Which of these is a reflex?
The knee-jerk reflex is a common example of a reflex. It occurs when the knee is tapped and the leg kicks out involuntarily in response.
What Prevents aspiration of food into trachea?
Several protective mechanisms prevent the aspiration of food into the trachea. These include the epiglottis, which covers the trachea during swallowing, the coordination of muscle contractions in the throat to direct food into the esophagus, and the cough reflex to expel any foreign material that might enter the trachea.
What structure covers the epiglottis?
During swallowing, the epiglottis covers the glottic opening to prevent aspiration of food or fluids into the lungs.
What acts as a lid over the entrance to the laryngopharynx?
The epiglottis is what acts as a lid over the entrance of the laryngopharynx. This is defined as a flap that is made of elastic cartilage tissue that is covered with a mucous membrane.
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.
Which of these is a reflex?
The knee-jerk reflex is a common example of a reflex. It occurs when the knee is tapped and the leg kicks out involuntarily in response.
What keep food from entering your air way?
the epiglottis closes over the glottis in a reflex action when food is swallowed. This prevent food from entering the respiratory system

What happens if we didn't have an epiglottis?
Food will go down the trachea into your lungs. This can cause a gagging reflex and you could sufforcate and die.
Why is the swallowing reflex important?
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.
Why does the Epiglottis move and what are its functions?
It is normally pointed upward during breathing with its underside functioning as part of the pharynx, but during swallowing, elevation of the hyoid bone draws the larynx upward; as a result, the epiglottis folds down to a more horizontal position, with its superior side functioning as part of the pharynx. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is at the back. The glossopharyngeal nerve (CN IX) sends fibers to the upper epiglottis that contribute to the afferent limb of the gag reflex. The superior laryngeal branch of the vagus nerve (CN X) sends fibers to the lower epiglottis that contribute to the efferent limb of the cough reflex.
The downward projection in the oral cavity that triggers the swallow reflex when it receives contact is the?
The downward projection in the oral cavity that triggers the swallow reflex when it receives contact is the epiglottis. It functions to cover the trachea during swallowing to prevent food or liquid from entering the airway.
What is a flap of tissue that closes the passage to the trachea and lungs?
It is the epiglottis.
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 keeps food from going down your windpipe?
There are two reasons this doesn't happen. One is that you cannot breate while swallowing, and the other is that the body has an involuntary reflex that prevents it from inhaling food.
Does touching of the penis turn guys on?
Usually, but it depends on the guy and where and how you touch him. In any case, it's a reflex -- it doesn't mean he likes you or is attracted to you. In fact, even though the reflex kicks in, it's possible that he will then get angry or upset if you touched it without his permission.
What is a flap of tissue that seals off your windpipe preventing food from entering?
That's your epiglottis.
