An incomplete digestive system (found in certain lower invertebrates like Cnidarinas, i.e. hydra, marine jellyfish, and Platyhelminthes, i.e. flatworms) is where a single opening to a pouch-like cavity serves as both mouth and anus. A complete digestive system (all insects have them) means that food processing occurs within a tube-like enclosure, the alimentary canal, running lengthwise through the body from mouth to anus.

What are th two types of digestive system?
The two main types of digestive systems are the complete digestive system and the incomplete digestive system. A complete digestive system features a one-way tract, allowing for the efficient processing of food from ingestion to excretion, as seen in humans and most animals. In contrast, an incomplete digestive system has a single opening for both ingestion and excretion, typical of organisms like jellyfish and flatworms. These systems reflect different evolutionary adaptations to nutrient processing and absorption.
