The soft palate and uvula move to close off the nasopharynx during swallowing. This prevents food and liquids from entering the nasal cavity and ensures that they are directed into the esophagus towards the stomach.
Uvula flips upward during swallowing, reducing the chance of fluids entering the nasopharynx.

What is the name of the structure that prevents fluid from entering the nasopharynx during swallowing?
The soft palate, specifically the uvula, helps prevent fluid from entering the nasopharynx during swallowing by closing off the opening between the nasal cavity and the throat.
Why is it important that the nasopharynx gets closed off by the uvula during swallowing?
Closing off the nasopharynx during swallowing is important to prevent food and liquid from entering the nasal cavity and causing aspiration, which can lead to respiratory issues and infections. The uvula helps to seal off the nasopharynx to ensure that food and liquid travel down the esophagus instead of the airway.
The larynx is covered by what during swallowing?
During swallowing, the larynx is covered by the epiglottis. The epiglottis is a flap of cartilage that closes off the top of the larynx to prevent food and drink from entering the airway. This action helps to direct food and liquids into the esophagus and away from the lungs.
Why food and air are not usually mixed during swallowing?
Food and air enter the body through separate pathways - food into the esophagus and air into the trachea. During swallowing, the epiglottis closes over the trachea to prevent food from entering the airway. This reflex ensures that food goes to the stomach and air goes to the lungs, reducing the risk of choking.
What is the leaf-like cartilage after the esophagus?
The leaf-like cartilage after the esophagus is the epiglottis. It is a flap of tissue that closes over the trachea during swallowing to prevent food from entering the airway.

Does the soft palate rises reflexively to open the nasopharynx when you swallow food?
Yes, the soft palate rises reflexively to close off the nasopharynx during swallowing. This helps prevent food or liquid from entering the nasal cavity during the swallowing process.
Closes over the glottis during swallowing?
Epiglottis
What closes and seals the lower airway during swallowing?
epiglottis
What structure closes over the trachea to protect it during swallowing?
The epiglottis.
What is the apparatus that closes during swallowing to prevent food from entering the trachea?
The epiglottis is the flap of cartilage in the throat that closes during swallowing to cover the opening of the trachea, preventing food or liquid from entering the airway. This helps direct food to the esophagus for safe passage to the stomach.
What is the involuntary reflex during swallowing?
the tongue rolling the bolus into the pharynx
What happenes to jaws and larynx during breathing and swallowing in fish?
The jaws and larynx during breathing and swallowing in fish, contracts. The jaws suck in, and the larynx contracts and closes temporarily while the breath is happening.
Between the trachea and the esophogus is a flap of tissue that closes when you swallow what is it and its function?
Is to close the laryngeal inlet during swallowing
What is the flap the closes off the larynx and prevents food and water from entering the larynx during swallowing?
It's called the 'epiglottis'.
What region of the pharynx closest to the larynx?
The laryngopharynx is the region of the pharynx that is closest to the larynx. It is located below the oropharynx and is responsible for directing air and food into the proper passages during swallowing.
