In mammals, invertebrates and most fish, the anus (: anuses or ani; from Latin, 'ring' or 'circle') is the external body orifice at the exit end of the digestive tract (bowel), i.e. the opposite end from the mouth. Its function is to facilitate the expulsion of waste that remains after digestion.

AI overview

The anus is the external opening at the end of the digestive tract through which waste material exits the body after digestion. It serves the important function of allowing organisms to eliminate the undigested matter that the body cannot use.
