Humans have a complete digestive system.
Incomplete Digestive System: one opening that takes in food and expels waste
Complete Digestive System: two openings and a food tube to make sure there is no mixing of food and wastes.

They have complete 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.
well first of all, DOES not do, and no they have a complete digestive system, which mean they have both a mouth and anus that are seperate
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.
A digestive system with only one opening is called an incomplete digestive tract. Organisms with this type of digestive system ingest food and eject waste through their mouth.
incomplete= cniderians and platyhelminthes complete = every other metazoan. e.g. nematoda, mammals, etc
i think a hydra has a incomplete digestive system called the-gastrovascular system
An incomplete gut only has 1 opening. Basically if something has an incomplete gut, it has no anus, and all food that it takes in must either be completely digested, or re-excreted through the mouth.
A jellyfish has an incomplete digestive system. It has a single opening that serves as both the mouth and anus, allowing food to enter and waste to exit through the same orifice. This means there is no separate anus, and digestion occurs in a central cavity called the gastrovascular cavity.
bcz our digestive system the food will not be digested
