What is short gut?

Why is a complete gut more efficient than a gastrovascular cavity?

A complete gut allows for unidirectional movement of food through specialized regions like the stomach and intestines, aiding in digestion and absorption of nutrients more efficiently. In comparison, a gastrovascular cavity has a single opening for both ingestion and excretion, limiting the ability to digest food as thoroughly. This makes a complete gut more efficient for nutrient acquisition and waste removal in more complex organisms.


Do arthropods have through gut?
