The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It
serves both the respiratory and digestive systems
by receiving air from the nasal cavity and air, food, and water from the oral cavity.
What are the three functions of the pharynx?
Pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves
both respiratory and digestive functions
. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.
What are the two functions of pharynx?
The pharynx serves
both respiratory and digestive functions
. It is a 5-inch-long cylindrical tube that involves the passage of food and air into its appropriate chambers. The connection between the oral and nasal regions enables us to breathe through nose and mouth.
What are the functions of the pharynx Class 10?
The main functions of the pharynx are:
It makes air warm and humidifies it before reaching the lungs
. It helps in the movement of food to the oesophagus. Circular muscles help in pushing the food down and longitudinal muscles help in swallowing the food by lifting and widening the walls.
What is called pharynx?
The throat
(pharynx) is a muscular tube that runs from the back of your nose down into your neck. It contains three sections: the nasopharynx, oropharynx and laryngopharynx, which is also called the hypopharynx.

What is the main function of the larynx?
The most basic function of the larynx is
to provide sphincteric protection of the lower airway
, most efficiently achieved by simultaneous adduction of both vocal cords. Such action serves to close the glottis by involving the activation of both thyroarytenoid muscles, among other groups of adductors.
How does the pharynx work?
The pharynx, or throat, is the passageway leading from the mouth and nose to the esophagus and larynx. The pharynx
permits the passage of swallowed solids and liquids into the esophagus
, or gullet, and conducts air to and from the trachea, or windpipe, during respiration.
What is the role of pharynx in digestion?
Because of its location, the pharynx helps the respiratory system by allowing air to make its way to the respiratory tract. For digestion, the use of the muscles surrounding the pharynx (both circular constrictive muscles and longitudinal muscles)
work together to send food and drink down to the esophagus
.
What is the role of pharynx in respiration?
The pharynx acts
as a passageway for food on its way to the stomach and for air en route to the lungs
. The mucosal epithelium in the pharynx is thicker than elsewhere in the respiratory tract as it has to protect the tissues from any abrasive and chemical trauma caused by food.
What is pharynx short answer?
The pharynx is
a membrane-lined cavity present behind the nose and the mouth
, connecting them to the larynx and esophagus respectively. The larynx is a muscular organ that forms an air passage for the lungs and vocal cord. It is a part of the respiratory system. … Both food and air pass through the pharynx.
What is the role of larynx class 10th?
The main function of the larynx is
sound production
. It facilitates respiration and also protects the lower respiratory tract. Epiglottis covers the upper part of the larynx and prevents food from entering the larynx and trachea.
What is difference between pharynx and larynx?
The main difference between pharynx and larynx is that
pharynx is a part of an alimentary canal
, which extends from the nasal cavity and mouth to the larynx and the esophagus whereas larynx is the upper portion of the trachea. … The larynx is also called the vocal box since it contains vocal cords.
What are the three parts of the pharynx and their functions?
These parts include the
nasopharynx, oropharynx, and laryngopharynx
. The nasopharynx is the most superior, or uppermost, part of the pharynx that works with the nasal cavity during breathing. It provides a passageway for air moving from the nose.
What is the main job of the pharynx quizlet?
The main function of the pharynx is
to provide a passageway for the respiratory and digestive tracts
. The pharynx is also referred to as the throat. The esophagus seems to have only one important function in the body – to carry food, liquids, and saliva from the mouth to the stomach. You just studied 33 terms!
What is the function of throat?
The throat (pharynx and larynx) is a ring-like muscular tube that
acts as the passageway for air, food and liquid
. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).
