The most important aspect is the closure of the epiglottis to keep material from entering the lungs while directing food past the lung entry to be directed to the esophageal sphincter for entry to the stomach. If the closure of the epiglottis is defective, one will choke on food or fluid and a cough reflex should expell it.
What else can I help you with?
Is swallowing a reflex or instinct?
Swallowing is a reflex.
Is the tongue involved in the swallowing reflex?
The tongue is involved in the swallowing reflex insofar as it raises voluntarily to force food backward toward the pharnyx, where reflex action takes over in which the larynx is closed by the epiglottis and the nasal passages are closed by the soft palate so that food does not enter into the trachea. Food then moves down the esophagus by peristalsis and gravity.
Why is not having a gag reflex good?
Not having a gag reflex can be concerning as it serves as a protective mechanism to prevent choking or aspiration of foreign objects into the airway or lungs. It is important for safely swallowing food and liquids. If someone lacks a gag reflex, they may be at a higher risk for aspiration and other respiratory complications.
What is the involuntary reflex during swallowing?
the tongue rolling the bolus into the pharynx
Why it is difficult to swallow saliva in rapid succesion?
It may be difficult to swallow saliva rapidly because the body has a reflex called the swallowing reflex, which can't occur too frequently in quick succession. This reflex helps prevent choking by coordinating the muscles involved in swallowing. Trying to swallow rapidly may disrupt this coordination and make it more challenging to swallow.
Is swallowing a reflex or instinct?
Swallowing is a reflex.
Swallowing a reflex action?
Yes, swallowing is a reflex action of which there are three phases. These are the oral phase, the pharyngeal phase and the esophageal phase.
What does the central nervous system have to do with swallowing?
Swallowing involves the central nervous system and is a reflex.
Food is forced into the digestive tract by the?
By the swallowing reflex.

What is the effector in a gag reflex?
The effector in a gag reflex is the contraction of muscles involved in swallowing, including the pharyngeal muscles in the throat. These muscle contractions help to expel any foreign objects that stimulate the back of the throat, triggering the gag reflex.
Which of the following is a feature of the muscular actions of digestion?
Peristalsis begins first in the stomach upon the initiation of the swallowing reflex
Is the larynx involved in the swallowing reflex?
No, your larynx is used for speech purposes; it contains your vocal chords. The main swallowing mechanism is your esophagus with help from the epiglottis (the flap that covers up your windpipe, keeping things from slipping into your bronchial tubes and lungs)
What is the muscular organ responsible for initiating deglutition?
The tongue is the muscular organ responsible for initiating deglutition, or swallowing. It helps to move food towards the back of the mouth and into the pharynx, which then triggers the swallowing reflex.
