Serves as a portal for expelling solid waste.
There is one opening that serves as both mouth and anus
The anus is the exit point of the digestive system where waste (feces) is expelled from the body. It does not play a role in digestion, as the digestion process primarily occurs in the stomach and intestines. The anus's main function is to control the release of waste from the body.

digestion
The anus is not involved in either chemical or mechanical digestion. Its main function is to expel indigestible material out of the body in the form of feces.
Cnidarians, such as jellyfish and sea anemones, have a simple digestive system with a single opening that serves as both mouth and anus, leading to a central gastrovascular cavity where digestion occurs. In contrast, humans possess a more complex digestive system with a separate mouth and anus, involving a long, tubular gastrointestinal tract that facilitates specialized processes for digestion and nutrient absorption. Additionally, cnidarians primarily rely on extracellular digestion in their gastrovascular cavity, while humans utilize both mechanical and chemical digestion throughout their digestive tract.
