Pharynx
The pharynx is the part of the throat behind the mouth and nasal cavity, and above the esophagus and larynx – the tubes going down to the stomach and the lungs. It is found in vertebrates and invertebrates, though its structure varies across species.

Is epiglottis part of pharynx?
The epiglottis is normally pointed upward during breathing with its underside functioning as part of the pharynx.
What is the relationship between the pharynx the esophagus and the epiglottis?
The epiglottis drops downward to prevent food from entering the larynx and trachea in order to direct the food into the esophagus. Peristaltic movements propel the food from the pharynx into the esophagus.
Is pharynx and epiglottis same?
The pharynx carries food and air to the esophagus and larynx respectively. The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system.
What comes first pharynx or epiglottis?
The oral pharynx begins at the back of the mouth cavity and continues down the throat to the epiglottis, a flap of tissue that covers the air passage to the lungs and that channels food to the esophagus.
What is the difference between the pharynx and the esophagus?
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 function of the epiglottis?
The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe.
What is the pharynx also known as?
Pharynx (Throat) The pharynx, usually called the throat, is part of the respiratory system and digestive system. It carries air, food and fluid down from the nose and mouth. The pharynx is the site of common illnesses, including sore throat and tonsillitis.
What is the difference between larynx and epiglottis?
The larynx is the upper opening into the windpipe (trachea), the passageway to the lungs. Epiglottis — a flap of soft tissue and cartilage located just above the vocal cords. The epiglottis folds down over the vocal cords to help prevent food and irritants from entering the lungs.
What are the 3 parts of pharynx?
The pharynx is divided into three regions according to location: the nasopharynx, the oropharynx, and the laryngopharynx (hypopharynx). The nasopharynx is the portion of the pharynx that is posterior to the nasal cavity and extends inferiorly to the uvula.
When swallowing the epiglottis prevents food from entering the larynx?
When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They also tightly close during swallowing. That prevents food from entering your lungs.
Where does the pharynx begin and end?
The pharynx is a muscular column that begins in the head posterior to the nasal cavity, travels inferiorly behind the oral cavity before finally merging with the larynx and esophagus.
What is the difference between pharynx and larynx?
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 oral and the nasal cavities open into the pharynx.
Which portion of the pharynx connects with the esophagus?
laryngopharynxThe laryngopharynx or hypopharynx is the caudal part of the pharynx; it is the part of the throat that connects to the esophagus and trachea. It lies inferior to the epiglottis and marks the division between the respiratory and digestive system pathways.
Is the pharynx part of the esophagus?
The pharynx is a hollow tube that starts behind the nose, goes down the neck, and ends at the top of the trachea and esophagus. The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.
Does the pharynx come before the esophagus?
The pharynx, commonly called the throat, is a muscular, funnel-shaped passageway inside the body. It connects the mouth and nose to the esophagus (leading to the stomach) and larynx (leading to the trachea and then lungs).
Which of the following is the correct order of organs by which food passes?
The organs that make up your GI tract, in the order that they are connected, include your mouth, esophagus, stomach, small intestine, large intestine and anus.
What is the difference between a swallowing glottis and an epiglottis?
While swallowing glottis moves upward. While swallowing epiglottis moves downwards. Glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis is a cartilaginous flap on top of the glottis that prevents the food from entering into the larynx. The main difference between glottis and epiglottis is their ...
What is the role of vocal cords in swallowing?
Epiglottis, a leaf-shaped cartilaginous flap, prevents the food to enter the airway passage of the respiratory system while swallowing. While swallowing the larynx muscles contract and cause upward movement of the glottis and downward movement of the epiglottis. In this article, we look at the various ...
