What is the pharangyeal stage of deglutition?
The Pharyngeal stage of deglutition - the bolus hits the pharynx and triggers reflexes (from this point it is no longer voluntary) --> the soft palate is raised, the glottis closed and the pharynx shortened --> pharyngeal constrictors move bolus into the oesophagus

What happen in deglutition?
Your epiglottis come down to close the respiratory tract. The food bolus is pushed back to enter the oesophagus.
What are the stages of deglutition?
Deglutition, or swallowing, can be divided into three stages. The oral, pharyngeal and oesophageal stages.Oral stage - the bolus of food is prepared --> the apex of the tongue presses on the palate --> rapid contraction of mylohyoideus and extrinsic muscles of the tongue propel the food (bolus) to the pharynx.Pharyngeal stage - the bolus hits the pharynx and triggers reflexes (from this point it is no longer voluntary) --> the soft palate is raised, the glottis closed and the pharynx shortened --> pharyngeal constrictors move bolus into the oesophagusOesophageal stage - peristalsis moves the bolus to the stomach
What is a ball-like masticated lump of food?
The mix of food and saliva made in the mouth is called a bolus.
What are a bolus and chime?

How do the cartilaginous rings of trachea looks like?
They are C-shaped, with the opening in the back so that when you swallow food, the esophagus expands into the area of the trachea to allow the food (called a bolus) to go down. This process is called deglutition. If they were not C-shaped and positioned this way, your food would not be able to go down into your stomach.
What happens when a bolus gets stuck in the trachea?
What happens when a bolus gets stuck in the trachea is that it makes breathing difficult. If the food is not removed from the trachea, the person could die.
