Mouth

Wikipedia, the free encyclopedia - Cite This Source

The mouth, also known as the buccal cavity or the oral cavity, is the orifice through which an organism takes in food and water.

Anatomy

All 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.

Mouth cavity

The first space of the mouth is the mouth cavity, bounded laterally and in front by the alveolar arches (containing the teeth), and posteriorily by the isthmus of the fauces.
