Nasopharynx lined by ciliated pseudostratified epithelia, oropharynx and laryngopharynx lined by non keratinized epithelium. Mouth serves as an alternate route for air when nasal chambers are blocked. Foramen by which pharynx opens into larynx called glottis. In general it remains open. During swallowing it is closed. It provides passage for air. Pharyns leads into the oesophagus through an aperture called gullet. In general condition it remains closed and opens at the time of swallowing.

The pharynx is a muscular tube that connects the nasal cavity to the larynx and esophagus. It is a common pathway for both food and air. The larynx, also known as the voice box, is located at the top of the trachea and is responsible for producing sound.
The aperture through which the pharynx opens into the larynx is called the glottis. It is a slit-like opening that is surrounded by the vocal cords. During breathing, the glottis is open to allow air to pass through the larynx and into the trachea. During swallowing, the glottis closes to prevent food and liquid from entering the trachea and lungs. The epiglottis, a flap of tissue located at the base of the tongue, helps to direct food and liquid into the esophagus and away from the trachea.
In summary, the pharynx connects the nasal cavity to the larynx and esophagus, and the glottis is the aperture through which the pharynx opens into the larynx. The glottis is surrounded by the vocal cords and is responsible for regulating the flow of air into and out of the lungs.
