What does the term 'deglutition' refer to?

The term 'deglutition' specifically refers to the process of swallowing. It encompasses the complex actions involved in moving food from the mouth to the stomach, which requires coordination of the muscles in the mouth, throat (pharynx), and esophagus. Understanding this term is essential in the context of dental nursing, as it relates to how patients consume food and the implications for their oral health.

In contrast, breathing pertains to the inhalation and exhalation of air and is not directly related to the act of swallowing. Digestion refers to the breakdown of food into nutrients, which occurs after deglutition. Speaking involves the production of vocal sounds and is a separate function from swallowing. Therefore, the definition of deglutition aligns specifically with swallowing, making it the correct answer.
