In animal anatomy, the mouth is the first portion of the alimentary canal that receives food.
Some animal phyla, including vertebrates, 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. The first space of the mouth is the mouth cavity, bounded laterally and in front by the alveolar arches (containing the teeth), and posteriorly by the isthmus of the fauces.

Famous quotes containing the word mouth:
“Folks don’t like to have somebody around knowin’ more than they do. It aggravates ‘em. You’re not gonna change any of them by talkin’ right, they’ve got to want to learn themselves, and when they don’t want to learn there’s nothing you can do but keep your mouth shut or talk their language.”
—Harper Lee (b. 1926)
“The speaker in this case
is a middle-aged witch, me
tangled on my two great arms,
my face in a book
and my mouth wide,
ready to tell you a story or two.”
—Anne Sexton (1928–1974)
“What wondrous life in this I lead!
Ripe apples drop about my head;
The luscious clusters of the vine
Upon my mouth do crush their wine;
The nectarine and curious peach
Into my hands themselves do reach;
Stumbling on melons, as I pass,
Ensnared with flowers, I fall on grass.”
—Andrew Marvell (1621–1678)
