Function
It is part of the digestive system and respiratory system of many organisms. For the Physics term GUT, please refer to Grand unification theory The gastrointestinal or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and...
The Respiratory System Among four-legged animals, the respiratory system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. ...
Because both food and air pass through the pharynx, a flap of connective tissue called the epiglottis closes over the trachea when food is swallowed to prevent choking or aspiration. In humans the pharynx is important in vocalization. Layers of Atmosphere - not to scale (NOAA)[2] Earths atmosphere is a layer of gases surrounding the planet Earth and retained by the Earths gravity. ...

Parts The human pharynx is conventionally divided into three sections:
Nasopharynx The nasopharynx lies behind the nasal cavity. The pharynx is the part of the digestive system of many animals immediately behind the mouth and in front of the esophagus. ...

The soft palate, or velum, is the soft tissue comprising the back of the roof of the mouth. ...
The uvula (IPA: ) is a small, mucosa-covered set of muscles, musculus uvulae, hanging down from the soft palate, near the back of the throat. ...
Hypopharynx The hypopharynx, also known as the laryngopharynx roughly corresponds to the levels between C3 to C6, it includes the pharyngo-oesophageal junction (postcricoid area), the piriform sinus, and the posterior pharyngeal wall. In human anatomy, the hypopharynx is the bottom part of the pharynx, and is the part of the throat that connects to the esophagus. ...

Like the oropharynx above it the hypopharynx serves as a passageway for food and air and is lined with a stratified squamous epithelium. H&E stain of biopsy of normal esophagus showing the stratified squamous cell epithelium Section of the human esophagus. ...
It lies directly anterior to the upright epiglottis and extends to the larynx, where the respiratory and digestive pathways diverge.
At that point the laryngopharynx is continuous with the esophagus posteriorly. The esophagus conducts food and fluids to the stomach; air enters the larynx anteriorly. During swallowing, food has the "right of way", and air passage temporarily stops. In anatomy, the stomach is a bean-shaped hollow muscular organ of the gastrointestinal tract involved in the second phase of digestion, following mastication. ...
