46. Which of these statements about the pharynx is TRUE?
Group of answer choices
The nasopharynx is involved in digestion.
The laryngopharynx is fully composed of cartilage.
The oropharynx is continuous superiorly with the nasopharynx.
It extends from the nasal and oral cavities superiorly to the esophagus anteriorly.
Once food has entered the pharynx, deglutition will become completely involuntary, and respiration will be inhibited by the swallowing center until the last stage of the process is completed. True or false and why.
