to absorb nutrients from the medium around them, therefore it is important that they have a metabolically active outer layer for vital activities such as absorbtion, protection and secretion. On the other hand, roundworms (Nemathelminthes) have a rigid outer cuticle which works with the muscles to create a hydroskeleton. It has a digestive system which starts with a mouth and ends at the anus. This is significant from a medical point of view as this characteristic, having a cuticle or tegument determines what kind of drug is used to treat the parasite. Some drugs can destroy the living outer layer of a tapeworm, while other drugs are ingested by the roundworms which then attacks the lining of their gut.

How does a fluke protect itself from the digestive enzymes of its hosts?
Flukes have a protective covering called a tegument that helps them evade the digestive enzymes of their hosts. The tegument acts as a barrier, preventing the enzymes from reaching the fluke's body. Additionally, some flukes have evolved mechanisms to neutralize or resist the effects of digestive enzymes.
