The Pharynx
The pharynx is that part of the digestive tube which is placed behind the nasal cavities, mouth, and larynx.

pharynx -- Cavity in the digestive tract just past the mouth itself. May be muscularized for sucking or swallowing in various animals.
phloem -- Nutrient-conducting tissue of vascular plants.

pharynx
(fah-rinks)
An area in the vertebrate throat where air and food passages cross; in flatworms, the muscular tube that protrudes from the ventral side of the worm and ends in the mouth.

pharynx The passageway between the mouth and the esophagus and trachea. Food passes from the pharynx to the esophagus, and air passes from the pharynx to the trachea.

The Mouth and Pharynx
Mechanical breakdown begins in the mouth by chewing (teeth) and actions of the tongue. Chemical breakdown of starch by production of salivary amylase from the salivary glands.

In the fishes these structures form the gill slits through which water moves from the pharynx, over the gills and out of the body. Sometimes human babies are born with left over small pits in the neck area.

It is marked by inflammation of the nasal mucosa, the pharynx and conjunctiva and by headache and severe, often generalised myalgia. Fever, chills and prostration are common.

Your mouth and pharynx are both used to swallow and to breathe. There is a branching point where you will find the epiglottis that directs food to your stomach and air to your lungs.

pathway by which food enters the body and solid wastes are expelled. The alimentary canal includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and anus. See digestion.

Spratt (University of Sussex, U.K.), both inter- and intraspecies recombination can occur in bacteria, particularly when the bacteria coexist in an environment such as the nasopharynx.

[Gr. thyreoeides - sheild form]. An endocrine gland in the throat region which is responsible for controlling metabolism and growth. It is formed from a ventral diverticulum of the endoderm of the pharynx at the level of the second pharyngeal arch.

nematode has been used in research since the mid-1960's and is important in the study of cell differentiation. An adult worm is about 1mm in length and feeds on bacteria. The pulsating structure seen in this video clip is the very active pharynx.
