Respuesta :

Answer:

all of the above are true.

Explanation:

  • The phase of swallowing that occurs involuntarily is termed as swallowing reflex.
  • The swallowing reflex occurs after mastication when the bolus has been formed and the food has to be swallowed in.
  • This reflex begins when the tongue is raised and presses against the uvula and the soft palate.
  • Following this, the epiglottis closes the top of the trachea to avoid the food to enter into the air passage and soft palate, larynx and hyoid bones get raised,
  • Finally, the muscles pull the pharynx upward towards the food and the food gets swallowed.
