Question

steps of swallowing
​

Answer 1

Explanation:

Swallowing, or deglutition, is a complex reflex mechanism by which food is pushed from the oral cavity into the esophagus and then pushed to the stomach.

This movement of food from the oral cavity on to the esophagus and stomach by pushing is called propulsion, and it is an important part of the digestive process.

This article will overview and detail the three phases of swallowing (oral phase, pharyngeal phase, and esophageal phase), including muscles involved, innervation, and clinical aspects.

Stages of swallowing (deglutition)

Table quiz

Oral phase

Bolus moves from oral cavity into the oropharynx; voluntary process

Pharyngeal phase

Bolus moves from the oropharynx into the esophagus; involuntary process

Esophageal phase

Bolus moves through the esophagus and into the stomach; involuntary process

To understand swallowing, we must first understand the digestive process. Recall that the digestive system is made up of organs that can be classified into two groups, the alimentary canal (or gastrointestinal tract), and accessory digestive organs. All of these organs have a particular function, and work together to process food.
