By the time food leaves the mouth and is pushed down into the gullet (or esophagus), it has already received a sampling of all the kinds of punishment and prodding that will be provided by the 30-foot tube that lies ahead of it.

Which end forms first in ontogeny is a criterion used to classify animals into protostome and deuterostome.
