Answer. There is no as such digestive system in porifera. But they have unique pores known as ostia through which water is drawn into osculum where many cell takes up the food from water and also exchange gases the flow of water is in only one direction due to presence of cilia.
In cnidarian there is only one way digestion means mouth and anus is same that means it get food from mouth an excrete from same portion. So it have some specific place for entry of food. It also have gastrovascular cavity.
In platyhelminthes there is one way as in cnidaria. It also do have gastrovasculae cavity . The Body of platyhelminthes is divided into parts.

The digestive system plays a critical role in how our body takes in and processes food. Organs of the digestive system are usually referred to as "your gut". It's also the beginning of the process in which our body receives nourishment. Understanding this process can be helpful when communicating with patients or when analyzing charts for assigning the correct medical codes. If you had to explain the point at which the digestive process actually begins and one related disease or...
