What is the Segmented digestive system?
A segmented digestive system is a type of digestive structure found in certain animals, particularly those with a more complex body organization, such as annelids and some arthropods. It consists of specialized sections or segments, each performing distinct functions in the digestion and absorption of nutrients. This allows for more efficient processing of food as it moves through different regions, enabling the breakdown of complex materials and the absorption of nutrients to occur in a systematic manner. In contrast to simpler digestive systems, segmented systems facilitate greater specialization and efficiency in nutrient processing.

Is tape worms segmented worms?
Yes. However, this is not a true coelom. Roundworms are pseudocoelomates -- their mesoderm lines the endoderm and ectoderm, but there is no connection between the two. Therefore, it does not satisfy the definition of a coelom. However, since there is a body cavity still, this animal is said to be a pseudocoelomate.
