During deglutition, the bolus is propelled down the esophagus into the stomach by a series of coordinated muscle contractions called peristalsis. Once in the stomach, the bolus mixes with gastric juices and is broken down further through mechanical churning and chemical digestion.

What is the pharangyeal stage of deglutition?
The pharyngeal stage of deglutition is the second stage of swallowing where the food bolus is moved from the back of the mouth and into the esophagus. During this stage, the soft palate elevates to close off the nasopharynx, the larynx elevates to close off the airway opening, and the food bolus is propelled down the pharynx by a series of coordinated muscle contractions.

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, consists of three stages: oral, pharyngeal, and esophageal. During the oral stage, the food is chewed and formed into a bolus before being voluntarily pushed to the back of the mouth. In the pharyngeal stage, the swallow reflex is triggered to move the bolus through the pharynx and into the esophagus. Finally, in the esophageal stage, peristalsis helps transport the food down the esophagus and into the stomach.
What is a ball-like masticated lump of food?
A ball-like masticated lump of food is called a bolus. It is formed in the mouth during the process of chewing and mixing food with saliva before swallowing. The bolus helps in the smooth passage of food through the esophagus and into the stomach for further digestion.
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 are a bolus and chime?
