The mouth, also known as the '''buccal cavity''' or the '''oral cavity''', is the orifice through which an Organism takes in Food and Water . LOCATION In all mammals, the mouth is forward-facing in the Face . Non-mammals have mouths in other locations (e.g. the mouth of the Planarium is in the middle of its abdomen). Some animals, such as the Cnidarians , the Brachiopod s, and the planaria, do not have a separate anus, and thus expel waste through the mouth. ANATOMY Most animals have a complete Digestive System , with a mouth at one end and an anus at the other. Which end forms first in Ontogeny is a criterion used to classify animals into Protostome and Deuterostome . USES Generally the mouth is used to intake food, though it has other uses.
